2:24 my life is complete, I made it into one of your videos lol. I’ll definitely sleep well knowing I have an engine with your stamp of approval under the bed in my motorhome! 👍
Man can you help me? I just replaced my fuel lines and my fuel shut off solenoid. I bypassed the mechanical lift pump with a electric one and it still feels like it's running out of fuel.
Was going to say the same thing. Creator had a problem, found a solution that saves time, and is easy to use. About as good as it gets engineering wise.
Convert it to uni-flow Clark cycle or a Day poppet valved loop scavenged 2 stroke. it would be worth a shit then. Cummins now makes an OP ACE 2 stroke uni-flow!
I used to do a lot of work on the 8.3 in sugar cane harvesters here in Florida. The biggest issue we had was head gaskets. The machine was using every bit of power they would put out. If they didn’t keep the radiator clean they would over heat and pop head gaskets. They would pour coolant out from under the head. I believe there was an issue with the gaskets and we put a new style in and did a different torque sequence. I got so good at head gasket jobs that I could drive a machine in the shop in the morning, pull the head, clean it all up, pit it all back together and drive it out by that evening. Sounds easy if it’s on a stand but we did it in the machine and the motor was in the middle so a lot of stuff to take off to get to the engine and climbing up and down on the machine. After that they were good to go. Also got a few reman engines they the rear main seal plate wasn’t installed correctly so the oil pan didn’t seal and they leaked oil like crazy. That was always a fun fix because we had the pull the engine which was a job. enjoy your videos.
You know a guy really knows a thing when he can explain it so simply and so well. I'm not a diesel guy, just someone who loves all kinds of machines and I always learn something from Rich and feel like I really understand all he explanations. Thanks!
This is the best 8.3 video I have ever seen. This engine is my bread and butter. I run them in snow-cats and routinely see over 10, 000 hours on them. Thank you.
You're videos are top-notch! I worked for John Deere for a few years and shadowed several field mechanics. Watching you is just like hanging out with a senior tech. Lots of great knowledge and no bs.
Also there was an update to the headgasket because they were prone to leaking at the front right corner. The head is almost always flat but it chafed causing a leak under load. Probably fixed 200 of these in the last 15 years
Now that you mention it I think I've had to help the father-in-law fix one leak at the front right but usaly for us it's the back 2 that usaly give out. We replace the gasket and the engines good for another 2+ years.
I’ve done a couple didn’t realise it was so common maybe we was lucky in the fleet I looked after I can’t imagine how much trouble it would of caused if we wasn’t.
I have a 8.3 Cummins in my "96" Monaco 38' MH, has 111,000 miles on it, uses no oil between changes, runs like a top! Great explanation Rich, thanks for review!
I have the exact same MH 8.3c with over 122k trouble free miles. I love the idea of the fully mechanical injector pump. Plan to put on at least 40 to 50k more miles. Monaco made a good machine back then!👍
@@razor3003 Yes many times! It gets anywhere between 9 MPG to my best was 10.5 MPG That is towing my toad, a PT Cruiser, 5 speed manual! It really depends on the wind, when the wind is blowing, you can expect around 9 MPG! I also run my diesel generator if it gets hot, to run the roof top A/C's! I have ran all the way up to Maine, and out to Custer, SD from central Illinois, and the MPG is always in the 9 to 11 range! My speed is around 62/65 MPH!

I just woke up and wanted to watch videos on my RV engine. Had a coffee and enjoying learning about my 94 C series. It's been a great engine although you should keep an extra cog belt around, I sourced a couple off ebay for less than $200. I had to get one replaced by a roadside mechanic once out on the highway in the middle of nowherevill Kentucky and I ended up paying $1,200 to replace a belt. Took one tool and a belt.
Cavitation erosion is from the small bubbles from the piston vibration imploding against the liner wall.. I’ve seen it so bad it makes a hole right through and fills cylinders and leaks around the piston. Love your RUclips channel
Had one spin the crank gear on the shaft, sheared the woodruff key right proper. Pulled gear, reinstalled, welded it to crank and sent it. Love the video, and yeah, just hoping that parent sleeved 3126 going in my truck stays good. Keep it up Rich!
So in Maine where everything rots and rusts out. the exhaust ears will crack in the head side. The bolts and exhaust-gaskets will rust jack and crack the castings that the manifold bolts to. Good video 👍🏻
@deboss garage, I know one of the engineers that worked on the B series at Darlington and he maintains that the dowel pin is not an issue until people start replacing the injection pumps and do not refit the support bracket correctly on the injection pump or in some cases not at all. The increased moment on the timing case causes movement and it works the dowel loose. Theres a service bulliten on this particular issue on the B somewhere.
I’m the assistant service manager (basically manage the service writers and shop infrastructure) at a large diesel shop, I come from being a master auto tech so I know how Diesel engines work and understand it all and could repair one, but im behind the curve on common issues with these engines and the techs give me a ton of flack for it (Then I remind them who rebuilt there wife’s transmission or made a brake line for their truck and we’re even) but these videos make me surprise the guys when I know the common issues or the way things are set up and I absolutely love it.

@@Jaxon-iu6vb nah. If they he ran at 100% load they where running the combine to hard. Combine engines have a relatively easy life. Constant medium load, constant engine rpm. Basically almost as easy of a life as a gen set or air compressor engine. They’ll last forever

Hey man love the channel, one thing to note about the 8.3 from what I’ve seen in my repairs, in ag equipment it’s common to see the head gasket leak out in the front or rear corner, combine had it at 3500hrs and a magnum had it at 5500hrs. Something to look out for
I was always wondering what the problem was specifically with the CAPS 8.3 and you explained it. See a lot of older used farm equipment with the 8.3 CAPS power. Now I know what to be looking for on one of those.
S. Stewart we had one for towing a couple sherps on a 30ft flat deck. Made a couple trips and then ended up in the shop for a limp mode. Last I checked they were still trying to diagnose it. The truck had 30,000ish kms
Be interesting to see one swapped into an older 4 door SUV (Jeep JK, Durango, Yukon, Tahoe, 4 runner, Explorer, Expedition, even Excursion maybe) running using a LB7, LLY, etc (pre emissions) computer.
Definitely having flat tappits for the lifter's with no room for rollers was the number one reason I used to rebuild 8.3 in garbage trucks converted to silage trucks
What an excellent video - thank you for making it. I have an ISC 315 in my motorhome and it was good to hear confirmation of what I've always thought, that it's a pretty sound engine without too many issues.
Happy to be educated with the difference between the 8.3 and 5.9 p-pump. Did not get a call back from someone that was selling his 8.3 p-pump that was going in my 5.9. So thankful to watch this vid for future p-pump buying purchases to avoid losing money.
I love these videos. Every time he shows something cool, I get a stupid idea I’m ready to google, then before I can he already knows I thought of it and tells me I really shouldn’t do it, and why.
I love that you're honest about these engines. I'm a cummins guy for life but, even I know(lots of firsthand experience lol) that they have somewhat annoying issues..😂😂
The failure of number 6 cylinder is helped if you add a water aid to the rear of the head like the marine engines. The injector pump on the engines less than 350 horse have 10 mm plungers 5.9 has 12mm. Older cool blocks have thicker lines and thinner blocks that tend to cause block failures behind the injector pump caused by the clamping force of the head bolts on the cylinder counter bore.
VP44 and CAPS are very different and failure mods are very different. The problem with CAPS is mainly confined to the pump and surge suppressor/ transient diode. VP44 is the one with fuel lift pump problems. Most issues with CAPS were resolved with later changes. Though they both use the same lift pump design you are less likely to kill a CAPS pump with lift pump failure.
What a superb tool, the best design sleeve puller I've seen. Would have loved to have that 20 years ago when I was the kid under the engine eating anti-freeze :(
I'd like to see you do a dt360. Heavier than a 5.9 but the wet sleeve, and I've seen guys make crazy power with them. Still research stage but I'm thinking better swap than a 12valve.
Love the knowledge of the Cummins engine, can only come from hands on. Knowing that about those engines, also tells a great deal about the History of mechanics. keep up the good work.
Where do people get Cummings from? It clearly says CUMMINS on all of their products and ram trucks. Cumming is what porn stars do. Cummins makes diesel engines
We use to use the Dongfeng-Cummins 6CTAA8.3 in our 200kVA gensets (moved to Perkins 1106). They worked very well and could do high hours but with a lot of the Dongfeng-Cummins, they leaked oil, in particular from the oil cooler.
i believe the cavitation is from the intense combustion (slight pre ignition) of a diesel ringing the cylinder like a bell, not the piston rattling. I read that somewhere. Great video.
Pretty much got all of it But forgot one another pretty common issue which is the rear cam plug that leaks which always gets mis-diagnosed as a rear main seal leak but looks like a sump gasket leak
7000 hour rod kick outs in combines are due to "farmer maintenance". We run them well into the 40k hour mark and pull them for overhaul. I've been tractor pulling with them for 12 years and well over the 1000 horse mark and 3000 ft lbs. They did address the coolant out problem with the newer common rail (which is my block of choice) and roller blocks.
Ya 43,000 hours on my July 1999 Built Cummins N14, 4,300 Idling hours (Day Cab so it is shut off every night). 10 lb of oil pressure at operating temperature at idle and 30 lb of oil pressure above 1000 RPM at operating temperature just as the specifications given in Publications on the engine.
Great video, we have 3 8.3's at my shop, my 1993 which had a problem with the front timing cover cracked and dump the oil, what a job that was. That engine also had plenty of other problems. The other 2 8.3's had electronic problems. We don't consider them any good. I switch to a 1988 L-10 in my single axel dump. Thank you for taking the time to make this video, I am a new subscriber.
That dowel on the B series only comes off if a fuel pump or compressor is mounted incorrectly causing the timing case to flex over time. It will never happen in a stock engine, hence why Cummins never issued a "fix" for it.
As some others here have stated, Liner pitting on some engines has been found to becaused by electrolysis. As the liners are not thourghly grounded to the block. Also been found to be a cause of cylinder head corrosion.
How would a liner not be grounded if they're assembled with a small interference? They should have full contact with the block (if properly made and installed without warping and leaks). If the block isn't properly grounded, then that would be a issue for the whole engine, even with some problems starting it up, not to mention premature and excessive rusting. The mechanics of damage by cavitation involve localized rusting, so a localized electrolysis does happen to form pits, but that only occurs either by a bubble of water on metal or a bubble of air in a water solution, the latter being the case, but that bubble only occurs due to vibration, since tge system is pressurized and shouldn't bubble up!
@@chaoswarriorbr If a liner is installed and has coolant or oil on the interference then poor grounding can result. Its not the block thats poorly grounded its the Liner to the block. Also has been found to be a problem with cylinder heads. And Yes the head gasket can be an insulator so can the head bolts with thread sealant or lubricated threads can cause poor grounding. Caterpillar has done studies on electrolysis and found that this can be a cause of liner pitting not caused by cavitation.
@@larrydunlop378 As I said: "if properly installed" Though I'm surprised coolant and/or oil should be covering all the contact surface anyway. That requires one heck of a talent to do a shitty assembly job! Also, I think you've missed the point of my comment on the mechanics of such damage. All pitting happens, in a direct way, due to electrolysis, the way that this happens might vary in the specifics, but the cavitation issue might happen even if everything is properly grounded, just like I've commented before. Assuming is just electrolysis due to bad grounding is just not true overall and it's a bad maintenance practice without further investigation of each specific case. There's plenty of Material Engineering studies supporting the specific mechanics of a "battery" created because of a bubble of a aqueous solution or a buble of gas in a aqueous solution.
Love love love (!!!) the 8.3 in our case ih magnum 7120 tractor. 30 years old, 5500 hours on it with zero engine issues. Bump the key and it's running and will keep running all day. Our r65 gleaner has the caps 8.3. When it runs good it really runs good. However when gleaner bought these engines they did not get software diagnostic capabilites with them. Means having to deal with a Cummins dealer 2 hours away rather than the gleaner dealer 15 minutes away. Every few days during harvest I'm driving the combine with 1 hand and using my phone internet searching the latest trouble code set with the other. Mechanically the engine has been fine but that caps will be the reason the machine gets traded away before its time.
The 8.3L 6CT is actually in the M923A2-M943A2 five ton trucks for 1987 to 1994,those trucks were made by BMY Harsco too,but you are correct,just off by some years. The M923-M943 & M923A1-M945A1 which came BEFORE the M923A2-M943A2 going back to 1982 all have the 14.0L NHC-250,and the M812-M820 used the same engine in early years too.The M923-M943 and M923A1-M945A1 were made by AM General too,and it's easy to tell the difference between the three variations of those trucks,the M923-M943 has G177 dual tires which are 42 Inch (1100×20) and then the M923A1-M945A1 have super single Michelins "XL" that are 48 Inch (1400×20) and finally,the M923A2-M943A2 also have super single tires which are 50 Inch. The reason why they stopped production for them in 1994 was because of the Stewart & Stevenson M1078-M1088 FMTV,at least in the Army.For the Seabees and Marines,the Oshkosh MK23-MK38 MTVR came out a few years later,which replaced the M939 Series.
On the last 8.3 i worked on last year i just used a cat sleeve puller. The puller's feet just fit on the engine deck but it work fine. You just got to make sure that the pullers "hookes" that go on the bottem of the sleeve dont touch the sleeve retaining webbing in the block, if it does it would damage the puller and the block.
OntarioRedneXXX No you gotta stay filthy to truly be rich. You want people to think you’re a bum. Cleaning up just means you wasted all that filth and you’re left with nothing but peoples opinions. Doesn’t matter what they think
my company built the M1117 ASV for the Army. We used the 6CTA, which has the liquid cooler in the intake. We had very few problems with these engines in almost 5000 vehicles we built for the U.S. Army as well as other countries. Ours was rated at 260hp and something like 840 torque.
Like the guy says in the video, the Cummins 8.3 was a popular motor. Some road tractors like the Freightliner FL70 ran it. Sometimes with a 10 speed manual, or, an Allison automatic. Even some fertilizer spreader trucks had ‘em
did the fl70 have a air splitter? I picked up a free parts truck with a 8.3 and a manual transmission but there's no shift patterns marked in the cab. i figured it was just a 6 speed but I'm trying to figure out how to identify what transmission I do have before I start swapping it into my c60. I know I'm going to be doing a bit of sheet metal work. but help identifying the transmission would be awesome
I am looking at a 2001 Monaco Diplomat and it has a Cummins 330HP ISC. I believe it has the CAPS systems. It has 80k miles. Would it be advisable to go ahead and replace the CAPS system?
If I were you I would just replace the diode in the line as preventative maintenance. I have a 2000 Diplomat. And be certain the lift pump works as they do fail. And be sure to change BOTH fuel filters regularly.
The US Military used the 8.3 in the M939 series 5-ton trucks made by AM General. The rated horse power in that application was 240 hp. The 8.3 was significantly lighter than the NHC-250 the 855 cubic inch NA engine that it replaced . The weak link with the engine in military application is the water pump and the steel line used for oiling the turbocharger.
You are correct,but the M923A2-M943A2 was not made by AM General,all of them were manufactured by BMY Division of Harsco actually.The M923-M943 and M923A1-M945A1,which had the NHC-250 were the only ones made by AM General,the A2 was only for 1987 to 1994,the first M939's and then the A1 go as far back as 1982,the A1 came out in 1984/85.The NHC-250 was also the only engine ever used in the M812-M820,for 1969 to 1982,and they were all manual,they did not have Allison Automatics in the M809 trucks like the M939 trucks do. Those trucks also had errors with rusty springs in the Overflow Valves and some of them not having Hydraulic Hoses,which were always better for them.For the most part,they had issues with the fuel systems in the long run.
Back when i lworked in a truck shop I swapped 8.3s in a delivery truck, original engine probably would have lasted longer but the customer wasn't keen on maintenance and the coolant filter rotted off. Short while later he needed a tow and an engine lol.
My 2002 Holiday Rambler Ambassador has this engine, 8.3 with a vp44 I did put a fass fuel pump on it to prevent my vp44 from getting air locked and burning out on me.
@@Seth_Stewart nah its gotta be something crazy and over the top. They already have a 6.7 duramax in a Camaro so you gotta beat, or match it lol. Preferably beat it... but an 8.3 in a demon would be pretty damn near impossible I think.
would really love to see you do a review on the L10 cummins. and you do a great job of explaining everything, thanks i have learned alot for watching you channel.
We have these in a lot of our public service buses. All at least 17 years old. Most have their original engines with 1million miles or more, our oldest ones are 20. There's a couple that have done over 2 million miles that are still in daily service, sounding and running like new. Plenty of power still!

@@TeamTopKick Yeah them 2 strokes last long if you treat them right.
Hey man love the channel, one thing to note about the 8.3 from what I’ve seen in my repairs, in ag equipment it’s common to see the head gasket leak out in the front or rear corner, combine had it at 3500hrs and a magnum had it at 5500hrs. Something to look out for
We had a lot of blue bird buses with 8.3's love the torque to me our 04-05 have more power than our newer 6.7 with the dpf bullcrap
I was always wondering what the problem was specifically with the CAPS 8.3 and you explained it. See a lot of older used farm equipment with the 8.3 CAPS power. Now I know what to be looking for on one of those.
I’d love to see your take on the 5 l Cummins that Nissan had
They pretty well stopped making them but I know where there are a couple on engine stands. Maybe someday. One project at a time
That was a delivery truck engine first. Lots of problems I heard
S. Stewart we had one for towing a couple sherps on a 30ft flat deck. Made a couple trips and then ended up in the shop for a limp mode. Last I checked they were still trying to diagnose it. The truck had 30,000ish kms
@@Seth_Stewart the 5.0L Cummins in an XD is basically same real world capability as a 90s f250 7.3 PSD from folks that I've talked to
Be interesting to see one swapped into an older 4 door SUV (Jeep JK, Durango, Yukon, Tahoe, 4 runner, Explorer, Expedition, even Excursion maybe) running using a LB7, LLY, etc (pre emissions) computer.
Definitely having flat tappits for the lifter's with no room for rollers was the number one reason I used to rebuild 8.3 in garbage trucks converted to silage trucks
Id actually love it if you could one day look in this ludicrous TD42 diesel motor we love and hate so much over here in New Zealand...
The mighty kettle
Would also love to see that hahahaha
The mighty kettle indeed hahaha
What an excellent video - thank you for making it. I have an ISC 315 in my motorhome and it was good to hear confirmation of what I've always thought, that it's a pretty sound engine without too many issues.
Wow the lighting makes a world of difference!
Happy to be educated with the difference between the 8.3 and 5.9 p-pump. Did not get a call back from someone that was selling his 8.3 p-pump that was going in my 5.9. So thankful to watch this vid for future p-pump buying purchases to avoid losing money.
I love these videos. Every time he shows something cool, I get a stupid idea I’m ready to google, then before I can he already knows I thought of it and tells me I really shouldn’t do it, and why.
I love that you're honest about these engines. I'm a cummins guy for life but, even I know(lots of firsthand experience lol) that they have somewhat annoying issues..😂😂
The failure of number 6 cylinder is helped if you add a water aid to the rear of the head like the marine engines. The injector pump on the engines less than 350 horse have 10 mm plungers 5.9 has 12mm. Older cool blocks have thicker lines and thinner blocks that tend to cause block failures behind the injector pump caused by the clamping force of the head bolts on the cylinder counter bore.
VP44 and CAPS are very different and failure mods are very different. The problem with CAPS is mainly confined to the pump and surge suppressor/ transient diode. VP44 is the one with fuel lift pump problems. Most issues with CAPS were resolved with later changes. Though they both use the same lift pump design you are less likely to kill a CAPS pump with lift pump failure.
What a superb tool, the best design sleeve puller I've seen. Would have loved to have that 20 years ago when I was the kid under the engine eating anti-freeze :(
I LOVE LOVE LOVE the info graphics!! Way easier than following someone spitting off a list of stats
Thanks for all the info man! I'll take "8.3 swap" off the to do list for the 1st gen hahah...a whole 4BT heavier than a 5.9...That's heavy!
love these cummins med duty engines, been working on them in refuse trucks for years. nothing bad to say about them
I am not a diesel guy, but love your information and work......
I'd like to see you do a dt360. Heavier than a 5.9 but the wet sleeve, and I've seen guys make crazy power with them. Still research stage but I'm thinking better swap than a 12valve.
Excellent video. About the hole in the block issue not much was mentioned about how to prevent it unless I missed it.
Love the knowledge of the Cummins engine, can only come from hands on. Knowing that about those engines, also tells a great deal about the History of mechanics. keep up the good work.
Some knowledge comes from a quick glance at the valve cover and reading the word CUMMINS.
Hack CUMMINS!
Where do people get Cummings from? It clearly says CUMMINS on all of their products and ram trucks. Cumming is what porn stars do. Cummins makes diesel engines
@@benjaminturpin2749 Is that better? Cummins
We use to use the Dongfeng-Cummins 6CTAA8.3 in our 200kVA gensets (moved to Perkins 1106).
They worked very well and could do high hours but with a lot of the Dongfeng-Cummins, they leaked oil, in particular from the oil cooler.
Could you do more on this engine would love to see a reliability test compared to a 5.9 Cummins
i believe the cavitation is from the intense combustion (slight pre ignition) of a diesel ringing the cylinder like a bell, not the piston rattling. I read that somewhere. Great video.
Really cool video Rich. This is one of my favorite channels!
Pretty much got all of it
But forgot one another pretty common issue which is the rear cam plug that leaks which always gets mis-diagnosed as a rear main seal leak but looks like a sump gasket leak
7000 hour rod kick outs in combines are due to "farmer maintenance". We run them well into the 40k hour mark and pull them for overhaul. I've been tractor pulling with them for 12 years and well over the 1000 horse mark and 3000 ft lbs. They did address the coolant out problem with the newer common rail (which is my block of choice) and roller blocks.
Ya
43,000 hours on my July 1999 Built Cummins N14, 4,300 Idling hours (Day Cab so it is shut off every night). 10 lb of oil pressure at operating temperature at idle and 30 lb of oil pressure above 1000 RPM at operating temperature just as the specifications given in Publications on the engine.
@@michaeldunagan8268what’s your maintenance schedule on that motor?
Great video, we have 3 8.3's at my shop, my 1993 which had a problem with the front timing cover cracked and dump the oil, what a job that was. That engine also had plenty of other problems. The other 2 8.3's had electronic problems. We don't consider them any good. I switch to a 1988 L-10 in my single axel dump. Thank you for taking the time to make this video, I am a new subscriber.
Thanks for blessings others with your knowledge! Keep up the good work
That dowel on the B series only comes off if a fuel pump or compressor is mounted incorrectly causing the timing case to flex over time. It will never happen in a stock engine, hence why Cummins never issued a "fix" for it.
I have the 8.3 In my 1994 CaseIH 7120...... Been a great Engine but why do they always leak on the front covers!! My 5.9 Is leaking oil to!
I just found you. I don't know jack about engines. You have a new subscriber. Great vids. Thanks for helping the world! 💚
Thanks Rich ... Infotainment at its best!
As some others here have stated, Liner pitting on some engines has been found to becaused by electrolysis. As the liners are not thourghly grounded to the block. Also been found to be a cause of cylinder head corrosion.
How would a liner not be grounded if they're assembled with a small interference?
They should have full contact with the block (if properly made and installed without warping and leaks). If the block isn't properly grounded, then that would be a issue for the whole engine, even with some problems starting it up, not to mention premature and excessive rusting.
The mechanics of damage by cavitation involve localized rusting, so a localized electrolysis does happen to form pits, but that only occurs either by a bubble of water on metal or a bubble of air in a water solution, the latter being the case, but that bubble only occurs due to vibration, since tge system is pressurized and shouldn't bubble up!
@@chaoswarriorbr If a liner is installed and has coolant or oil on the interference then poor grounding can result. Its not the block thats poorly grounded its the Liner to the block. Also has been found to be a problem with cylinder heads. And Yes the head gasket can be an insulator so can the head bolts with thread sealant or lubricated threads can cause poor grounding. Caterpillar has done studies on electrolysis and found that this can be a cause of liner pitting not caused by cavitation.
@@larrydunlop378 As I said: "if properly installed"
Though I'm surprised coolant and/or oil should be covering all the contact surface anyway. That requires one heck of a talent to do a shitty assembly job!
Also, I think you've missed the point of my comment on the mechanics of such damage. All pitting happens, in a direct way, due to electrolysis, the way that this happens might vary in the specifics, but the cavitation issue might happen even if everything is properly grounded, just like I've commented before. Assuming is just electrolysis due to bad grounding is just not true overall and it's a bad maintenance practice without further investigation of each specific case. There's plenty of Material Engineering studies supporting the specific mechanics of a "battery" created because of a bubble of a aqueous solution or a buble of gas in a aqueous solution.
I wish I could see a video on a 2.5 jerrkin Perkins. You do make to the point great videos + pertinent cat cameo's.
Most comments about block failures mention use in combines. Any data on longevity in motor graders ??
Love love love (!!!) the 8.3 in our case ih magnum 7120 tractor. 30 years old, 5500 hours on it with zero engine issues. Bump the key and it's running and will keep running all day.
Our r65 gleaner has the caps 8.3. When it runs good it really runs good. However when gleaner bought these engines they did not get software diagnostic capabilites with them. Means having to deal with a Cummins dealer 2 hours away rather than the gleaner dealer 15 minutes away. Every few days during harvest I'm driving the combine with 1 hand and using my phone internet searching the latest trouble code set with the other. Mechanically the engine has been fine but that caps will be the reason the machine gets traded away before its time.
5500 hrs? It’s just getting broke in lol
I can only speak from fire truck applications but I seen alot of head gaskets causing external oil leaks on these engines.
8.3 is the engine found in the Military 5 Ton's, 80's to 1995
The 8.3L 6CT is actually in the M923A2-M943A2 five ton trucks for 1987 to 1994,those trucks were made by BMY Harsco too,but you are correct,just off by some years.
The M923-M943 & M923A1-M945A1 which came BEFORE the M923A2-M943A2 going back to 1982 all have the 14.0L NHC-250,and the M812-M820 used the same engine in early years too.The M923-M943 and M923A1-M945A1 were made by AM General too,and it's easy to tell the difference between the three variations of those trucks,the M923-M943 has G177 dual tires which are 42 Inch (1100×20) and then the M923A1-M945A1 have super single Michelins "XL" that are 48 Inch (1400×20) and finally,the M923A2-M943A2 also have super single tires which are 50 Inch.
The reason why they stopped production for them in 1994 was because of the Stewart & Stevenson M1078-M1088 FMTV,at least in the Army.For the Seabees and Marines,the Oshkosh MK23-MK38 MTVR came out a few years later,which replaced the M939 Series.
On the last 8.3 i worked on last year i just used a cat sleeve puller. The puller's feet just fit on the engine deck but it work fine. You just got to make sure that the pullers "hookes" that go on the bottem of the sleeve dont touch the sleeve retaining webbing in the block, if it does it would damage the puller and the block.

I am considering buying a F800 with an 8.3 mechanical, this video sealed the deal for me.
Fantastic! Great explanation. Great visuals. You make it look easy.
my company built the M1117 ASV for the Army. We used the 6CTA, which has the liquid cooler in the intake. We had very few problems with these engines in almost 5000 vehicles we built for the U.S. Army as well as other countries. Ours was rated at 260hp and something like 840 torque.
@deboss garage thanks for teaching me something!! I appreciate it
Holy shit, that overhead console in the motorhome looks just like mine. Missing head knocker TV and all.
You do a great job. Very informative
Much appreciated
Like the guy says in the video, the Cummins 8.3 was a popular motor. Some road tractors like the Freightliner FL70 ran it. Sometimes with a 10 speed manual, or, an Allison automatic. Even some fertilizer spreader trucks had ‘em
did the fl70 have a air splitter? I picked up a free parts truck with a 8.3 and a manual transmission but there's no shift patterns marked in the cab. i figured it was just a 6 speed but I'm trying to figure out how to identify what transmission I do have before I start swapping it into my c60. I know I'm going to be doing a bit of sheet metal work. but help identifying the transmission would be awesome
What engine should we review next? 🤔
I know it's a little newer than what you like working with but what about an LML Duramax motor??

DEBOSS GARAGE 855 Cummins
We had a mid 90s L9000 jet fuel truck with 8.3l, for at least 10 years it had a broken head bolt and never missed a beat running 18-20 hours a day.
That sleeve removable tool would pay for itself in like a week at a shop. Great idea.
I am looking at a 2001 Monaco Diplomat and it has a Cummins 330HP ISC. I believe it has the CAPS systems. It has 80k miles. Would it be advisable to go ahead and replace the CAPS system?
If I were you I would just replace the diode in the line as preventative maintenance. I have a 2000 Diplomat. And be certain the lift pump works as they do fail. And be sure to change BOTH fuel filters regularly.
The US Military used the 8.3 in the M939 series 5-ton trucks made by AM General. The rated horse power in that application was 240 hp.
The 8.3 was significantly lighter than the NHC-250 the 855 cubic inch NA engine that it replaced .
The weak link with the engine in military application is the water pump and the steel line used for oiling the turbocharger.
You are correct,but the M923A2-M943A2 was not made by AM General,all of them were manufactured by BMY Division of Harsco actually.The M923-M943 and M923A1-M945A1,which had the NHC-250 were the only ones made by AM General,the A2 was only for 1987 to 1994,the first M939's and then the A1 go as far back as 1982,the A1 came out in 1984/85.The NHC-250 was also the only engine ever used in the M812-M820,for 1969 to 1982,and they were all manual,they did not have Allison Automatics in the M809 trucks like the M939 trucks do.
Those trucks also had errors with rusty springs in the Overflow Valves and some of them not having Hydraulic Hoses,which were always better for them.For the most part,they had issues with the fuel systems in the long run.
I had 2 of the 8.3 throw a rod thru the block in one month on 2 different 1680 combines, about 4500 hours. Scott
"It's *aboat* 2000 lbs."
Back when i lworked in a truck shop I swapped 8.3s in a delivery truck, original engine probably would have lasted longer but the customer wasn't keen on maintenance and the coolant filter rotted off. Short while later he needed a tow and an engine lol.
Can you do a review on overhead cam iveco or any Iveco engines
I drive a 89 Volkswagen, currently with 385.000 miles and the 6CT is still running strong!!!
Great video thanks for sharing.
Our Mx285 CAPS pump made it about 4000 hrs. Haven't got it back yet to know the cost.

We have these in a lot of our public service buses. All at least 17 years old. Most have their original engines with 1million miles or more, our oldest ones are 20. There's a couple that have done over 2 million miles that are still in daily service, sounding and running like new. Plenty of power still!
