Would love to see a video on the 3406 A, B, and C. Especially the white 3406B. Had one in a 1984 362 Pete that only the heavy equipment Cat shops could seem to make run great. Thanks for all you share, I have learned a lot from your videos.
C7 history is simpler, which is a good thing. Although there is a C7.1 now, that is a completely different engine, not sure what Cat is thinking sometimes. Merry Christmas to you guys.
Josh I would love to see a video on the 3408 engine. My favorite Cat mechanic called them "Yellow Boat Anchors." He finally got me to get rid of mine and get a 3406 5DS. My mileage improved and the drivetrain took less of a beating. The V8s had a sound all their own, but there was a vibration that was bad.
Great video, sounds pretty accurate 👌. You said the 3406E and C-15 are the same, you can tell the difference at a glance because the 3406E still used the puzzle oil pan gaskets...whereas the C-15 went to the thick rubber Gasket. 😉
Excellent video Josh! Thank you! Very informative and educational. This actually is a very helpful tool for me because I don't get to choose what I have to fix each day... it's just whatever is broke that day lol
Enjoyed your video. I absolutely love my 3406 2WS cat. I bought it in a Fitzgerald glider and Nashville Caterpillar rebuilt the motor, they did a fantastic job! Looking forward to the next video. Merry Christmas!
Wait a minute, so if we thought outside the box and wanted an original higher horsepower engine. We could stick a 3456 engine in a semi truck? Could you maybe one day if you get a chance talk more about the 3456? Thank you very much for your videos!
Awesome tech video thanks Josh, down here in New Zealand we predominantly see the 6nz series and the acerts. I used to drive a K100E with a 3406b that had been turned up from 425 to approx 500hp, was amazing on hill climbs, especially when you pre- heated the engine prior to climb and would routinely see slightly above 560 degrees c on the pyro🙏 that engine was the godfather.
@@AdeptApe I watch your stuff religiously as you are one of the few people that willingly shares your experience and as I work for a company that is MAN, Western Star and detroit I find it very hard to get any info from our local cat dealers so much appreciated as always and merry Xmas to you and yours🙏🤗
The only work I've done on CAT engines is PM services and now that I don't turn wrenches I'll probably never touch one again. Dang if I don't learn a ton and enjoy the heck out of your videos, though! Great work!
@@johngoldsmith6629 I knew all that but was wanting Adept Ape to get into difference(s) in fuel systems and in the injection itself. If I remember right the A model DI engines had 5000 psi into the chamber and the B model engines had something like twice that much psi. Of course the PC engines were totally different as far as pressures and location of the actual injection.
@@guyconnell2250 C models I was told was in 17,000 injection psi. Go ahead and tell me what you already know so I don't have to repeat myself. Been with Cat over forty years.
Thanks Josh. You and your family have a great Christmas and blessed New Year. And of course we want to see the videos of the 3408 and other large Cat engines.
I have a 6nz factory 550 ,had a cat 600 flash file installed . Apparently its a file for fire trucks. Anyways whatever they did it woke that muther fker up . Felt more like 100hp gain . Single turbo boost showing between 40-45 lbs . Really enjoy your content. Keep it up.
Great video. Please make a video on the 3408, 3412 and maybe even the 3508. Specifically WHY these engines have off-set rod journals on their crackshalfs. Thanks!
The 3508 has offset rod journals because of its crossplane (up-right-left-down) crankshaft and 60° V angle, and what ends up happening is the crankpins have to be split by +60°, -30°, or -120° to get 90° firing intervals. A -30° split was chosen because it has the smallest magnitude and does not require "flying arms" unlike most (4-stroke) 60° V6's. However, one problem still remains. The 90° crossplane V8 relies on crankshaft counterweights to achieve perfect primary balance and therefore does not (assuming an up-right-left-down or up-left-right-down crank) require any balance shafts. However, with the 3508 and its 60° V angle, not only did Cat need to add the -30° crankpin split I mentioned before, they also needed to add supplemental counterbalancing because the 3508 has a rocking moment. While Yamaha, on their 60° V8 outboard engines (which is the same crankshaft configuration) use a counter-rotating balance shaft to address this, Caterpillar use unbalanced timing gears instead, so they do not beed to have a shaft running down the block. That's also why the 3508's have an extra timing gear in the front (which is a second balancer gear) whereas the 3512 and 3516 do not have this extra gear. The 3512 is even firing with the 60° V angle and non-split crankpins. Nothing really special. The 3516, however, does not fire evenly. It is a 60° V16 with non-split crankpins, and what ends up happening is that the enngine fires UNevenly, with firing intervals of 60° from left to right, and intervals of 30° from right to left.
C18 Industrial prefix with the parallel twins crank out over 900 HP, and do it with ease in some brutal applications. Track-type tub grinders running 14-16 hrs a day in the Texas heat, Cat Emergency fire pump C18 is over 1K HP... Love the high hp continuous duty rating in a dead simple inline platform.
Merry christmas Josh, Always a pleasure to watch your videos, lots of information, in an easy to understand way. Keep up the good work! I would like to see one on the old A-B series thanks.
Yeah. I don't know how many times some part of a cat went bad and cost me a lot of money after replacing it several times before cat would say "that is a factory defective part and is on a recall list" but wouldn't warranty it!!!!!!!!!!!!!!!!!!

@@anrew1000 IPD are making what they call a Big Bore Kit that will turn your 15.2L C15 Acert into a 16.9L "C17". I believe KT3406E mentioned that IPD are also working on similar kits for the 14.6L engines (3406E and C-15) that will turn them into a 16.3L C16.
Marine engines cheat with their unlimited heat transfer abilities and then they also run them up to 2300 rpm horsepower curve sometimes, how is a truck engine at 1800 rpm supposed to fight fair?

@@gm16v149 Gday Mate, I'm one of your subscribers also, Yeah nothing like that v8 Cat sound. Thanks for the info and hope you put out some more vids soon
3406 now called A model, first cylinder blocks from 1 to just under 06000. They oiled rocker arms from the head bolt holes and would put oil in the radiator. Cat did a modification to the spacer plate to stop this. Accessory drive air compressor likes to leak oil. You take a 1S9540 dowel if I recall, a letter size U drill bit. Drill into the front hsg and drive and install the dowel. Biggest problems on this series. They came PCTA, DIT, DITA. You cannot mix these parts will cause problems. Seen PC pistons put in DI engines and they smoke. 3406B Cat dropped the DIT and went only to DITA. First engine was a 7FB, used a A model head and it got finally changed in the nozzle chamber area. The front cover was changed and went to New Scroll Fuel System, and to 7000 series nozzles from capsule type. Went from a slide VTU to a hydro-mechanical that is adjustable. Can leak oil around accessory drive. Then with 4MG03600 fuel system camshaft and VTU was changed. Also JWAC I think was dropped and went strictly to CAC. 3406C Emissions is the biggest change I would say. A 3ZJ engine B or C model is the only truck engine that if you go by the parts book you will put the wrong nozzles in it. 3406C 8PN, is a odd engine and lots of changes, pistons, head, exhaust manifold etc. Again just to meet emissions. Starting at 4MG03600 and to 8PN series. Numerous VTU changes as they had problems with carrier slipping, bolts backing out and such. Starting in the early 3ZJ, era and other engine prefixes in this time frame the rod journal was increased, also other changes to the connecting rod. You have to get the article as it is a lot to type. Injection pump hsg changed and increased cam journal size. The injection pump went from a single helix (early B models) to a dual helix (later B models) and the played with the check valve design. As fuel psi was increased for emissions a lot of fuel lines would break. If you didn't have the proper clamps they failed fairly quickly. Best to use the 8PN set up and I do some changes to it as well. Emissions is the biggest so you have several piston compression ration and such, fuel system camshaft for timing and a few engine camshaft designs. Again a lot of typing and not worth it.
I would like to know more about all the “mechanical” 3406’s (A’s, B’s and C’s). Why are they so popular? Why is there a mechanical C and also a electronic C, but no D? Thanks for your time! I like watching all your videos and learn a lot from them.
Well the C engines were electronic, but with a mechanical fuel injection pump. A bad compromise in my opinion. I believe they went to the E model to signify Electronic more than a model progression as the engine changed tremendously from the C to the E.
A b and early C's were very easy to turn up. Last C's were bastard stepchildren because they were kind of mechanical and electronic. I think they skipped d because after the c model they went pure electronic.
@@rodneyward8357 3406 (now called A model) was a PCT, PCTA, DIT, DITA. (1973-1984) 92U prefix. 3406B at first was a 7FB, JWAC DITA, later ATAAC was added. As they ran out of serial numbers, the first 4MG's 1-03599 was still basically the same and still could be a JWAC. Starting at 4MG03600 the VTU was the major change. And they went into the 90,000 serial numbers. Then they came out with a 5KJ and it was a 3406B, 1-07799. Most people get this serial number mixed up is the 3406 B 3ZJ, serial numbers 1-16181 is a 3406B. During the late 80's the dreaded PEEC was released. Electronic governor and VTU. You had PEEC II, PEEC II.V They started out as a 3406B 8TC. released next of the PEEC was a 2EK, still a 3406B. Last PEEC was the 4CK and it was a 3406B 1-0845. Another 3406B PEEC was a 5YG strictly a 460 HP @1900 RPM'S. After the 3406B ended the 3406C was released. Mechanical was 5KJ07800 and up, I have never seen one of these. 3JZ16182 and up. The last fully mechanical 3406C was the 8PN. It is a totally different engine and parts do NOT inner change well with the older engine. Finally you had the last PEEC, 4CK0846 and up. It was a PEEC III and had a lot of VTU problems. That is I recall from memory.
We had a c175 16 drop 3 valve in one cylinder. Would love to see that on destruction of the week. But I think I would get in trouble if I sent that out.
Blasphemy! I wonder why not just run a C18 at that point instead of using custom parts, but some people like to be different. Now they need a big bore C13 that would be a C14 and you would have a full house.
@@AdeptApe id assume because the cost of a c18 crankshaft, with no core available. Plus c17 could be done as an inframe. Also the c17 should have a better rod ratio. Less side loading of piston. Pistons are made by mahle. Same as Caterpillar. Kinda a win for guys wanting more.
Love the videos, I’m learning a lot. I’m looking at buying an older truck and want a CAT. I see a lot of them that are advertised as a 6NZ. Some have the oil fill tube on the drivers side near the front of the engine and some have it in the passé side just in front of and below the turbo. Are they both 6NZ but different year models, or are the 2 different engines? Thanks 😊👍
Short version, too many changes to make a detailed video. Most of the time it's to improve the product or a emissions change is required. 5EK first full electronic 15 liter engine, 1994-1997, ADEM II electronics. 6TS same as above basically, 1997 ADEM II electronics. 1LW 1998 ADEM II electronics 2WS 1999 ADEM 2000 electronics Starting with 6NZ Cat change name to C-15. 6NZ last Cat 15 liter truck engine before stricter EPA laws. ADEM 2000 electronics, 2000-2002 MBN Last single turbo, smart wastegate and pilot injection if I recall. Not popular because of emission requirements. ADEM 2000 electronics, 2003 Name change to C15 BXS first dual turbo with ACERT technology, IVA and separate optional engine brake if equipped. 2003-2004 MXS second dual turbo with ACERT technology, IVA and if equipped with a Cat compression brake they are made together. NXS, same as a MXS. MXS ran out of numbers. 2005-2006 SDP, last 15 liter Cat truck engine. Most emission's regulations put on a Cat truck engine. Lots of emission related problems. 2007 to last build. You also have 16 liter engines, 5DS 1998, 1MM 1999, 7CZ 2000-2002.
3406 e I can't get it to prime up . All new fuel lines even put the main line from tank in bucket of diesel. I can vacuum it to prime buy then lose it. Any ideals?
If 1 were to put a C-18 in a show truck at 1,000hp would it be street legal and could it be done without heavy modification to the factory standard systems such as cooling intake and exaust?

Then with 4MG03600 fuel system camshaft and VTU was changed. Also JWAC I think was dropped and went strictly to CAC.
3406C Emissions is the biggest change I would say. A 3ZJ engine B or C model is the only truck engine that if you go by the parts book you will put the wrong nozzles in it.
3406C 8PN, is a odd engine and lots of changes, pistons, head, exhaust manifold etc. Again just to meet emissions.
Starting at 4MG03600 and to 8PN series. Numerous VTU changes as they had problems with carrier slipping, bolts backing out and such.
Starting in the early 3ZJ, era and other engine prefixes in this time frame the rod journal was increased, also other changes to the connecting rod. You have to get the article as it is a lot to type. Injection pump hsg changed and increased cam journal size.
The injection pump went from a single helix (early B models) to a dual helix (later B models) and the played with the check valve design. As fuel psi was increased for emissions a lot of fuel lines would break. If you didn't have the proper clamps they failed fairly quickly. Best to use the 8PN set up and I do some changes to it as well.
Emissions is the biggest so you have several piston compression ration and such, fuel system camshaft for timing and a few engine camshaft designs. Again a lot of typing and not worth it.
C18 engines were used in Finnish made Sisu Trucks. It was biggest engine in europe(or world) to be installed at stock production truck.
I would like to know more about all the “mechanical” 3406’s (A’s, B’s and C’s). Why are they so popular? Why is there a mechanical C and also a electronic C, but no D? Thanks for your time! I like watching all your videos and learn a lot from them.
Well the C engines were electronic, but with a mechanical fuel injection pump. A bad compromise in my opinion. I believe they went to the E model to signify Electronic more than a model progression as the engine changed tremendously from the C to the E.
A b and early C's were very easy to turn up. Last C's were bastard stepchildren because they were kind of mechanical and electronic. I think they skipped d because after the c model they went pure electronic.
@@rodneyward8357 3406 (now called A model) was a PCT, PCTA, DIT, DITA. (1973-1984) 92U prefix.
3406B at first was a 7FB, JWAC DITA, later ATAAC was added. As they ran out of serial numbers, the first 4MG's 1-03599 was still basically the same and still could be a JWAC.
Starting at 4MG03600 the VTU was the major change. And they went into the 90,000 serial numbers. Then they came out with a 5KJ and it was a 3406B, 1-07799. Most people get this serial number mixed up is the 3406 B 3ZJ, serial numbers 1-16181 is a 3406B. During the late 80's the dreaded PEEC was released. Electronic governor and VTU. You had PEEC II, PEEC II.V They started out as a 3406B 8TC. released next of the PEEC was a 2EK, still a 3406B. Last PEEC was the 4CK and it was a 3406B 1-0845. Another 3406B PEEC was a 5YG strictly a 460 HP @1900 RPM'S.
After the 3406B ended the 3406C was released. Mechanical was 5KJ07800 and up, I have never seen one of these.
3JZ16182 and up. The last fully mechanical 3406C was the 8PN. It is a totally different engine and parts do NOT inner change well with the older engine. Finally you had the last PEEC, 4CK0846 and up. It was a PEEC III and had a lot of VTU problems.
That is I recall from memory.
@@rodneyward8357 PEEC came in B and C models. Full mechanical came in B and C as well read below.
We had a c175 16 drop 3 valve in one cylinder. Would love to see that on destruction of the week. But I think I would get in trouble if I sent that out.
Please may you do the A, B & C
We would like to hear about the V12 CAT engines from you
❤️❤️
I would like a video on the 12 cylinders. And, what would need to be one to make one street legal for a 2002 - 2003 Peterbilt truck.
3406 a b and c 👍🏻 also 12 cylinders
A very Merry Christmas to you and your family. And basically Cat like most manufacturers have a gobbledygook nomenclature system.
Thank you Matt. Merry Christmas to you as well.
Why was the C16 and C18 only in short production and was it true that C16's were notorious for flywheel bolts coming undone?
IDP offers c17 kits now. C18 liner with a special piston height to wrist pin. To run on a 15.2 liter c15 crank shaft.
Blasphemy! I wonder why not just run a C18 at that point instead of using custom parts, but some people like to be different. Now they need a big bore C13 that would be a C14 and you would have a full house.
@@AdeptApe id assume because the cost of a c18 crankshaft, with no core available. Plus c17 could be done as an inframe. Also the c17 should have a better rod ratio. Less side loading of piston. Pistons are made by mahle. Same as Caterpillar. Kinda a win for guys wanting more.
Love the videos, I’m learning a lot. I’m looking at buying an older truck and want a CAT. I see a lot of them that are advertised as a 6NZ. Some have the oil fill tube on the drivers side near the front of the engine and some have it in the passé side just in front of and below the turbo. Are they both 6NZ but different year models, or are the 2 different engines? Thanks 😊👍
outstanding.....thanks
I would like to see some v series engine videos
A and B engine video would be nice.
Many thanks.
I wd u talk about D342 D353 engines
Was there a 5DS prefix for truck engines, and on the older cat electronic engine injector code can make a big difference in power
Another good car video.
Are the injectors of C15 and 3406 the same
Very fascinating info. Tell me how to build a monster b model
Have a lot of money.
Yes on the 12 cylinder series!
can you make a video explaining the difference between 3406E , mbn, mxs, and 6nz please
Short version, too many changes to make a detailed video. Most of the time it's to improve the product or a emissions change is required.
5EK first full electronic 15 liter engine, 1994-1997, ADEM II electronics.
6TS same as above basically, 1997 ADEM II electronics.
1LW 1998 ADEM II electronics
2WS 1999 ADEM 2000 electronics
Starting with 6NZ Cat change name to C-15.
6NZ last Cat 15 liter truck engine before stricter EPA laws. ADEM 2000 electronics, 2000-2002
MBN Last single turbo, smart wastegate and pilot injection if I recall. Not popular because of emission requirements. ADEM 2000 electronics, 2003
Name change to C15
BXS first dual turbo with ACERT technology, IVA and separate optional engine brake if equipped. 2003-2004
MXS second dual turbo with ACERT technology, IVA and if equipped with a Cat compression brake they are made together.
NXS, same as a MXS. MXS ran out of numbers. 2005-2006
SDP, last 15 liter Cat truck engine. Most emission's regulations put on a Cat truck engine. Lots of emission related problems.
2007 to last build.
You also have 16 liter engines, 5DS 1998, 1MM 1999, 7CZ 2000-2002.
Hey what’s a good oil pressure cold and hot for a 3406b thank you brother for your videos
Cold idleing 45-50 , hot 1900 rpm's 60 -65 , idleing 35-40
3406 e I can't get it to prime up . All new fuel lines even put the main line from tank in bucket of diesel. I can vacuum it to prime buy then lose it. Any ideals?
If 1 were to put a C-18 in a show truck at 1,000hp would it be street legal and could it be done without heavy modification to the factory standard systems such as cooling intake and exaust?
Do you have a video for C 16 crank sensor
So a marine c18 in a long nose large car is the way to go!? Got it!!! Ok, shoot us that v12 video now boss!!!
The C18 is actually 1,106 cubic inches. 5.71 bore x 7.2 stroke.
