I have a c12 myself 2001 2ks and my rollers also went out and ruined the cam. Mainly the exhaust side. I also had the head and valves tested and all the exhaust valves needed to be replaced. This was after 400 k rebuild. I bought the truck shortly after the rebuild. One of the rollers broke in half and we found peices in the oil pan. Several other rollers were bad as well all on the exhaust side. The engine was actually still running and getting good mileage but would not hold a valve adjustment. After about a couple of months it would be out of adjustment. Wish I would have had you as my mechanic.
Love those c12’s. Unfortunately the lifter follower issue was its #1 flaw. Solid little engine with a great power to weight ratio
Your right I had one in my 01 freighliner century that’s exactly what failed in mine but it did have 850k before it did great little Eng though ✌🏻🤙🏻💪🏻
Is it a big job to fix?
Unfortunately if your not sure removing the oil pan is the best way to see the cam. Any time the head is off and you have the 115 beginning part number EUI lifter. You better replace them all and put the 202 part number in them. Seen numerous 115's fail, more than likely the part number begins with 115. If your not replacing the set, take each one and make sure the pin won't spin. On some they have a arrow on them if I recall. Make sure they are pointing up.
Also while the front cover is off, torque all inner plate bolts you can get to.
I have had luck on the bottom radiator nuts, just taking a impact wrench and moving it side to side and remove the nut without holding the head with a wrench. I also put them back on that way. Takes a few minutes, but I don't have to stop someone else working.
I’m still in school… your videos help so much! We should be finishing up our engine rebuild today. A week late. We bent one of our push rods. 🙄 and timing the valves sucked so bad!
Thank you for you videos! I feel so much better that I actually understand what your talking about!😳 wasn’t sure I could keep up with class.
The best way to see if your on TDC of cylinder X, is to look at the buddy cylinder and see if the valves are in overlap or close to it. Depends on camshaft design, duration and lift.
First of all, thank you for these meaningful videos. Secondly, I hope that the video will be accompanied by what you say in the form of sentences below the video so that we can understand more. Greetings
Closed Captioning (CC) will help you if you turn it on (I think it's the middle/3rd icon on mobile controls). Desktop will be different. These are auto generated but most times close to the truth...
I learn so much info from your videos. BTW, if you ever need to tape something off and want it to come off clean without residue, try gaffers tape. It's available in multiple colors. Keep making awesome content!
I like your approach and experience
Am guessing it's also distraction of the week, all in one video. Thanks for the video
I grew up with Detroit and Cummins engines in trucks. I've driven a few cat powered trucks. 3 B models and a C15 Acert really love your videos. I work on my own stuff and I really enjoy the Cat content. Keep it up
Your videos are as informative as my astrophysics class. 🤣😂🤣 I can't even spell astrophysics .... But you still make a great video and I always learn something.
Thanks for watching Dan
I feel your pain on the radiator bolts. Those suck getting a wrench on. I started welding the bolt heads every time I have one out now
I had to pull my c12 cam last winter. My cat manual told me to use wires to lift followers. So I used a bunch of shirt hangers.
Another interesting video from my friend the APE! I hate to see you having to work so danged hard but I know you prefer to get your hands on the hardware. Keep warm and keep up the great videos.
Hi Larry, no problem working hard. I'd take a busy day over a boring day every time. It's supposed to be a low of 1 degree here Wednesday so please turn the heater up for me will ya.
@@AdeptApe no problemo good buddy. Don’t wanna turn it up too much, it’s gonna be 80 here tomorrow. 😎
Great videos as always! I picked up a truck with a c12 not to long ago. Hopefully doing a rebuild on it. Want to do it myself! Good info thanks
Excellent video, thank you for posting.
At least that one cam out job does not require removing the whole engine first like so many engines today
I really love your videos, wish I was younger I'd follow in your foot steps
First thing I do with any HD diesel is...take to my trusted mechanic who actually knows how to do a real rack adjustment/valve calibration. Drive it for a day then change my oil, add a gallon of Lucas, change all my filters, flush radiator, flush power steering and flush transmission. Did all that with my ISX and C12...currently driving the C12 with a straight pipe...changing rotella syn blend oil every 15K and air filter every 6 months. I'm getting over 8mpg loaded and over 9mpg empty! I believe that must people don't know how to be good semi truck owners. Must C12's go bad because your suppose to do a rack adjustment about 10 to 15K after a head gasket or overhaul...basically first oil change after and must people don't do that. After that you should do a rack adjustment every 150 to 250K miles...so if your truck has 500K it should already have had at least 2 rack adjustments! Don't believe what the previous owner says...just follow that method and you will be running good for a long time!😉👍👍💯💯
I really enjoyed your video I need to know more about older C-15 cat
I’m not likely to ever have to replace a camshaft in one of these engines - but if I do..... well, I’m set!
interesting though ey?!
Thank you for the content, as usual. I'm having a bit of trouble with my C12. Low oil pressure indicator, engine control light. I'm getting oil to the filter and can't locate the oil pressure sensor.
I see your mate's back.
Hi, appreciate your videos a lot, big thanks to you
I know you need donations not big thanks
I would have liked to see the cam removal tool in more detail. I watch a few guys who rebuild these, but they're usually replacing the cam bearings anyway. As always, I enjoy watching your videos
The cam bearings were replaced during the rebuild, but this is a warranty repair so they were inspected and reused. They were in good shape.
The cam removal tool is just a piece of aluminum that is the same diameter as the cam and is screwed onto the front or rear of the cam. It bridges the gap between journals so that as you pull (or insert) the cam, it doesn't fall out of alignment of the bores and keeps you from nicking up the bearings.
Josh has a video showing the cam tool in detail, about 6-8 months ago I think.
The same problem happens with C13 engines. I’ve seen quite a few of them, including blowing a hole through the block and into the ECM. Lots of carnage. Luckily the C12 is a pretty robust engine and has few other problems.
Hello, the video is very interesting, a question, teacher, I have a C12, the problem started due to contamination of the diesel in the oil, 5 sets of injectors have already been installed and the problem continues, the diesel pump has also been installed new fron caterpillar if you Give me some information that could be I would be very grateful.and thanks for your information, I'm learning a lot
That cam removal tool was interesting.
Funny you know ! I've seen.this a lot on trucks but not so much in off road machinery applications, I have postured a theory that too often no6 valve set does not get done always as it often is harder too do and guys take short cuts
Thank you.
Another great video!
Was those cam rollers the updated version for the c-12, because the rollers in the original version was not as wide correct?
Great video
Do you install new cam bearings when you put in a new camshaft? Do you measure the new parts to check for oil clearances if you do? I need to do this project this winter. Thanks!
Great video.
I was wondering if you can remove the cam without removing the cylinder head on a C-12?
Been there done that on mine!
Great video ..
Hey Joshua how many miles did that motor have on it. Great video
Good Video
Do you do any work on Cummins? I work in the truck shop at a cat dealer and we do a pretty good bit of work on Cummins between buses, our service trucks, and yard trucks
Do the cam’s ever damage the block in the C12?
Is the C12 a pretty good engine? I have looked at several motor homes lately that got the C12 with the 505hp RV tune in them. I only drove a truck for a short while with a 465hp C12, but that one was pretty rough and not a good candidate to get a decent opinion on the engine.
Hi , I’m a new subscriber. Im buying 2004 peterbuilt 387 C15 engine, im just wandering if this truck can ran ELD? Love your vlog. Thanks
My c12 has a bad oil leak where the power steering pump bolts to the engine do you think it's a crack in the front cover?
Have idea were I can fine. Steering wheel. Pump for 3406b.
I had a injector solenoid blow apart and wipe the cam out on a c13
I loved the c12, nice turbo, super loud jakes even with a stock muffler…way louder than a c15. Cons: oil burner, poor fuel economy, liked to throw rods. What was the issue with the c12s throwing rods?
Instead of snap rings in the wrist pin it has a plastic plug you knock into the piston. Those plastic plugs wear out and the wrist pin slides over and it all crashes.
@@careykuhn9174 did they update that design? Plastic? Seriously? Who thought of that?
Had several c12. Never any issues with them. Got good fuel mileage. Never used oil. Best electric cat engine built. I overhaul several all in the 900k mile range. Only thing I didn’t like was the brass pin in rocker. That’s what got cams
What brand of camera and which model do you use and prefer??
Nice , any advice on a 3126 with square heui pump, the heui pump won't build more than 500 psi and already checked the ECM, checked the wiring from to ecm , replaced heui pump, and for some reason the heui pump won't build pressure, voltage on the heui solenoid from ecm is about 7v , l checked on a running truck and solenoid voltage was 3.6 , any sensor or something that would have to check?
5:06 Thats what she said !
What does cat recommend for power steering fluid
Did you say you are now the shop foreman? If so congrats!
I'm just a lowly hourly minion, scrounging a living together and fighting for the scraps with rodents and large insects. I'm actually paid fairly, but I'm not the supervisor.
Hey buddy C 15 spt and c 15 mxs wish one is better engine ?
Does it have drive tires on the steers?
Is 90k gross too much for a c12 to pull regularly?
No, but it all depends on How it is Geared and What Transmission it has. What Gear Ratio The Rear Axle is, and the Transmission are your 2 Main Factors.
Nice work josh. Question about a 3406c truck motor. Is there anyway I can direct message you or message you on another platform.?
adeptape@yahoo.com
How much a job like this cost
How much c15 will coast me if I wanna rebuild the engine ?
With OEM Parts ?
And where are you located ?
If I wanna bring the truck to you ???
Send me an email at adeptape@yahoo.com
How about a 3126 or a C7
Has anyone seen an ecm fail in a way that the engine will still start but there’s no throttle response. I’m missing my check engine light with key on engine off as well
My c12 throws engine light in the middle of pulls empty/loaded and does it randomly even when cruise is set but its only on briefly then goes off sometimes blinks once comes back on then goes off... that being said its done this for a year now and my boss has said its always done it never any problems but I'm buying the truck now and I'd wanna look into it any opinions would be appreciated TIA
Camshaft sensor and eventually gonna need a cam
@@geauxtigers70714 thanks brother ill talk to mechanic about it...
😎👍
Love your videos!I need some help!!
2000 c6500 3126. I had low voltage to pin 70 on the ecm. In trying to correct that I have now earned no voltage to thin 70. Missing check engine light and intake heater lights. I jumped 12 volts to the pink pin 70 wire and the engine starts and the intake heater light starts working but I have no throttle response and the check engine light is not lighting up with key on. It’s my work truck it’s zero degrees I could use a direction ty!!!
You need to list your engine serial number as it will help guide what to do. On your 70 pin, J1P1 truck side, unswitched battery power is 52 and 53, key is 70. Sometimes you have to load the circuit to see if the system can carry the load. Battery negative is 65 and 67. Pin 5 is system common ground to other systems (including throttle, pin B) on the truck. Pin 4 is your 8 volt supply to the throttle sensor pin A. And pin 66 is your throttle signal wire pin C.
No throttle could be failure in the circuit, sensor, ECM or if the personality code is not married up to the ECM or called interlock code. The engine will only idle. You can make a bypass harness using pin's 52,53,and 70 battery positive. Pins 65 and 67, battery negative, to a good power source. Does not have to be battery on the truck. Use throttle pin call out 4,5 and 66 in the bypass harness. Start the truck and see if it will throttle up. You will now know if you have a ECM problem or a truck problem. Make sure you put a fuse in your power supply. You will need a 70 pin J1 connector truck side, some pins, wire and a good throttle sensor.
Low voltage to pin 70, you could have a dirty connection some place, failed key switch, wire rubbing, etc. I would check power at the key switch going in and coming out. Would not hurt to clean all battery cables. Any time you troubleshoot something like this, in this case a electrical problem. You can start at battery to ECM. Or ECM back to battery. However if you can start someplace in the middle, (key switch) you know do I need to go left or right.
Thanks for your response. Are you familiar with a stop lamp switch interface module, reading my schematic that’s where pin 70 power starts in this truck. My problem is i don’t have switched power going to ecm. I replaced my ecm because it failed, it ran fine but while testing before replacing I noticed during testing I was only getting 8 volts at pin 70 on the ecm connector a as bud was worried thats what took out my last module. Shoulda left it alone smh
@@mikehagerty8126 I do not, you have to see if it's a truck problem or ECM.
It’s a truck problem. I did the fuses jump wire in the dash running down to pin 70. Truck starts and idles great when I do this. No throttle response tho 😂. I drove this truck 100 miles home after replacing ecm. Like I said I had only 8 volts making it to the ecm on pin 70. So I decided to cut in a 12 volt fuses source and that’s when I lost my 8 volts I had and lost throttle response. Now there’s no power to put it back the way it was. Nightmare!!! I had it working😂😂😵💫
@@mikehagerty8126 My motto is better you then me. So you do not have 8 volts coming out of the ECM for throttle?
took my c12 to the shop to replace cam and rollers recently and costed me 16k nzd
Damn...you could have gotten a whole rebuild and brand new original clutch installed...parts and labor for 16K! What shop suckered you like that so nobody gets got like that anymore?? 🤔👎👎
That’s a pretty standard rate here in New Zealand 🇳🇿 it’s because we’re so far away from everyone it costs more, locating and shipping a cam shaft was hard enough! we had to get one in from Australia 🤦♂️ having said that a full rebuild and clutch like you say would cost $25k-$35k. Good to be a diesel mechanic here I guess 😮💨
How many times did the young Guy borrow tools
Not as much as the last video and he tried to stay away from the camera this time
@@AdeptApe Are all of your Hand Tools Cornwell? I have been thinking about Buying a Couple of Gliders that have Cat C-12’s in them for Local Work. What’s your Overall Opinion of this Cat Motor?
MX13 cams failing right and left
Eww saw one like this before,, owner didn’t want it fixed due to age and hours on truck
Bronze bushing on roller not a good idea ..
Must be in a dump truck,most dumps have fuel
Coolers.
Why? Do they get extra hot with the PTO equipment around the fuel tanks or something?
👍👍👍👍👍🍺👊
Understood nothing
FIRST!
You are correct!
