Thanks for putting these videos, you have really helped me in working on c7 systems especially the ard/fuel systems.
Thank you for this video, and all of the rest of the info you've put out. It has been a great help. One thing on timing - i set a C18 backlash to 0.014, and was about half a tooth off. after puzzling over this for a ridiculously long time, i finally realized that the backlash will affect the position of the cam timing mark. when i set the backlash to 0.005/006 (spec: 0.014 ± 0.010), my cam timing marks lined up at TDC as the pin slipped in, just as they should
Thanks for sharing, this is what I was looking for!
I helped on a cam job for a cat years ago. Made me really like Cummins.
This was a good video. Plain and simple
Really Like the intro
Great as always, Josh! Thank you for sharing you knowledge!
+ed eduard Thanks for the kind words, I'm going to try and get to 100,000 subscribers.
Adept Ape what are your thoughts on a marine cam in replacement of stock 6nz cam?
+tnsportsman21 I wish I did more work on the hot rodding side of the industry because I get a lot of questions about it, but I never really go outside of stock components. The C15 can definitely make a lot more power. Look at the C18, basically a C15 with a little more displacement, but has 900 HP easily.
Adept Ape I just put a aftermarket borg Warner s400sx4 turbo on and was just looking for something else to get a little more hp at a reasonable price. Do I need to do any reprogramming for that turbo you think? Doing an overhead now and new rod and main bearings. Just wasn't sure what a stock engine could handle with that marine cam and or bigger injectors. Thanks

Thanks for sharing your info and time ! Great to see you reached out to help jay too! I’m not convinced on switching to a single turbo setup is right for him but what do I know lol! I wouldn’t be able to work on it here in upstate ny ! Emissions tampering! Thanks again for video 👍Happy New Year!
+Black Smoke I don't recommend going with aftermarket components or messing with the software, but a lot of guys like modifying their rigs. I don't deal with the aftermarket either since Cat frowns upon it, but I was happy to answer his questions.
Thanks! I agree I let the customer make their choices! I only give info and advice but at end of day it’s up to them. Love all your videos keep them coming!
Thank you sir
I'll make one of these!
please can you help me, l want to know how can install and disassembly cam shaft for C 18.
Its actually really easy
So good.
@adeptape are there torque specs and sequence for replacing peanut cover to stop leaks?
Rebuilding 2006 c15. What do you need to go from the 550 to 6-625 hp different than just back original.
Good info, thanks!
+Sebastien Hache Thanks for watching.
Thanks sir
So beautiful
Thanks this vdeo
Great work thanks for sharing
OH, nice hat !
Thanks
Thank you I have leak will that seal help it out
So I removed the gear not knowing it had to be pinned for timing. I haven’t removed the 3 bolt plate behind it. Can I reinstall the gear and then pin it?I will be switching out the head.
I’ve just did an inframe on my 3406e and I’m having an issue with cam, thrust plate, cam gear. Once i install the seal plate, the adapter then the retaining plate I can’t get the cam to turn anymore by hand. My adjustable idle gear is off as well as I just re sealed the front housing/ gear assemblies so nothing is restricting rotation there and I just have cam in the head nothing else. If I just barely touch down the three bolts holding the plate in place it will still turn. If I tighten them it freezes any rotation of cam I can almost finger tighten them and loose rotation. I’ve even tried putting the cam gear on to make sure cam is in right spot still can’t turn it. Any knowledge on the matter would be much appreciated.
Brandon Portman you ever figure it out? Had the same problem the cam bearing was out just a little hammered it in a little good to go
I hated those T40+ screws with a passion. If they weren't rotted out they were already chewed up. I always put new ones in after wire brushing most of the Loctight patch off. The ones on the back of the head were worse.
Nice
hola amigo. un cat 3406E me queda un poco recorrido el diente y no lo puedo sincronizar exactamente. es normal?
I like your special toool
Do you have part numbers for the o rings you replace?

Hello, would you expand on the warning Cat has about being one half of a tooth out on the cam gear timing mark to the front cover mark please. I have a MBN in my shop I have had the front cover off of to replace the cluster gear and idle gears. (Code 22-11 primary to secondary sensor signal calibration) After assembly with crank pinned on tdc and cluster gear aligned to crank, this should have been tdc#1 compression. Adjustable idle at 0.014" the cam gear timing mark is a half a tooth off of the mark on the front cover. So I have removed the idler and rotated the crank forward one revolution to tdc and pinned. Installed idler, and still the cam gear ends up on ether side of the cover mark, a half a tooth off.
Please explain how Cat says that tdc1 and tdc6 are different, when I have controlled the cluster gear timing mark as instructions in assembly and disassembly direct and yet I'm a half a tooth out.
Thankyou
A 22-11 code means your out of phase. You don't move the crankshaft leave it alone. Most of the time when your off that much, your head or block has been milled. I pin the flywheel on TDC. Best to have the rocker arms off, put the cam gear on and torque to spec. I than remove the cam idler gear and use a modified gear I made that is cut out on both sides. With the stub shaft slightly loose, I pin the camshaft gear dead on the timing mark. I take a set of feeler gauges that I cut both sides down and check my lash. Make sure you turn the cam gear to the right when you take the slack out, as that is normal running rotation. Your stub shaft also has a hole in it and you can put a bolt in it to start at center if you like. If my lash is 0.014 plus or minus 0.010 you are in spec. I than snug up the nuts and bolt on the stub shaft. Remove my adjustment gear, install the running gear and recheck my lash. Have seen it change some with the running gear. If lash is still good, I take gear off and torque all hardware, put gear back on and finish assembly. If your cam gear is timed and your lash is not within spec you have to make an adjustment. At this point I am not concern with my timing mark on my gear. I can always move the cam back to a timing point. What I want to know now is. How close am I to a full cam gear tooth and my lash be with in spec. Turning the cam gear to the right decreases lash. Turing the cam gear to the left increases lash. Cat does not like it on the tight side. Sometimes I will put a 0.007 feeler gauge in if I have to go in that direction and let it bottom out. Once I get it where I like it, I take adjustment gear off and turn cam gear if needed to timing point and torque, recheck etc.
Adept Ape. I changed the head and am having a time with the timing. Is it possible that the flywheel isn't timed properly? When it is pinned #1 and 6 are not at TDC. Any help is appreciated. Awesome Channel
Hey man what did you manage to do? I have one exactly like this ,I'm thinking either removing transmission and align the transmission or just "winging it" by "feeling" the TDC.
Had one as well,someone misaligned flywheel. Brakesaver model.
Does SIS not outline all this?
Any tips as to preventing the crank and related gears from turning while the cam gear is torqued?
He showed you, he pinned the engine with bolt
Pin it
Hey question for u does the camshaft gear stick out a little past the adjustable idler gear?
It does just a little bit.
That cam gear torque has been reduced. Check your sis info. They had trouble recently with the cam nose
Nice we are in punjab

+Adept Ape Your videos are great, simple and easy to follow. Any chance you could do some 3176B vids (guess which Cat I own). I'm thinking they're not that popular which makes it even harder to find 3176B info/help online. It's all helpful though. Thanks!
+Dennis Gravett Hi Dennis, you don't see the 3176 very often. The C12 is based on it though and they are fairly common. I don't think I've worked on one in maybe 3 years. I usually make videos about items I am working on, so probably won't be making a video on one in the near future.
+Adept Ape Thanks for the quick reply. Bummer, I figured that was the case. Oh well, I love watching your videos anyway and always learn good stuff. I selfishly hope a poor sick 3176B comes your way that needs tons of service and repair. I'll stay tuned....
Dennis Gravett 3176, at first was a 2YG, next was a 7LG, had three levels of them, 07499 and below. 07500 to 15999 and 16000 and up. Then came 3176B 9CK prefix. They was better than the other two. The 2YG's was a nightmare. No matter which of these you have the outer and inner front covers are prone to crack. You have to have updated supports, A/C and Alt. This helps but no guarantee it stops. Also power steering gear and air compressor drive gears wear and causes problems. Again updated parts are needed. If you rebuild engine, spacer block needs to come off and replace seals under it. Extra work, but saves you a big head ache down the road. Flt trucks on the 2YG's and 7LG's the fresh air line was not routed properly and a hole would get in it. Water would than run down the line into the TDM, ECM and PM and destroy all three. I wrapped a new line three coils around radiator brace to trap any water. On the intake manifold moisture would inner the system and get into the boost hose and destroy the TDM. A stand pipe (now obsolete) was needed to prevent this. The electronics on the 9CK was like the 3406E 5EK and much better.
Hi I am rebuilding my 3406E 1LW. The book my buddy has says .0085 + - .0045. You’re saying it should be .014 -.024. Did cat change something. Any insight would help. Thank you.
Cat had to change lash as heads was being machined during this time frame. Causing cam and crank sensor to be out of phase.
The min spec is .004 and max is .024. I don't like the .004, as gear whine can occur. Now all heads are new.
Is yours the 605hp like mine she came out of Safeway grocery truck hauling doubles over the Rockies powerful as heck just bad oil leak at front housing
✌
السلام عليكم بغيت نعرف كيفاش يركبوا لي باك ديال لي زانجيكتور ديال النحاس ديال 320 دي كاتربيلار هذاك المونتاج ديالهم لا ماشين باش يركبوا خاصني نعرف كيفاش دايره
C a t generator c15 Ra diator inside oil coming what problem.
My truck is making rattling noise behind the cam gear houseing
what is the purpose/proper name of the 8 count of "free floating rollers" that are built into the camshaft gear?
I work for a Caterpillar dealer in Florida, and have overhauled more c15's than I can count. Currently in a company funded class and this question came up today in a powertrain class of all things, from my instructor. I couldn't come up with an answer for him. any help would be appreciated. please advise.
@@chancebedore2431 The camshaft drive gear has integral pendulums which act as a vibration damper for the front gear group. These pendulums are designed to counteract the torsional forces from the injector pulses. This eliminates vibration and noise. The engine also runs smoother at all operating speeds.
Hi! usually why is it necessary to replace this gear?
That's what I want to know because it seems like one of those components that's indestructable & would outlast all the other components.
Oh nevermind lol, the next video in time is about camshaft gear backlash...so the teeth wear out over time & that's of course problematic roflcopter.
Hi, where are you located?
Love the Ape but the spiral in the beginning is dizzy/silly.
Can you show us how 3406b engine timing advance mechanism function thank you
The 3406B had two types, basically of VTU. So which one do you have?
please cat c15 full riming give me
What’s the torque they need to be at
180 for pounds. Thank you
I used to just use a rocker shaft bolt
It's just a finger tip saver part# Fts001
Lol
What would cause the bolts to sheer off on the plate on the front of the cam gear? This is the second cam gear this week that it did this too. Please help
Are you talking about the plate that holds the rollers in? If you haven't fixed it yet that is.
@@nickforgey509 yes
@@margaretmurray3079 Is it damaging the peanut cover when it happens or only the bolts? Also your engine serial number prefix could be helpful if you have it.
@@nickforgey509 5EK and totally blew the peanut cover apart
@@margaretmurray3079 Seems like the cam might be walking out. With the cam gear off there should be a plate with three bolts in it. If some of the bolts are missing or if the plate is missing it could be your problem. It's the only thing that holds the cam in the head besides the rocker arms. Its definitely not a common problem.
Is this the same for a 3406c?
3406 C is a mechanical engine using a pump and line system. Some 3406 C's was a PEEC with electronics added to the engine. But still had to pin time the pump to the engine via the hydro-mechanical VTU or the hydro-mechanical electronic control VTU.
You know what Cat stands for CAN'T AFFORD THAT.......
C-32 e o mesmo procedimento
T40+ ? 3/8 bolt welded to stupid bolt. Replace with normal bolts
If u remove the head will the cam stay in the head
Yes.
My peanut cover is T27 plus it's a 1lw 605hp must have used different ones on that 1999
cummins isbe engines please
All he does/works on it's CATERPILLAR.
I have a 3412 generator that has the problem of falling frequency and speed

T40+.... Really REALLY...
