20- 2012 Cummins, Single Cam, ISX, Rocker Arm Installation And Valve Adjustment

[@ajvillar2467]

What about running clearance?

[@TerraFirmaX]

What about watching the whole video

[@ajvillar2467]

​@TerraFirmaX I did you obviously didn't he stops at adjusting the exhaust Brakes but that's not where you stop you're supposed to measure the running clearance after, if it doesn't measure within spec you have to loosen the rocker arm capscrews and twist the rocker shaft back or forward depending on if you have too little or too much clearance which is all shit you would know if you've ever actually done the job by the book

[@TerraFirmaX]

@@ajvillar2467 lol. Well I did the job by the book so I guess one of us is full of shit. Thanks for watching, I don’t know why you are watching since you know everything

[@MechanicTechnicianRepair]

hello teacher why is there to replace the rocker arm

[@TerraFirmaX]

Because the rollers are a wear item and we put a new cam in so we needed new rollers on the rockers.

[@MechanicTechnicianRepair]

oh ok grasia maetro

[@youtubeisawesome2487]

L10, m11 ism n14 isx all have .14 on intake and .27 on exhaust valve settings for lash, .09 and .22 are for isb isc and b and c model cummins, and i am almost certain the ntc 855 also had 14 and 27 valve lash settings, although it has been a very long time since is set stc and ntc 855. for anyone following this series of videos get the book and follow the procedures for all engine repair from cummins as things change all the time,

[@TerraFirmaX]

My specs WERE from the book.

[@youtubeisawesome2487]

i have set 100s if not a 1000s of isx overheads you might want to recheck your book, tight valves will burn the valves eventually and wear out the camshaft again

[@frankbertola3662]

You have a good voice and manner clearly explaining the tech & spec and all topped off with good camera work plus some good humor. Thankyou

[@TerraFirmaX]

Thank you sir.

[@donaldjleslie5956]

quality control is good,

[@bryanrodriguez8789]

I thought the valve clearance was .014 intake and .027 exhaust and .276 jake brake. Let me know if that is correct.

[@TerraFirmaX]

I followed Quickserve online

[@jalopyhotrod6394]

Cummins been 14& 27 since for ever

[@jalopyhotrod6394]

Also looks crazy tight on Jam nuts wow How’d it run

[@downunderjuice]

Rocker shafts are front and rear dependent.

[@TerraFirmaX]

yes they are

[@downunderjuice]

@@TerraFirmaX Great video's. Where did you get all your parts? Just fucking with you.

[@SnarkyGoat]

Awesome, so close now...!

[@ahweeautomart6085]

Are you sure that the valve clearance is right i just did a 20014 and the adjustment is 14 for the intake and 27 for the exhaust

[@TerraFirmaX]

According to Quick serve on line and the valve cover

[@ahweeautomart6085]

What year is the truck you are working on, I work on Cummins everyday, those specs seem to be wrong

[@TerraFirmaX]

Ahwee Automart 2012 as stated in the title look it up on quick serve it’s on there and it is also on my valve cover

[@TerraFirmaX]

Ahwee Automart you were getting me worried so I pulled over and double checked. Those specs are indeed correct. I do appreciate you giving me a heads up.

[@sddhydcedheec]

I put rubber bands on my rockers to keep them from flopping around on me when I'm installing them

[@TerraFirmaX]

Smart Idea

[@jillshomesteadexperience6706]

Great job hun

[@TerraFirmaX]

[@dumitrup7939]

Hi sir, are you sure, valve lash to be 9 with 22 thousandths, Thank you

[@extremegardening8440]

Man, you deserve a lot of credit for doing this yourself. Amazing 👍 what did you say would come out of the exhaust manifold?? . Lol. Now that’s funny.

[@TerraFirmaX]

crap from the assembly process, like all the oil. don't want to plug the DPF

[@deeb1504]

@@TerraFirmaX great video. How much would this job cost with parts and labor?

[@jiml9971]

I noticed you adjusted the valves and did not torque the lock nuts because you don’t have a crows foot. The way I’d do them is tighten them about half of the torque by hand then use a torque wrench with a deep socket. I 99 percent of the time I do this it’s a perfect setting. It’s just the way I do them hope this helps you

[@TerraFirmaX]

That is exactly what I did

[@txmuddigger]

I don't know why I'm seeing all your videos all the sudden but I'm glad I am. Weird how that works, I specialize in Detroit Diesel but have been seeing a LOT more Cummins over this past year. And then I start seeing your Cummins videos out of nowhere.

[@TerraFirmaX]

Well, hopefully it helps. Thanks for checking it out
