19- Cummins ISX CM2250 Engine Base Timing. We Are Getting Close

[@jpkrause]

Working on big diesel engines isn't for the faint of heart. I enjoyed watching

[@TerraFirmaX]

Thanks for watching!

[@jiml9971]

Don’t feel bad about dropping the feeler gauge in the pan ive been a diesel mechanic for 42 years. And I’ve done far worse things over my career ! Chin up you are doing things really well

[@TerraFirmaX]

Thank you very much. The truck is running down the road and doing well

[@lvasqu]

Wow what an amazing video. Thanks for all the knowledge. It was very helpful ! Looking forward to more !

[@TerraFirmaX]

thank you

[@cmcgill8832]

Honestly if it was mine I wouldn't bother with the feeler guages in the pan its not like the pickup tube can suck them up bc of the strainer on it,and they arnt big enough to stop the flow up. Odds are you can get it out threw the oil plug anyways. But thanks for these videos, I've worked on diesels since I was a teenager and have always hurd horror stories about debris geting in the oil hole when pulling a isx head. So I've always avoided them lol but we got a guy wanting us to swap a head out for him and these videos you've made are really helpful in familiarizing with the isx,thanks

[@txmuddigger]

Ever heard one run with excessive gear lash? Same sound as a bad throw out bearing.

[@roberttuttle5963]

laughed like he&& when i seen that. cause i. did. that my self when in was checking a idler myself. sounded the same the oil. pan was full of oil. had to. drain out and took. an extention magnet went thru the oil drain hole found the feeler blade set and got it out thru the hole after that. i. put a long medium tie strap on my feeler blade set it wouldn't fit past the gears after that just a hint if you would like. when you torque the idler nuts to. 22 ft lb. mark the plate with the white marker then the bolt 1 hex back then turn the bolt and align up. the marks you made that way you have a good indacater when to. stop. thanks for the video. brought back some memories i retired from cummins engines after 40. years shop tech and road tech tmi

[@SnarkyGoat]

It's coming along great 👍

[@TerraFirmaX]

CEB Homestead thanks

[@jillshomesteadexperience6706]

You’re doing a great job hun. Keep up the good work.

[@TerraFirmaX]

Thanks babe

[@DHVVLOG]

Woo. Good video, new friend here. Always full supported, best wishes for you. Thank you !!!!

[@TerraFirmaX]

Dhv Family thanks

[@alexislemus2234]

Thank you 🙏

[@TerraFirmaX]

Thank you

[@youtubeisawesome2487]

the lash is .010 not .004, you should also cut your feeler gauge down, they are too wide to fit between the gears without bottoming in each gear, also hit the gear(ring the gear like a bell) after torquing the bolt and retorque do that until the bolt doesnt move any more, usually take three or four times

[@TerraFirmaX]

Thanks for the tips, but the feeler gauge did not bottom out and QSOL Spec was .004

[@johanperez1689]

The most important spec is probably making sure that your using the correct feeler gauge at .010" for this scissor type lower idler gear vs. The 0.004" feeler gauge for the solid type lower idler gear. Anyway i guess better late than never..... NO!!!!! GET IT RIGHT THE FIRST TIME!!! WHO WANTS TO CRANK THE THE MOTOR AND HEAR A NICE GEAR TO GEAR VIOLENT WINDING NOISE, ALL TO BE DEMORALIZED AND NOT TO MENTION THE HEART BREAKING RE-DISSASSEMBLY!!!! THX. BUD FOR THAT SPEC CHECK!!!!

[@TerraFirmaX]

@@johanperez1689 100,000 later still running fine soooo.

[@Theheavys]

@@johanperez1689it’s .004” solid or scissor, maybe you have an outdated service manual brother because current service manuals on qsol is .004”

[@jgist909]

If my harmonic balancer doesn't have any visible markings how do I know where to pin the engine at the bottom

[@TerraFirmaX]

You have to sand down the balancer. The marks are there guaranteed. When you find them, mark then like I did

[@ourselfreliantlife]

Dang Warren! Sorry you had to take off the fuel pan again. Stop dropping them gauges. 😬

[@TerraFirmaX]

lol, okay

[@CanhNguyen-xw4qv]

Thanks ❤❤❤❤❤❤

[@hd93scooter]

Nerve racking I tell ya!! Good deal👍✌️

[@TerraFirmaX]

yes it was. I was so pissed about dropping the feeler gauges into the oil pan, I couldn't even cuss. lol

[@hd93scooter]

The Arizona Homestead Project you’re a better man than I... I would have been cussing and throwing shit!!😂😂😂

[@TerraFirmaX]

@@hd93scooter lol, yeah, that's why I said "shut that off" lol, I had a few choice words.

[@johndavidstutts]

Think cummins requires 5 thousands lash. Looked like it had scissor gear. That needed to be unloaded. I also never use the loctite on cam gear. I use a brass drift and smack the cam gear bolt and re torque till it holds. Never had one slip. Runs quiet too.

[@TerraFirmaX]

AWESOME, And I don't think, I know for a fact what Cummins called for because I got all my specs directly from Cummins. Again, Cummins also requires the use of LokTite on the camgear, Not smack it with a brass drift and torque it till it holds.

[@johndavidstutts]

@@TerraFirmaX I actually replaced a gear housing on a x15 TODAY the 3rd I've done in 4 weeks. Just saying what I know, and info from QSOL. The deleted loctite is my deal. I wash gear and cam with electric parts cleaner and put it on by setting the gear with a drift. Never had a come back. I have seen a cam gear slip with the loctite. Just my two cents.

[@TerraFirmaX]

@@johndavidstutts WELL, QSOL is where I got all my specs, But mine is not an X15 it's a CM 2250

[@johndavidstutts]

2250 lash is 0.004 per QSOL. I got 2 gauges I use every time. Thought they were 0.005 but they are 0.004. All single cam engines are the same spec. Not arguing, just saying. Good luck

[@salahahmed8272]

great job thank you

[@TerraFirmaX]

Thank you sir. I appreciate your comments

[@hearshotkid2216]

Question about the fuel pump idler gear, I installed the front gear housing and the center hole isn’t 100% lined up with the dowel spacer on the block. All my bolts are lined up with their holes.

[@davinbonyonte2546]

Good job.

[@TerraFirmaX]

Many many thanks

[@carlosduprey1778]

You can use a screwdriver with magnets

[@orestesreyes9161]

Hello can you please tell me what feeler gauge measurement that was

[@strikeforcek9149]

it's 0.004. (4 thous) on an ISX single cam

[@ntxoil8894]

What size feeler guage are you using?

[@TerraFirmaX]

It says in the video.

[@juanurrego807]

0.004 in

[@valdsonvinhotelimeira3497]

Show de powe

[@TerraFirmaX]

Huh?

[@MottyRuttner]

I like the menorah tattoo 🕎

[@TerraFirmaX]

Motty Ruttner I’ll let him know you said so

[@CanhNguyen-xw4qv]

❤❤❤❤❤❤❤❤❤❤❤❤❤❤

[@jasonwilson4345]

You are supposed to unload the bottom gear set your backlash for 10 thousands and your end result is 4 thousands between your top 3 gears after you reload the bottom gear

[@TerraFirmaX]

hmmmm. I don't remember reading that on Cummins, I could be wrong

[@earvingmoscoso9508]

Was wondering if he did that. Also depends. If your lower idler gear is a scissor gear yes, if it's a solid gear then no.

[@feedsmithy]

Aaah, maybe this is late, but he does it %100 correctly. 2x 4 thou feeler gauges. 10 thou was the old spec, but it gave to much gear train noise, so they went down to 4 thou! Great job guys!

[@TerraFirmaX]

@@feedsmithy just saw your comment. Thank you. I got nothing but grief about the lash.

[@ajalathompson]

youre damaging your torque wrench using it to turn 60 degrees

[@TerraFirmaX]

It's designed to do the 60 deg, thanks

[@chrispatrick8903]

Easy to do simple engine.

[@TerraFirmaX]

Well thanks Chris.

[@reneurvina5825]

sub español por favor

[@angelramirez7560]

I'm sorry but this is wrong the feller Guage is too big therefore ,, the loco gear is way too high

[@darrellrobinson6178]

What number wedge did you use for the cam

[@TerraFirmaX]

I don't remember, I'm sure I mentioned it in the video., but I can look it up if you really need

[@TerraFirmaX]

I guess I didn't mention it in the video. I think it's on the valve cover though

[@darrellrobinson6178]

Did you get that 4 thousands backlash is because of the aftermarket head you using because I look at the PDF on cummins thay says between 9 and 10
