ISX cracked counterbores

Not bad.

 

Quite reasonable really if you consider the alternative.

 

2050 Tq motor?

I think the high TQ motors have a clutch issue with the friction plate springs being too weak... Giving gear rattle.

Would this describe what you're hearing?

 

Yup 565/2050 and that makes perfect sense it seems like the clutch is doing something wierd. Had it adjusted around 15,000 miles because it had moved from about middle throw engagement to the top and its up at the top again now at 45,000 miles. Ive always thought it was a clutch issue but it dosent seem to slip but it does seem to change RPM spots so I had kinda chalked it up to a programing issue with the injection events.

 

Good evening. If you don't mind me asking, but where are you located? Preparing to do inframe on my ISX15 and I am freaking out with the cracked blocks I keep hearing.

 

Funny you say that. Got a close friend that is going through that with his 2012 KW. Any experiences with a 2015 model?

 

I really appreciate you sharing this information. I live in Houston, TX and the machinist I have used in the past is very cautious and unwilling to cut a cracked block. Claims that because it is weak point, it might come back and he will not warranty. Can't really blame him, but I would like some good news for a change with these Cummins. Gonna toss this info to him and see if I can convince him. If not, I will definitely reach out. Thank you for your response.
