There are two overhaul kits for the type of engine I have : CUMMINS ISX 2008 (C871) the difference is with the liners diameter: 150 mm or 152 mm.
I did provide the engine serial # but was told by the local part center that there is no way to know what my liners diameter is unless the engine is taken apart. That's kind of strange...The only possible deductive info might be that my engine came as 400 HP vs 475 which would could be equipped with larger cylinders.
I thought about buying the kit by the end of the year for the write off and have it ready...The motor does not show any immediate signs for the repair but with 1350 000 already, it is getting there...I think, some time next year, it will need to be done. Especially, that a new truck purchase is not an option now.
How do I know what my cylinder liner diameter is?

Are you dealing directly with Cummins or with an aftermarket parts house?
I would think Cummins would be able to tell you by your serial number.Rideandrepair and God prefers Diesels Thank this. -

150 mm liners have pink o-rings. 152mm liners have blue o-rings.

152mm was used from 2010-2012. Yours would be 150mm.

I am sure there must be a way to know this.

International told me I had dual oil coolers on my ISX, despite what I saw in Quick Serve.
Cummins confirmed it was only one.
In the end, if nobody knows for sure, maybe you can drop the pan next oil change and measure from the bottom?
Then again, there's a guy in this thread named "Truck engine machinist", and I bet he didn't chose that name on accident, lol.Rideandrepair and D.Tibbitt Thank this. -
I work on them, day in and day out. Also, do not use the brass shims that come with the liners. they smash. use only stainless steel shims.
Rideandrepair, TallJoe, black_dog106 and 2 others Thank this. -
What about the warranty? Buying it now may activate the one year or? parts warranty.
TallJoe Thanks this. -
Rideandrepair Thanks this.
