Cm870 Rebuild kit

[3406E]

Currently looking at rebuild kits from Cummins, it seems like they have a ton of different part number rebuild for the kits for my Engine serial 79060142. They have given me two different part numbers. One says 152mm liner kit other says 150mm. Why is this? Does it matter?

Just looked it up on quickserve, it’s showing Both 150mm and 152mm. Would like an explantion. Thanks

2 Different liners. You dont know what u got until its apart. Unless u already overhauled it once

Also you cannot rely solely on oring color anymore, measure all your liners incase you have an oddball one and order accordingly..

Does the wrist pin bushings for the road come in the rebuild kit or have to get seperately

does not come with kit unless its a platinum kit that has all new connecting rods.
