I just overhauled a Cummins N-14 and M-11 and the pistons are two piece articulated design (steel crown aluminum skirts). Inside the skirts it has Mahle cast inside. I called Mahle to see if I could go around Cummins they said there contract would not allow them but, the contract time was almost up and we would see after market kits for the M-11.
Cummins uses two suppliers for there pistons Mahle and a company called something like Kopin Schmidt(?) This is what the tech guy at Mahle has told me.
By the way GM uses the same two company's in there Duramax. Mahle was used in the LB7 and LLY engines and Kopin Schmidt in the LBZ. Guess which one has the cracking problem...
Do you have a part number for the mahle marine piston in .5mm over
