Engine/Transmission (1994 - 1998) Marine Pistons?

[DieselNasty]

I want to in put a set of these pistons, when I call Cummins to order them I need a part #, does anyone have this for me?



Oh and anyone that is running these how do yall like them?



Also how bout the marine head gasket with Orings and studs, or are there any other recomendations?



Thanks

Well I dont have the piston PN#,s but the CPL # for a 370 hp marine 12 valve is # 2208 which should be enouph for them to go by ,but don,t hold your breath. #@$%!

THE P/N FOR THE 370HP 12V MARINE PISTON KIT IS 3800756 ( std size ). The head gasket is the same as our truck engines - p/n 3283335 ( std size ). Shadrach

Thanks for the numbers, anyone now the numbers for . 010 over pistons? I always though that a marine gasket was thicker then stock 12v gaskets?

Cummins p/n 3800760 is . 50mm o/s. P/n 3800761 is 1. 00mm o/s. There is also a salvage sleeve to bring back a cylinder bore to stock. it is p/n 3904166. Shadrach

Ok Im guessing . 5mm is the smallest oversize?

 

[Vaughn MacKenzie]

I think so. 0. 5mm = . 020 inches.

There are 2 over sizes . 5mm (. 020) and 1. 0mm (. 040) and the salvage sleeve that restores the bore to standard size.
