Hi.. I am looking for some Moline 800 piston dimensions. What is the pin size and compression height? Also what oversize do they exist in? They are 5.250 std correct?? Thanks

Standard I think is 5-5/16

the std bore is 5.312" the compression distance is 3.537" and the pin is 1.75" they were available in std .020, .030,.040,.060.paul

It would be more correct to say the piston is 5.312 bore size is .010 to .012 bigger.

actually the bore size is 5.312 as stated. the piston however will be .010-.012 smaller than the bore.Paul

Actually the std piston measures exactly 5.312 Piston in hand and a Micrometer to measure it acurratly. Many of the aftermarket pistons are even marked 5.312 on the top of the pistons. But by all means if you want to put it in a 5.312 hole go right ahead
