I am ordering a piston replacement set for my stock a55. The base gasket comes in the following thickness in mm: .5,1,1.5 and 2.0.
I don't have a clue as to which size to order and have not yet taken off the cylinder. I would like to have all the parts on hand before committing mayhem on the engine.
Can someone please give me an idea?
Also, I think a needle bearing is what the wrist pin goes through on the rod. The size is 12 x 15 x 15. I assume 12 is the i.d., 15 is the o.d., and 15 is the length in mm. Does this make sense?
Any input will be appreciated
