Information:

Two Piece Piston Group.
When handling the piston assembly, be aware that the piston pin plug which fits on the end of the piston pin, is only used to prevent the piston pin from scuffing the cylinders. It does not retain the pin in the assembly, once the piston assembly is removed from the cylinder, the pin is free to fall out of the assembly at any time.
(1) Crater. The piston is a symmetrical piston with an "on center" crater. Thoroughly lubricate piston group 360 degrees in zone (A) with clean engine oil prior to inserting into the block group.(2) Top piston ring.
