Service Notes

Fig. 19 Piston & Rod Assembly:

The pistons and liners are serviceable without removing the engine from the vehicle. Pistons and liners are available in standard size only and are matched sets.
NOTE: Do not mix the pistons or liners during assembly.

To remove the piston assemblies, remove the cylinder head and oil pan.

Assemble pistons to rods with the arrow on the piston facing toward the flywheel end of engine and oil hole on the connecting rod facing away oil filter side of engine, Fig. 19.

Liner protrusion must be checked prior to the final assembly of the piston and liners in the block. The liners must protrude slightly above the block to insure proper sealing by the head gasket and the head. All engine blocks are fitted with O-rings for sealing. Liner protrusion cannot be changed in blocks fitted with O-rings. However, the protrusion should be checked to ensure proper cylinder and head sealing.
