Piston: Service Precautions

CAUTION:
Do not use a caustic cleaning solution or a wire brush to clean the pistons (6108) or possible damage may occur.

NOTE:
Do Not Mix Components
If the connecting rod bearings, connecting rods, connecting rod caps, pistons or piston pins are to be reused, each one must be identified so that it can be installed in its original position. Components should not be mixed, but should be assembled with the components, and in the cylinder bore that they were removed from.
