Piston Inspection
1. NOTICE: Do not use a caustic cleaning solution or a wire brush to clean pistons or piston damage may occur.
NOTICE: Extreme care must be used when cleaning piston ring grooves on aluminum pistons or piston damage may occur.
Clean the pistons with liquid soap and water.
2. NOTE: Use the top compression ring to clean the top ring groove, and the bottom compression ring to clean the bottom ring groove. Because the
ring grooves are different designs, using the wrong compression ring to clean each ring groove will damage the piston.
Break the old compression rings in half, then use the compression rings to clean the piston ring groove areas of the piston.
