Cleaning and Inspection

Using a gasket scraper, remove deposits from the piston surfaces. Clean gum or varnish from the piston skirt, piston pins and piston rings with solvent.





Clean the ring grooves with Piston Ring Groove Cleaner 303-D033 or equivalent or a broken piston ring. Make sure oil ring slots (or holes) are clean.

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