Hydraulic Valve Tappets
CLEANINGClean each tappet assembly in cleaning solvent to remove all varnish, gum and sludge deposits.
INSPECTION
Inspect for indications of scuffing on the side and base of each tappet body.
Inspect each tappet base for concave wear with a straightedge positioned across the base. If the base is concave, the corresponding lobe on the camshaft is also worn. Replace the camshaft and defective tappets.
