TAPPET

Structure
• The tappet is a shimless tappet which is integrated with the shim.
• Besides the tappet, the grounding surface of the cam is phosphate-coated to smooth the surface and improve
abrasion resistance.
• To adjust the valve clearance, replace the tappet. There are 35 kinds of tappets depending on the thickness.
To distinguish the difference, check the engraved identification mark (3 digits).
