TAPPET CONSTRUCTION [LF]
E5U011012431N01
• The tappet is a shimless tappet which is integrated with the shim.
• The tappet surface is phosphate-coated to smooth the attaching surface to the cam and improve abrasion
resistance.
• The valve clearance can be adjusted by replacing the tappet. There are 35 kinds of tappets depending on the
thickness. The tappet kind can be determined by the engraved identification mark (3 digits).

VARIABLE VALVE TIMING MECHANISM OUTLINE [LF]
E5U011012111N04
• A variable timing mechanism, which realizes optimum valve timing according to engine operation conditions by
continuously modifying the phases of the intake camshaft and crankshaft, has been adopted.
