CAMSHAFT SPROCKET CONSTRUCTION [LF]
E5U011012420N02
• The sintered alloy, which has high rigidity, has been adopted for the camshaft sprocket and is quenched to
improve the abrasion resistance at the contact point with the timing chain.
• The intake camshaft sprocket is integrated (cannot be disassembled) with the variable valve timing actuator.

CRANKSHAFT SPROCKET CONSTRUCTION [LF]
E5U011012420N03
• High-strength chromium steel has been adopted for the crankshaft sprocket. Due to carbonizing protection,
abrasion resistance at all chain contact points is increased.
• The crankshaft sprocket consists of the timing chain sprocket and oil pump sprocket, which are integrated into
a single unit.
• The keyway on the crankshaft sprocket, used to position the crankshaft during installation, has been
eliminated.
