CRANKSHAFT SPROCKET CONSTRUCTION [LF, L3]

id0110001204a2

• High-strength chromium steel has been adopted for the crankshaft sprocket. Due to carburizing 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.
