Timing Chain & Sprockets: Installation
- Install Woodruff keys, timing sprocket, and oil pump pinion gear (grooved side toward front cover). Turn crankshaft so that Woodruff key is facing upward (No. 1 and No. 4 pistons on TDC).
- Timing chain has 2 marked link plates that are used for sprocket alignment purposes. The side of the chain with more links between the marked plates must be installed on the chain guide side of the engine.
- Install chain on crankshaft sprocket, aligning one of the marked link plates with mark on crankshaft sprocket. Position chain around camshaft sprocket, so marked link plate aligns with triangular mark on camshaft sprocket.
- Install camshaft sprocket on camshaft. Ensure timing marks on sprockets are still aligned with marked plates. See Fig 1 . Install remaining components in reverse order of removal.
