Timing Chain Replacement
- Remove fan belt, crankshaft pulley mounting bolts and pulley.NOTE: Pulley can generally be removed by hand.
- Remove timing chain cover, oil slinger, and chain tensioner (tensioner is spring loaded). Mark forward side of timing chain so it can be reinstalled in its original position.
- Remove camshaft sprocket mounting bolt and washer. Remove camshaft and crankshaft sprockets together with timing chain.
- To install, fit crankshaft sprocket (smaller sprocket) onto crankshaft so index mark is facing toward front.
- Install camshaft sprocket (larger sprocket) onto camshaft and lock pin so index mark is facing front.
- Adjust both sprockets until index marks are opposite each other.
- Prior to installation of timing chain tensioner assembly, inspect for visual signs of wear. Chain tensioner may be disassembled. If any parts are found defective, complete assembly must be replaced.
- Insert chain tensioner compression spring into adjusting piston.NOTE: Compression spring must be installed into plunger so helical slot of adjusting piston and guide pin fit into each other in plunger sleeve.
- With 1/8" Allen wrench, turn adjusting piston clockwise until guide pin engages top of helical slot blocking piston for installation purposes. Slide plunger sleeve into tensioner body and bolt body to front of engine. Remove end plug and lock plate, release adjusting piston. Reinstall end plug.
- Reverse removal procedure for remaining components.
