The "V" on idler gear (3) should be in alignment with the "V" mark on the crankshaft gear. The "K" marks on the camshaft gear can be seen at outer edges of the idler gear.2. Remove bolts (1). Plate (2) and idler gear (3) from the shaft. 3. Remove bearing (4) from the idler gear. 4. Use tooling (A) and remove camshaft gear (5) from the camshaft.
Do not turn the crankshaft with camshaft gear removed. Damage can be caused to pistons and valves or both.
5. Remove bolts (6) and retainer (7) from the timing gear plate. 6. Remove bolts (8), timing gear plate (9) and the gasket from the cylinder block.Install Timing Gears And Plate

The inside diameter of the bearing after assembly must 63.602 0.038 mm (2.504 0.024 in.). 8. Put idler gear (5) in position on the shaft.9. Make sure the "V" mark on idler gear (5) is in alignment with the "V" mark on the crankshaft gear and the "K" marks on the camshaft gear can be seen at the outer edges of the idler gear. 10. Install plate (6) and the bolts that hold idler gear (5) in place on the shaft.END BY:a) install timing gear coverb) install automatic timing advance
