13.2 Removal

1. Remove the snap ring and remove the idle gear.
2. Since camshaft gear is press-fitted, remove
camshaft gear (valve-cam and injection pump
cam) only after disassembling the shaft
independently.
3. Remove the crankshaft gear as same procedure
as camshaft gear.

13.3 Inspection

Check the removed gears. If any gear is found
defective, replace it.
