(2) Timing Gears
Timing Gear Backlash
1. Set a dial indicator (lever type) with its tip on the gear tooth.
2. Move the gear to measure the backlash, holding its mating gear.
3. If the backlash exceeds the allowable limit, check the oil
clearance of the shafts and the gear.
4. If the oil clearance is proper, replace the gear.

Idle Gear Side Clearance
1. Set a dial indicator with its tip on the idle gear (1).
2. Measure the side clearance by moving the idle gear (1) to the
front and rear.
3. If the measurement exceeds the allowable limit, replace the idle
gear collars.
W1064208
Oil Clearance between Idle Gear Shaft and Idle Gear Bushing
1. Measure the idle gear shaft O.D. with an outside micrometer.
2. Measure the idle gear bushings I.D. with an inside micrometer,
and calculate the oil clearance.
3. If the oil clearance exceeds the allowable limit, replace the
bushing.
