Oil Clearance between Idle Gear Shaft and Idle Gear Bushing
1. Measure the idle gear shaft 0.0. with an outside micrometer.
2. Measure the idle gear bushing 1.0. with an inside micrometer,
and calculate the oil clearance.
3. If the oil clearance exceeds the allowable limit, replace the
bushing.
If it still exceeds the allowable limit, replace the idle gear shaft.
