Backlash between Internal Gear and Planetary Gear
1. Set a dial indicator (lever type) on the tooth of the planetary
gear.
2. Hold the planetary gear support and move only the planetary
gear to measure the backlash.
3. If the measurement exceeds the allowable limit, check the
planetary gear and planetary shaft.

Thrust Collar Thickness
1. Measure the thickness of the thrust collar.
2. If the measurement is less than the allowable limit, replace it.

Clearance between Planetary Gear and Planetary Gear Shaft
1. Measure the planetary gear shaft O.D. (rubbing surface).
2. Measure planetary gear I.D. (rubbing surface).
3. Measure the O.D. of the two needles installed diagonally in the
needle bearing.
4. Calculate the clearance.
5. (Clearance = Planetary gear I.D. - {(2 x Needle O.D.) +
Planetary gear shaft O.D.}).
6. If the clearance exceeds the allowable limit, replace them.
