Clearance between Planetary Gear and Planetary Gear Shaft
1. Measure the planetary gear shaft O.D. (rubbing surface).
2. Measure the 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 × Needle O.D.) + Planetary
gear shaft O.D.}).
6. If the clearance exceeds the allowable limit, replace them.
