REAR PLANETARY GEAR INSPECTION
MEASURE PLANETARY PINION GEAR THRUST
CLEARANCE
Using a feeler gauge, measure the planetary pinion gear
thrust clearance.
Standard clearance:
0.2-0.6 mm (0.008-0.024 in.)
Maximum clearance:
1.0 mm (0.039 in.)
If the clearance is greater than the maximum, replace the
planetary gear assembly.
