INSPECTION OF OVERDRIVE PLANETARY
GEAR
MEASURE PLANETARY PINION GEAR THRUST
CLEARANCE
Using a feeler gauge, measure the planetary pinion gear thrust
clearance.
Standard clearance: 0.16 ± 0.56 mm
(0.0063 ± 0.0220 in.)
Maximum clearance: 0.61 mm
(0.0240 in.)
If the clearance is greater than the maximum, replace the
planetary gear assembly.
2. INSTALL OUTER RACES INTO COUNTER DRIVE GEAR
Using SST, press in the two outer races to both sides o1
the gear.
SST 09350±32014 (09351±32120, 09351±32150)
HINT: Press in the two outer races until they touch the snap
ring. Tap the races in straight, so that they do not tilt
ASSEMBLY OF COUNTER DRIVE GEAR

4. INSTALL REAR BEARING
Using SST, press in the bearing onto the shaft.
SST 09350±32014 (09351±32120)
HINT: Press in the bearing until the side surface of the
inner race touches the planetary carrier.
5. INSTALL COUNTER DRIVE GEAR AND FRONT
BEARING
