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.
ASSEMBLY OF COUNTER DRIVE GEAR
1. INSTALL SNAP RING INTO COUNTER GEAR
Install the snap ring with a screwdriver.
2. INSTALL OUTER RACES INTO COUNTER DRIVE
GEAR
Using SST, press in the two outer races to both sides
of 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.

6. INSTALL INTERMEDIATE SHAFT BEARING
Using SST, press in the bearing until it slightly touches
the front bearing of the counter drive gear.
SST 09350-32014 (09351-32120)
HINT: The counter drive gear can be turned lightly.
7. PLACE NEW LOCKING WASHER
8. INSTALL ADJUSTING NUT AND ADJUST PRELOAD
OF COUNTER DRIVE GEAR
(a) Hold the overdrive planetary gear in a vise with
soft jaws.
(b) Using SST, tighten the adjusting nut until the fol-
lowing gear starting load is reached on the ten-
sion gauge.
SST 09350-32014 (09351-32080)
Preload (at starting): 940-1,560 g
(2.1-3.4 lb, 9.2-15.3 N)
HINT: Turn the counter drive gear right and left several
times before measuring the preload.
(c) Lock the adjusting nut with one tab on locking
washer. Bend the locking washer tab until it is
even with the adjusting nut groove.
9. INSTALL NO. 3 OVERDRIVE PLANETARY THRUST
WASHER
10. INSTALL PINION SHAFT PLUGS
Install the four plugs into the pinion shaft.
