INSPECTION OF REAR 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.

races (A540H) for the end of stator shaft. If the thrust
play is in excess of standard, select one of them.

(c) Using a dial indicator, measure the backlash of one
pinion gear while holding the side gear toward the
case.
Standard backlash: 0.05 - 0.20 mm
(0.002 - 0.0079 in.)
HINT: Do not place in a vise the surface of the center
differential case which comes in contact with the bushing.
Referring to the table below, select the thrust washer
which will ensure that the backlash is within specification.
Try to select a washer of the same size.

5. INSPECT AND ADJUST SHIFT CABLE
When shifting the shift lever from the N position to oth-
er positions, check that the lever can be shifted
smoothly and accurately to each position and that the
position indicator correctly indicates the position.
