Triple cone synchronizer (2nd)
Follow the instructions below and inspect the clearance of
outer baulk ring, synchronizer cone, inner baulk ring.
CAUTION:
Outer baulk ring, synchronizer cone and inner baulk ring
control clearances “A”, “B” and “C” as a set. Replace
them as a set if they are outside the limit value.
1. Measure clearance “A” at 2points or more on the opposite side
using a feeler gauge when pressing baulk ring toward clutch
gear taper cone. Then calculate the average.
2. Measure clearance “B” at 2 points or more on the opposite side
using a feeler gauge. Then calculate the average.
3. Measure clearance “C” at 2 points or more on the opposite side
using a feeler gauge when pressing baulk ring toward clutch
gear taper cone. Then calculate the average.Clearance B

FINAL DRIVEPFP:38411
Assembly and Disassembly (RS5F51A)ECS008CA
PRE-INSPECTION

Check the clearance between side gear and differential case as
follows.
1. Clean final drive assembly sufficiently to prevent side gear thrust
washer, differential case, side gear, and other parts from sticking
by gear oil.
2. Upright differential case so that side gear to be measured faces upward.
3. Place the drift below and a dial gauge onto side gear. Move side
gear up and down, and measure the clearance.
CAUTION:
There should be no resistance and gears should rotate
freely.
4. If not within specification, adjust the clearance by changing side
gear thrust washer thickness.
5. Turn differential case upside down, and measure the clearance
between side gear and differential case on the other side in the
same way.
DISASSEMBLY
1. Remove final gear mounting bolts, and then separate the final gear from differential case.
2. Remove differential side bearing (clutch housing side) using the
drift and pullers.
3. Remove differential side bearing (transaxle case side) using the
drift and pullers.
