3B-31 Differential:
Right Side Shim Selection
1) Put a few pieces of solder (1) (O.D.: 1.2 – 1.5 mm
(0.05 – 0.06 in) x L: 6 mm (0.24 in)) on the back side
of final driven gear, as shown in the figure.
NOTE
Do not install the right side shim(-s) at this
time.
2) Install the final gear case cover and tighten its bolts
to the specified torque diagonally.
Tightening torque
Final gear case cover bolt (a): 23 N·m (2.3 kgf-
m, 16.5 lb-ft)
NOTE
• Do not install new O-ring to the gear cover.
• Do not apply thread lock to the bolts.
3) Remove the final gear case cover.
4) Measure the thickness of compressed solder with
the micrometer.
Special tool
: 09900–20205 (Micrometer (0 – 25 mm))
Shim thickness
Compressed solder thickness + 0.1 mm (0.004 in)
5) Select the proper size of shim(-s) from the table,
according as the compressed solder thickness.
List of shims (for right side)
After selecting the proper size of shim(-s), check or
adjust the backlash and tooth contact.
