Output Gear Pinion Depth Adjustment
NOTE: This procedure sets pinion depth only. There
are no provisions for backlash adjustment.
1. Remove O-ring from output shaft housing (re-install
for final assembly).
2. Remove any existing shims from housing.
3. Install housing in transmission case. The pinion gear
and output gear should bottom against each other,
leaving a gap between housing and transmission
case that can be measured with a feeler gauge at (A).
4. Hold gears in bottomed position by applying light
pressure to the center of the output shaft. Measure the
gap with a feeler gauge and record.
5. The specified pinion depth is .012 - .016 inch (0.3mm-
0.4mm) from the bottomed position. Therefore, you
will need to install a shim pack with a thickness of .012
- .016 inch (0.3mm-0.4mm) plus the gap measured in
Step 4.


Example: Gap between housing and case is .020 inch
(0.50 mm) with no shims installed and gears
bottomed.


To obtain correct pinion depth, a shim pack with a
thickness totaling .032 - .036 inch (.8-.9mm) must be
installed.
