Repairing the Pinion (Fig. 15)
NOTE: Use a hydraulic press if you purchase the pin-
ion parts individually. Otherwise, use Repair Kit No.
223189, which includes the shaft and bearings pre–as-
sembled and lubricated.
If using Repair Kit 223189, follow Steps 1 to 7, below.
1. Remove the small ring (2j) from the hub (2h) and
the large ring (2k) from the bearing recess of the
housing (2a).
2. Push on front of the shaft (2f) to force the bearing
and hub assembly out of the housing (2a).
3. Press the small bearing (2n) and roller clutch (2m)
out of the pinion housing (2a). Remove the new
bearing and roller clutch from the shaft of the kit
and press it into the housing to the dimension
shown. Directional arrow of roller clutch (2m) must
face bearing (2n). See Detail A.
4. Inspect o-ring (2p) and replace if necessary.
5. Install the shaft assembly, pushing it to the shoul-
der of the housing (2a).
6. Install rings (2k and 2j). Ring (2k) must be installed
with bevel facing back of pinion housing.
7. Go to Reassembly, page 34, Step 7, or continue
on page 28.
If you purchased parts separately, follow steps 1 to
9, below. Disassemble only as far as needed for the
parts being replaced.
NOTE: The old bearing (2g) will be damaged as it is
removed. Have one on hand if you need to remove it
for any reason. Always replace bearing 2g if installing
a new hub 2h.
1. To replace small bearing (2n) or roller clutch (2m),
press the old one out of the pinion housing (2a).

Hub (2h) onto the shaft (2f) all the way to the
large bearing (2g).
7. Install the shaft assembly, pushing it to the shoul-
der of the housing (2a).
8. Install the rings (2k and 2j).
