Reassembly
1. Tap the new bearings on the shaft with a pipe.
2. Install new oil seals after replacing the bearing
races.
3. Replace the shaft in the housing. Install a new
seal in the retainer cap. Use the original shims
and replace the O-ring if needed.
4. Install the retainer cap assembly over the
shaft, then install the bolts.
5. Torque the bolts in a criss-cross pattern in
equal steps to 80 in-lb (9.04 N•m).
6. Lock the assembly in a vise and set up a dial
indicator to read end-play. To measure the
end-play, rotate the shaft while pushing in one
direction and set the dial indicator to ‘0’. Now
rotate the shaft and pull in the opposite
direction while reading the dial indicator.
End-play should be 0.001 to 0.005 in. (0.025
to 0.127 mm). If end-play is incorrect, use
different shims to obtain correct end-play.
7. After correct end-play is obtained, add oil for
the bearings.
8. Lock the assembly in a vise with the vent
facing up. Pour the oil (P/N 203-278) through
the top plug until it runs out of the side hole.
The assembly holds 2.5 oz (74 ml). Check the
condition of the O-ring used on the plugs and
replace if necessary. Install the top and side
plugs. Clean up any spillage.
9. Place the assembly on the workbench with the
vent up. Rotate the shaft by hand. The shaft
should be free enough to rotate without having
to hold the housing.
