WHEEL MOTOR SHAFT AND BEARING ASSEMBLY PROCEDURE

1) Clean ALL assembly parts w/ lacquer thinner.
2) Dip clampnut and clamping bolt separately in lacquer thinner.
(Steps 3 thru 10 must be conducted to completion ONE assembly at a time.)
3) Press bearing cups into bearing housing. Make sure they are pressed completely against bearing shoulders.
4) Coat inner race of large cone with #609 (green) Loctite and press cone onto the shaft. Make sure the cone is completely against the shoulder of the shaft.
5) Insert shaft and large cone into bearing housing.
6) Coat inner race of small cone with #609 (green) Loctite and press small cone onto shaft.
7) Apply #272 (red) Loctite to the clampnut threads of the shaft. Apply #242 (blue) Loctite to the threads of the clamping bolt and install in the clampnut.
8) Spin clampnut onto shaft with the "B" face towards bearings. After the nut threads are fully engaged, but prior to the nut contacting the bearings,
tighten the clamping bolt until there is drag on the clamping nut (see note Fig. 1). Tighten the nut until a 20 to 30 inch pound rolling torque is achieved.
9) Tighten clamping bolt on clampnut to 70 inch pounds and recheck rolling torque. Apply inspectors lacquer to head of the bolt.
10) Allow a minimum of 24 hrs. to dry.

Note:
The slit in the clampnut
allows for loose
assembly on the shaft.
Once in position, the
clampnut clamping bolt
MUST be tightened to
a slight drag in order to
correctly engage the
threads on the shaft to
achieve the clamp
force required.

1) Rotate shaft in both
directions to assure that the
shaft turns smoothly.
2) Torque motor to 190 ft./lbs.
3) Rotate shaft again in both
directions to assure that the
shaft turns smoothly.
NOTE: Spool should be
oriented as shown for two
speed motors with model
codes 62, 63, 68, & 69.
NOTE: Slight design
variations may exist in
motors manufactured
