2. Remove mounting bolt and locking tab washer (Detail "B" of FIGURE 9.4). Discard
existing locking tab washer.

Installing the Drive Wheel

NOTE: Ensure keystock is in the cutout on the drive shaft (Detail "B" of FIGURE 9.4). The
keystock MUST line up with the wheel hub cutout.
DO NOT apply more than a one-inch (in length) thin film of anti-seize compound to
the drive shaft. Applying more than one-inch (in length) can cause the anti-seize
compound to leak resulting in damage to flooring (carpet, tile, etc.).
1. Apply an anti-seize compound to drive shaft and keystock.
2. Align the keystock in the drive shaft with the cutout in the wheel hub and position the
wheel on to the drive shaft (Detail "B" of FIGURE 9.4).
Failure to properly install locking tab washer can result in wheel separation and
potential user injury or property damage. When replacing wheels ALWAYS use a
new locking tab washer. DO NOT reuse locking tab washers.
NOTE: The locking tab of the locking tab washer MUST be inserted into the cutout in the rim and
hub (Detail "B" of FIGURE 9.4).

drive shaft (Detail "B" of FIGURE 9.4).
