-
Remove the 2 retaining bolts that secure the wheel motor to the castor fork (Figure 1).
-
Mount 3 weight plates to the right side of the castor fork with 2 hex-head bolts (1/2 x 6 inch) and 2 locknuts from the kit (Figure 1).
Note: Torque the locknuts to 65 to 85 ft-lb (88 to 115 N⋅m).
-
Position the weight onto the wheel rim of the removed tire to determine the location of the valve stems and the weight mounting fasteners.
Note: Mark the 2 holes on the wheel where the weight mounting fasteners will go.
-
Install the tire with 2 lug nuts previously removed in the other 2 (unmarked) holes.
-
Thread the 2 weight adapters from the kit onto the 2 remaining wheel studs (marked holes).
