a. Front wheel, ball‐bearing hub, is similar to a bicycle front hub as far as adjustment is concerned. Do not completely disassemble hub for adjustment as balls are not in retainers, and will fall out when cone is removed. Hub is provided with grease deflector sleeve and felt retainer. NOTE: Earlier models are not equipped with grease deflector sleeve or felt retainer washer. Front wheel should have slight play or shake on bearings, and should turn freely.

Figure 83—Disassembly for Rear Wheel Removal
(1) Remove front wheel (par. [125]).
(2) Back off cone lock nut to end of axle sleeve. Do not remove nut.
(3) Turn cone on axle sleeve to the right (clockwise) to take up wheel play, and to the left (counterclockwise) to give more wheel play. Adjust so that wheel has slight play on bearing.
(4) Tighten cone lock nut. After tightening nut, again try for slight wheel play on bearing. Sometimes tightening lock nut takes up on bearing play. If necessary, readjust for desired results when cone lock nut is tight.
(5) Install front wheel and brake assembly (par. [125]).
