HUB AND BRAKE DRUM (cont)
INSTALLATION OF HUB AND BRAKE DRUM ASSEMBLY ON AXLE (cont)
While turning hub slowly, tighten inner bearing adjusting nut, using locknut wrench, until hub binds on spindle.
Back off nut about one-eighth turn. Check adjustment by attempting to rock hub on spindle. If bearings are
properly adjusted, movement of brake drum in relation to top edge of backing plate will scarcely be visible and
brake drum will turn freely. If movement is excessive, repeat procedure.
Install nut locking key washer (6) on spindle.
With a minimum of movement, adjust bearing adjusting nut (5) so that flats of nut will mate with locking
lugs on key washer (6).
Install outer bearing adjusting nut (5), using
wheel bearing locknut wrench, drawing it up
tightly against nut locking key washer (6). Take
care not to disturb bearing adjustment.
Bend one or two locking lugs of key washer (.6)
over outer and inner adjusting nuts (5). Recheck
adjustment (step 7 above).
Position hub cap (3) and gasket (4) and secure
with three screws (1) and washers (2).
