Remove brake drum washer.
Slide the brake drum and hub assembly from the axle
shaft. If required, tap the drum with a plastic faced ham-
mer to loosen it from the axle shaft or use drum puller
(P/N 15947G1). If shoes interfere with drum removal,
rotate adjuster bolt on back side of backing plate towards
the axle to retract shoes and remove brake drum.
To install the brake drum, clean the axle shaft and the
splines on the brake drum to remove dirt, grease and for-
eign matter. Apply a small amount of anti-seize com-
pound to the axle spline. Install the brake drum washer
and slide the brake drum into place. Check to ensure the
nose of drum hub is beyond the end of the axle splines. If
not, remove drum and install one additional inner brake
drum washer (total of 2) to obtain required spacing. If two
inner brake drum washers do not provide the required
spacing, the brake drum is incorrect and must be
replaced with a new drum.
Do not back off nut to install cotter
pin.
Install the remaining hardware and tighten the castellated
nut to specified torque value. Continue to tighten until a
new cotter pin can be installed through the castellated nut
and the hole in the axle. Do not torque more than the
maximum torque specified.
