face. Turning will make the drum too thin
causing drum and brake failure which could
cause severe injury or death.
Wear a dust mask and eye protection when-
ever working on wheel brakes. Do not use
pressurized air to blow dust from brake
assemblies.
Remove cap to gain access to the castellated nut and the
cotter pin (Ref Fig. 5 on page D-6).
Remove the cotter pin and castellated nut as shown.
Do not apply the brake when removing the nut
as the shoes may not fully retract preventing
removal of the brake drum.
Remove washer.
Slide the brake drum from the axle shaft. If required, tap
the drum with a plastic faced hammer to loosen it from
the axle shaft or use drum puller (P/N 15947-G1).
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.
Pay particular attention to the location of the
inner brake drum washer inside the brake
drum, which may be on the axle shaft or attached to the rear of
the drum hub. This washer must be reinstalled when the brake
is reassembled.
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 inner brake drum
washer and slide the brake drum into place. Check to
insure the nose of drum hub is beyond the end of the
axle splines. If not, remove drum and install one addi-
tional 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 cot-
ter pin.
Install the remaining hardware and tighten the nut to 70
ft. lbs. (95 Nm) torque. Continue to tighten until a new
cotter pin can be installed through the castellated nut and
the hole in the axle. Maximum torque is 140 ft. lbs. (190
Nm).
