Disc Brake Servicing
12. Hub Lubrication (Oil)
IMPORTANT:
DO NOT mix oil with grease. If the bearing
assembly has been lubricated with grease,
DO NOT add oil.
Failure to correctly lubricate bearings could
damage bearings which, if not avoided,
could result in death or serious injury.
1. Remove plug and fill the hub to the FULL mark with specified
lubricant (oil), through the hole in the hub cap
(Figure 35).
2. Allow the oil to flow through the bearings and level off.
3. Insert the plug into the hole in the hub cap
(Figure 35).
IMPORTANT:
Axles equipped with a centralized tire inflation
system MUST use a vented hub cap.
4. Re-install wheel on hub using support device such as a
wheel dolly jack
.
Failure to support weight during installation
or removal of brake drum could create a
crush hazard which, if not avoided, could
result in minor to moderate injury.
Failure to uncage spring brakes in accordance
with manufacturer’s instructions after
servicing is complete will prohibit proper
brake function which could result in
uneven brake system component wear.
13. Hub Cap Installation
1. Install the hub cap assembly, making sure the hub cap
gasket is in place
(Figure 36)
.
IMPORTANT:
When installing hub cap, make sure the
hub cap gasket is not bent or damaged.
IMPORTANT:
DO NOT over torque. This can crush the
hub cap gasket.
Failure to avoid damaging the hub cap gasket
could allow lubricant to lead which, if not
avoided, could result in bearing failure.
2. Install the six (6) bolts to secure the hub cap assembly
(Figure 36)
. Tighten bolts to 12-16 ft.-lbs. (16-21 N•m).
