MAINTENANCE (CONTINUED)
Nev-R-Lube™ option is the latest innovation from Dexter. Nev-R-Lube™ bearings are comprised
of opposed tapered roller bearing cones sealed inside of a precision ground, one piece double
cup arrangement. These bearings are designed with a small amount of axial end play. This end
play is essential to the longevity of the bearings service life. They are lubricated, assembled and
sealed at the factory. No further lubrication is ever needed.
Before attempting any disassembly of your Dexter axle, make sure you read and follow the
instructions for the appropriate axle type.
HUB REMOVAL – STANDARD BEARINGS
.
Whenever the hub equipment on your axle must be removed for inspection or maintenance the
following procedure should be utilized.
1. Elevate and support the trailer unit per manufacturers’ instructions.
2. Remove the wheel.
3. Remove the grease capo by carefully prying progressively around the flange of the cap. If the
hub is an oil lube type, then the cap can be removed by unscrewing it counterclockwise while
holding the hub stationary.
4. Remove the cotter pin from the spindle nut.
For E-Z Lube® axles produced after February of 2002, a new type of retainer is used. Gently pry
off retainer from the nut and set aside.
5. Unscrew the spindle nut (counterclockwise) and remove the spindle washer.
6. Remove the hub from the spindle, being careful not to allow the outer bearing cone to fall out.
The inner bearing cone will be retained by the seal.
7. For 7,200 lb. (3,265 Kg) and 8,000 lb. (3,628 Kg) axles, a hub puller may be necessary to assist
in drum removal.
BRAKE DRUM INSPECTION
There are two areas of the brake drum that are subject to wear and require periodic inspection.
These two areas are the drum surface where the brake shoes make contact during stopping and the
armature surface where the magnet contacts (only in electric brakes)
The drum surface should be inspected for excessive wear or heavy scoring. If worn more than .020”
(.05 cm) oversized, or the drum has worn out of round by more that .015” (.038 cm), then the drum
surface should be re-machined. If scoring or other wear is greater than .090” (.228) on the diameter,
the drum must be replaced.
CAUTION
You must follow the maintenance procedures to prevent
damage to important structural components. Damage to
certain structural components such as wheel bearings can
cause the wheel end to come off of the axle. Loss of a
wheel end while the trailer is moving can cause you to lose
control and lead to an accident, which can result in
serious injury or death.
