CHAPTER 5

5.6

Gently tap the hub with a rubber or wooden hammer.

The wheel should rotate smoothly, without jams and no noticeable resistance, not from

rubbing the shoes against the brake drum. Adjusting of the bearing looseness can only be

carried out when the trailer is connected to the tractor and the loading box is empty.

FIGURE 5.2.

Adjustment of axle bearings

(1) hub cover, (2) crown nut, (3) cotter pin

ADVICE

If the wheel is removed, the bearing clearance is easier to check and adjust.

5.2.4 WHEEL ASSEMBLY AND DISASSEMBLY, CHECKING NUT TIGHTNESS

Wheel disassembly

Block the trailer with parking brake.

Place blocking chocks under the wheel that will not be removed.

Ensure that the trailer is properly secured and will not move during wheel

dismantling.
