Remove the brake drum (see subsection 7.2.1.).
The hub has two single-row roller bearings. During operation, it is necessary to adjust the clearances and replace the grease in the bearings.
If, when rocking a suspended wheel, you feel play that cannot be eliminated by adjustment, or noise appears while driving, there is a possibility that the hub bearings have failed.
One of the hub bearings may be faulty. The bearings should rotate freely, without jamming. The rollers and bearing rings should not have any pits, chipping or signs of wear. Replace the defective bearing.
1. Through the hole in the drum (having removed the plug) knock the protective ring off the hub.
2. Using a screwdriver, pry the seal out of the hub.
3. Remove the rear bearing from the hub.
4. Using a punch or drift, press the outer rings of both bearings out of the hub.
5. Rinse thoroughly with kerosene or white spirit and dry the inside of the hub.
6. Install the outer race of the rear bearing with the smaller inner diameter inside the hub and press the race until it stops in the hub using a suitable mandrel.
