Use a powerful screwdriver to pry up the thick part of the hub cover and lift the cover evenly.
The hub cap is best removed from its place using a narrow, but not too sharp chisel
Bend the cotter pin and pull it out of the crown nut.
Loosen the hexagon nut SW 24; remove the pressure plate and outer wheel bearing.
The pressure plate (1) under the hub nut (2) can move when the wheel bearing play is set correctly. The screwdriver blade should not rest on the brake drum.
Remove the brake drum (see section "Removal the brake drum", chapter "Brakes").
Lift the sealing ring on the inside of the brake drum; pull out the inner wheel bearing.
Clean both bearings and check for wear.
Also check the outer rings in the brake drum. If signs of wear are found, new rings should be pressed in.
The wheel bearings are lubricated and installed. The wheel hub cap is filled approximately 1/2 full with grease.
The inner sealing ring is hammered in with a plastic hammer.
Adjust the wheel bearing play as described in the next section.
