If there is found excessive axial clearance at the wheel, adjust it as follows:
unscrew the hub cup;
- Remove the castellated nut securing pin;
- Rotate the wheel by hand and tighten the castellated nut to the beginning of the wheel braking;
- Turn back the nut to nearest groove enabling to secure with locking pin;
- Put the pin (wheel should rotate freely in bearings showing no clearance);
- Fill the bearing with grease;
- Screw the hub cup.
