6.3 ADJUSTMENT OF THE CLEARANCE OF THE AXLE
BEARINGS
• Remove the hub cover (1).
• Remove the cotter pin (2) securing
the castellated nut (3).
• Tighten the castellated nut to remove
slack.
The wheel should rotate with
slight resist.
• Unscrew the nut (3) (not less than 1/3
of a turn) to cover the nearest groove
of the nut with a hole in the journal of
the axle (the pin's hole is marked with
a black arrow in the drawing). The
wheel should rotate with slight resist.
Do not over tighten the nut. Too
much pressure is not recom-
mended due to deterioration of
bearing operating conditions.
• Secure castellated nut with cotter pin
and mount hub cap (1).
• Gently tap the hub with a rubber or
wooden hammer.
J.3.4.622.04.1.EN
