Secure castellated nut (3) with spring-type cotter-pin (4)
and mount the hub cover (2). The wheel should rotate
easily, without jams and noticeable opposal, not being
caused by rubbing brake clutches against brake drum.
5.2. ADJUSTING BRAKES
Adjusting procedure should be performed in case of:
•
excessive backlash between brake lining and brake drum, caused by abrasive wear, and when braking
effect decreases,
•
wheel brakes operate dissymmetric ally and not simultaneously.
When brakes are properly adjusted, braking of all wheels of the machine happens in the same time.
Adjustment procedure consists in changing location of brake expander arm (1), Figure 10, in relation to brake
expander roll (2). For this purpose, you must loosen nut (4) and then adjust arm position at groove ending of shaft
(2) in proper direction, i.e.:
•
backward – in case the brake brakes too late
•
onward – in case the brake brakes too fast
When turning the wheel screw the castellated nut (3)
tight until the wheel stops. Unscrew this nut of 1/3 turn,
until the closest pin groove aligns with the hole in
journal.
