External readjustment of brake bands
During operation, adjust the PTO
brake bands in the cases when:
- PTO slips;
- the above adjustment of the clearance
in the PTO belt brakes does not help.
During
the
assembly
by
the
manufacturer or repairs, the eccentric axle
(5) (Fig. H-12) is installed with its flat up
on the right and locked with the locking
plate (3) and the bolt (4);
The procedure of readjustment is as
follows:
If the clearances in the belt brakes are
adjusted, but the PTO does not transfer
the full torque, then there is no margin for
adjustment (significant wear of belts brake
linings).
In this case unscrew the bolts (6) by
5…7 turns; turn the eccentric shaft (5) of
the external adjustment mechanism by
180° and secure it with the locking plate
(3) the bolt (4).
- readjust the belt brake clearances
band brakes.
- if the problem persists,replace the PTO
bands.
