Adjusting the power takeoff
shaft
External readjustment of PTO brake
bands
During operation adjust PTO brake
bands, if:
1 . PTO slips.
2 . When being repositioned, the PTO
control lever rests against the front
or rear part of the control panel slot.
3 . When passing through the neutral
position, there is neither click nor
higher resistance.
4 . The force to be applied to the control
lever (1) exceeds 150 N (15 kgf).
Procedure of the external readjust -
ment:
1 . Put the arm (9) to the neutral position
(the holes in the arm (9) and in the
rear axle housing coincide), fix this
position by means of a rod 8 mm or
a bolt M 10x60.
2 . Remove the PTO enclosure together
with the plate.
3 . Turn out the bolt (17), take the lock
bar (16) off the butt of the supple-
mentary shaft (15) and turn the axle
with the brake band clockwise using
a wrench 8=13 mm to take out the
gap between the brake band and the
drum (this will be clear by the im-
possible turning of the PTO shank
by hand), then turn the axle counter-
clockwise by 10-15.
4 . Mount the bar (16) and lock it with the
bolt (17).
5 . Remove the rod or bolt from the lever
(9).
If the adjustment is made properly, the
lever (1) in position “ON” will be at the
distance of at least 35 mm from the con-
trol panel slot edge and will be neatly
pass through neutral position (dead cen-
tre).
IMPORTANT! After several external read-
justments, the eccentric shaft (15) can
take the leftmost position (the flat is o n
the left vertically), which indicates the
missing reserve of external adjustment. In
this case, set the eccentric shaft to initial
position by rotating it counter-clockwise
(the flat is on the right vertically). Then
make adjustments as described accord-
ing to the section “Adjusting the control
when repairing the PTO”.
