TENSIONING THE V-BELT
If the V-belt is properly tensioned - its de-
flection must be 5.5 mm when one belt is
subject to the force of 25 N.
Tension the V-belt to the prescribed val-
ue after releasing the fixation screws (1,
2).
TENSIONING THE V-BELT OF THE
AC COMPRESSOR
If the V-belt is properly tensioned - its de-
flection must be 5.5 mm when the belt is
subject to the force of 50 N.
Tension the V-belt to the prescribed val-
ue after releasing the fixation screws of
the AC compressor.
ADJUSTING THE PLAY OF THE
BRAKE PEDALS
The proper play between the piston rod
of the brake pedals and the piston of the
main cylinder is 0.5 - 1.0 mm (3 - 6 mm
measured at the edge of the brake ped-
als with the pedals disconnected). Per-
form the adjustment with the pedals dis-
connected and after releasing the ad-
justment nut (1) that the piston rod is
screwed in.
BLEEDING THE BRAKE SYSTEM OF
THE TRACTOR
Do the bleeding with the pedals discon-
nected, for each wheel separately, as fol-
lows:
Note: When bleeding the hydrau-
lic brake circuits you must always
depress one pedal (1) by 7.5
+0,5
mm, measured at the piston rod
of the main brake cylinder, which
amounts to 3
+0,2
mm at the ad-
justment screw (2) and do the
bleeding with the other pedal. To
maintain the proper distance in-
sert between the pedal (1) and
adjustment screw (2) a gauge
with the corresponding thickness,
i.e. 3
+0,2
mm.
