9.6 Axle and brake
In order to achieve optimal braking char-
acteristic and minimal wear of brake
linings we recommend the performance
of a drawing adaptation between tractor
and trailed sprayer.
Have this drawing adaptation carried out in a
specialist workshop, after an appropriate run-
ning-in time of the service brake system.
If you notice excessive wear of the brake linings
have the drawing adaptation carried out before
these empirical values are reached.
Adjust all vehicles acc. to the EC directive
71/320 EEC in order to avoid braking difficulties!
WARNING!
Repair and adjustment work on the
service brake system must only
be performed by specially trained
specialists.
Be extremely careful when perform-
ing welding, torch cutting and drill-
ing work near brake lines.
After completing work on the brake
system you should generally per-
form a brake test.
General visual inspection
WARNING
Perform a general visual check of
the brake system.
Pay attention to and check the following
criteria:
¾
Pipe, hose lines and coupling heads must
not show any external damage or corrosion.
¾
Joints, e.g. on fork heads must be properly
secured, light moving and should not be worn.
Ropes and actuating cables
¾
must be properly guided.
¾
should not show any noticeable damage.
¾
should not be knotted.
¾
Check the piston stroke on brake cylinders,
adjust if necessary.
The air vessel must
¾
not move in the clamping straps.
¾
not be damaged.
¾
not show any external corrosion damage.
Check the brake drum for dirt (workshop work)
¾
Unscrew both cover plates from the inner side
of the brake drum.
¾
Remove any dirt and crop residues that may
have entered.
¾
Check the lining thickness.
¾
Reassemble the cover plates.
CAUTION
Dirt that has entered may deposit on
the brake linings and thus considerably
impair the braking power.
Danger of accident!
If there is dirt inside the brake drum, the brake
linings should be inspected in an expert work-
shop.
Wheel and brake drum must be disassembled
for this purpose.
Check the wheel hub bearing clearance
(workshop work)
To check the wheel hub bearing clearance lift
up the axle, until the tyres are off the ground.
Release the brake.
Place a lever between tyre and ground and
check the clearance.
In case of noticeable bearing clearance
Adjust the bearing clearance
¾
Remove the dust cap or the hub cap.
¾
Remove the cotter pin from the axle nut.
¾
Tighten the wheel nut while turning the wheel,
until the rotating wheel hub is slightly braked.
¾
Turn the axle nut back to the next possible
cotter pin hole. In case of congruence up to
the next hole (max. 30°).
¾
Insert the cotter pin and bend it slightly open.
¾
Fill the dust cap slightly with grease and knock
or screw it into the wheel hub.
