9.3.7 Tandem axle
Compressed air system and hydraulic brake
The brake activation has been adjusted in
the factory.
The brake must be readjusted:
• if the effect of braking diminishes.
(because of wear on the brake shoes,
for example).
• if the activation path of the brake
cylinder "X" is greater than 50 mm.
Adjust the braking activation:
Each time before you readjust the brake
linkage (2a, 2b), the thickness of the lining
on the brake shoes must be checked. The
thickness of the lining must still be at least
2 mm.
• Disconnect the brake linkage (2b) from the brake
lever (4)
• Loosen the counter nuts (1) on the brake linkage (2a).
• Turn the brake linkage (2a) until the brake lever path
a1 is about 30 mm on activation.
The compensation lever (11) must be flush
both in the oblong hole (I), and in the
upper part (II) of the support (12) for all
settings.
• Disconnect the brake linkage (2a) from the brake
lever (5).
• Then mount the brake linkage (2b) on the brake lever
(4) again (note the length of the brake lever (HL)).
• Loosen the counter nuts (3) on the brake linkage (2b)
• Turn the brake linkage (2b) until the brake lever path
a2 is about 30 mm on activation.
The compensation lever (11) must be flush
both in the oblong hole (I), and in the
upper part (II) of the support (12) for all
settings.
• Then mount the brake linkage (2a) on the brake lever
(5) again (note the length of the brake lever (HL)).
• Activate the brake. When you do this, the cylinder
stroke X must be between 25 mm and 50 mm.
If the cylinder stroke X is too great,
readjust the brake linkage (2a, 2b)
(increase the length of the brake linkage).
After the brake linkage (2a, 2b) has
been readjusted, check whether the
wheels turn freely when the brake is
released. If they do not, the brake
linkage (2a, 2b) must be readjusted
(shorten the brake linkage)
The threading overhang (6) of the brake
linkage (2a, 2b) on the clevises must be
min. = 0 mm.
If the minimum threading length (6)
(min. = 0 mm) cannot be reached, the
brake lever (4, 5) should be moved on
the brake shafts against the operating
direction (7).
• Tighten counter nuts (1, 3) on the brake linkages
(2a, 2b).
Make certain that all safety equipment is
mounted.
• The adjustment jobs listed below must only be performed while the machine is turned off.
Switch off the engine, remove the ignition key and disconnect the 12 V supply voltage.
• Secure the round baler and tractor against rolling.
