MAINTENANCE
Brake Pads
Inspect brake pads (
A
) for wear. If pad thickness
is under 1.6 mm (1/16 in.), replace the parts. See
Figure 33.
Figure 33
Ball Joint - Anti-rotation Arm
Inspect ball joint on Strut rod. Make sure that it is
not seized or too loose. Figure 34.
CAUTION: A damaged ball joint can make the
System difficult to adjust and result in damages if
not replaced.
Figure 34
Track Drive Sprockets
Inspect the Sprockets that drive the Track. If the
Track is set to the required tension (19 mm
deflection for an applied force of 6.8 kg) and that
the sprockets miss or skip over some of the
driving lugs, the sprockets must be replaced.
Nylon Protector and Guides - chains
Replace nylon protector and guides when they
are worn out and let the chain pass too near the
frame. See Figure 35.
Figure 35
Chain Drive Sprockets
Inspect the chain drive sprockets (
A
) for wear. If
the chain is set to the required tension (3-6 mm
[1/8-1/4 in.] deflection) and the chain misses or
skips over some of the driving teeth, the
sprockets must be replaced. Figure 36.
CAUTION: If a chain is replaced, the sprockets
should be replaced at the same time. Assembly of
new and used parts can speed up wear of the new
components installed on the drive system.
