Adjustment
Clearance between parking brake
drum and friction disc is 0.65mm,
and the upper clearance is as same
as the lower clearance. Because of
friction disc wearing, this clearance
must be adjusted in time. The steps
of adjusting are shown as follows:
1. Jack up the rear axle to make one
wheel off ground.
2. Put the parking brake handle to
the lowest position, and shift the gear
to neutral position.
3. Turn the small hole on the brake
drum to the lowest side, put a screw
鄄
driver into the hole and toggle the
gear-type adjusting bolt till the brake
drum can be stopped completely,
and then return the adjusting bolt by
2-6 teeth.
If adjusting above is executed cor
鄄
rectly, when the parking brake is
tensed, the vehicle can be stopped
on a 20% ramp.
Using and maintenance
1. Check and adjust clearance be
鄄
tween the brake and the brake shoe
slice regularly.
2. When doing class -two mainte
鄄
nance, disassemble brake to check
wearing condition of brake lining . If
thickness of gasket has been worn
down by 2mm below ,
Disassemble the gasket and re
鄄
assemble it. Gasket gluing intensity:
when boosting transversely , boost
鄄
ing by 2.94mpa under normal atmo
鄄
spheric temperature is not allowed to
dropped. Glued gasket should be
rubbing processed. Size (after rub

Wheel and spare wheel riser
Wheel
Brief description
Every truck has seven wheels in all,
one of which is spare wheel.
Using and maintenance
In order to use for a longer time,
please charge tire according to
specified pressure valve. Never drive
when pressure is insufficient. It is
normal that pressure increases dur
鄄
ing travel, and do not try to reduce it
by deflating. Check the tire pressure
when tire is not hot. If the two central
patterns on tire tread touch against
ground under fully loaded, the pres
鄄
sure is normal.
Clean the rust and other dirty on rim
before installed. It should be talked
on the surface between inner tube
and outer tire. Wheel nuts should be
tightened with two steps. Tighten all
of them firstly before tightening them
with specified torque according to
diagonal sequence.
Check wheel nuts regularly, and
retighten them with torque if loosen
鄄
ing is detected.
Transposition of tires should be done
in class-three maintenance to ensure
even wearing. Tires are usually
changed with each other acrossed.
