Precaution: Before the procedure below, the
careless pull may lead the disconnection of
the harness if the ABS vehicle speed sensor
is not removed first. Therefore, before the
following procedure, remove the ABS
vehicle speed sensor (the axle side) first and
fix it in a proper position in order to keep the
sensor
untouched
during
the
vehicle
maintaining.
Assemblage of the rear shock absorber
(refer to the illustration of the rear shock
absorber assy)
----Cover the rear spring bottom tray 15 onto
the rear shock absorber assy 13, fix it on
the rear shock absorber with the pressure
of 9.5~10kN, and then set the bottom
tray bearing pad with the pressure of
2~3kN.
----Cover the rear coil spring 14 and the valve
cap 12 onto the piston rod of the rear
shock absorber in sequence, and then set
into the rear bumper block 10 and the dust
cover 11 which have been assembled
together;
----Press the rear coil spring 14 to
280~300mm, and then fix the locating
ring 8, the rear spring upper soft pad 9,
the rear spring upper holder 7, the
bearing sleeve 6, and the rubber bearing
block II 5. Tighten the hexagon thin nut 4
to the specified torque (15N·m);
Installation position of the spring holder
Installation of the shock absorber spring
----As the illustration shows, aperture a must
aim at the bush of the connecting sleeve
2 when install the rear spring bottom tray,
otherwise the spring tray 1 would hit the
tire under extreme steering condition.
----As the illustration shows, please pay
attention to the installation position of
the rear spring upper soft pad.
Installation of the rear shock absorber
assy (refer to the illustration of the rear
shock absorber assy)
Installation position of the spring bottom
tray
----Install upward the rear shock absorber assy
from the vehicle body bottom and extend
the piston rod into the carriage through the
rear shock absorber holder;
----Inside the carriage, cover bowl washer 17,
rubber bearing block 18 and support disc
19 onto the piston rod in sequence, and
then tighten the hexagon nut 20 with
tightening torque of 20N·m. (shown as
the assy picture above)
----Lift the vehicle, and then put the
connecting sleeve of the rear shock
absorber
into
the
corresponding
installation position on the rear axle assy
and then tighten the bolt 21 and the nut
22 with the specified torque (70±7N·m)
----Fix the tire, ground the vehicle and
tighten the hexagon thin nut 20 with the
specified torque (25 N·m)
----Fix the belleville washer 3 and tighten the
hexagon thin nut 1 with the specified
torque (15 N·m)
----Fix the rear shock absorber upper cover 2,
in order to keep away from the dust and
dirt which could lead to abnormal wear on
the piston rod. (shown as the picture)
