Check and Adjustment

Note for installation of flexible shaft

1.Ensure the adjustment for flexible shaft is making in

clear environment. If the dirt goes into the tie rod, it
will goes into the flexible shaft interior when tie rod
move, and cause the damage for flexible shaft core.

2.When adjusting the flexible shaft, do not hold dirt boot

by hand to avoid the damage for interior parts. Do not
tap the dirt boot with tool.

3.Do not damage the exteriors of flexible shaft and any sealing parts.

Adjustment of selective shift flexible shaft

1.Fit the ball joint assembly at the connecting end of

selective shift flexible shaft and gear shift, then push
the flexible shaft to the bottom to adjust the ball joint
and big nut, the dimension of A should meet the
requirement.

A=185±1mm

(1)Ball joint  

(2)Adjusting nut

(3)Locking nut

2.Install the rubber, push the rear end of flexible shaft to

the bottom to adjust the adjusting nut the length of B
should be 205mm. Ensure the relative angle of flexible
shaft clip and rubber connector is 90 degree.

Adjustment of selective shift flexible shaft

1.Fit the ball joint assembly at the connecting end of

selective shift flexible shaft and gear shift, then push
the flexible shaft to the bottom to adjust the boll joint
and big nut, the dimension of A should meet the
requirement.

(2)Adjusting nut

(3)Locking nut

2.Push the rear end of flexible shift to the bottom, screw

the adjusting nut to made the length of C is 214±1mm,
and ensure the angle relation ship of two ball joint and
the angle relationship of ball joints and flexible shaft
clip.

After finished the adjustment, tighten the adjusting

nut.

Installation of flexible shaft

The selective shift flexible shaft assembly adjusted

according to the above way can be assembled on the
truck.

1.Loosen the big nut of front end, let the flexible shaft go

through the bracket and the dirt boot plate, and then
tighten the big nut.

2.Connect the ball joint assembly with selective arm

together with self-locked nut. The flexible shaft dirt
boot must be fitted on the fixed plate.

3.Fit the front end of flexible shaft, then fit the rear end,

connect it with the transmission assembly, first fit the

flexible shaft clip on the bracket, then connect the flexible shaft with shift rock arm, the transmission should be
in neutral position.

When assembling, the flexible shaft core must not be twisted. When connecting the flexible shaft with gear-

box, the end section of flexible shaft should be about 100mm  line, then it can be bent, the bending radius is not
less than 200mm. 

When connecting the flexible shaft two end with

other parts, pay attention to assemble direction, it should
not be crooked.

Lubrication normally

Lubricating grease need not be used in flexible shaft

control system. If the noise is found in operating the flex-
ible shaft control system or it is difficult to operate the
control system, it is necessary to turn over the cab to
check whether the lubricating grease is sufficient in dirt
boot of shift level support ball knob and in dirt boot of
flexible shaft ball joint assembly. If necessary, add the
No.2 industrial Li base lubricating grease.
