Adjustment of front and rear brake belt

1. Setting procedure of brake belt

The setting procedure of brake belt is shown as follows:

a. For the calculating method of front servo mechanism thrust lever refer to Figure 8.62,  dimension; standard A.

.Allow the air pressure is in 650/700kPa in the operating area of front servo mechanism  (external of B1),  (refer to

Figure 8.63).

. The forward dimension of thrust lever minus 3mm.

Dimension requirement for selection of shim:

Caution:

The small shim requires that the shim size is 1mm always; the available thickness is listed in Table 8.2.

.

Release air.

b.  Proper shim to end of thrust lever pole.

Check the shim for damage, worn or corrosion; replace it if necessary.

The shim is installed on the support surface between the transmission and pole flange, refer to Figure 8.62.

Install the shim by hand, and not the hammer or pressure.

Press the shim by hand until has the click the noise. The noise means the shim is clamped by the housing correctly.

     c.   Recheck the stroke of thrust lever 3mm

0.25mm.

2. Setting procedure of rear brake belt

The setting procedure of rear brake belt is shown as follows:

a. The setting of distance A is form the back surface of servo piston to inner surface of transmission, use the vernier caliper. Refer

to Figure 8.64.

A allows the air pressure of 650/700kPa is in the front servo mechanism operating area (external of B2),  (refer to Figure

8.63).

Deduct 3.75mm from the movement of piston and use the 2.5 mm shim to divide the rest distance.

Caution:

The small shim requires that the shim size is 1mm always; the available thickness is listed in Table 8.2.

. Release air.

b.  Select the proper shim for end of thrust lever pole.

Check the shim for damage, worn or corrosion; replace it if necessary.

The shim is installed on the support surface between the transmission and pole flange, refer to Figure 8.64.

Install the shim by hand, and not the hammer or pressure.

Press the shim by hand until has the click the noise. The noise means the shim is clamped by the housing correctly.

c.  Recheck the stroke of piston for 3.75mm

0.625mm.

Disassembly of drive shaft:

Remove the intermediate support bolt of drive shaft firstly (CC6460KY

is without intermediate support connecting bolt ), then remove the

connecting bolt between the drive shaft and rear axle , lastly, pull out

the drive shaft assembly from the transmission output spline shaft and

remove it in integral.

Installation of drive shaft:

1

. Firstly, check the drive shaft for damage, spline for corrosion

and connecting surface for deficiency of damage or sand hole by

itself.

2

Install the connecting spline bushing of drive shaft on the

transmission output spline shaft carefully; then install the drive

shaft intermediate support on the intermediate support bracket

of carriage.

3

.  Use the special drive shaft bolt, nut and spring shim to connect

the drive shaft to the vehicle axle ring flange and tighten it. The

tightening torque is 78

Front wheel alignment

1. Process the following inspection and eliminate

    all problems

a. Check the wear condition of tyre and proper inflation.

Tyre inflation pressure:   230kPa

b. Check the wheel bearing of front wheel for loose.

c. Check the front suspension for loose.

d. Check the steering drive device for loose.

e.   Process the standard elastic test; check thefrontvibration damper

for normal operation.

3. Install the 4-Wheel alignment instrument

Processed according to the detailed description of equipment

manufacturer.

4. Adjust the wheel angle

Remove the cover of spacing bolt of steering knuckle; check the internal

wheel’s steering angle A.

Internal wheel’s steering angle:   

32

Caution: The wheel should not touch the brake hose of car body

when the steering wheel is rotated to limit.

2. Adjust the height of car

A:Adjust the height of car to the standard value for theconvenience of

processing the front wheel alignmentinspection.

B: Front fixed bolt of lower suspension arm

The standard no-load height is: the center of front fixed boltof lower

suspension arm is 295

1mm away form theground.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

-------------------------------------------------------------------------------------------------------------------------------------------------------------

6. Adjust the wheel toe

Adjust the wheel toe according to the following method

a. Shake the car upwardly and downwardly to make the suspension

reach the stable status.

 b.  Push the car forwardly for 5m in flat ground when the front

 wheel is in the straight forward position.

c.   Mark the center of each rear wheel; measure the distance “B”

  between the marks of left and right tyre.

d.  Push the car forwardly to move the mark on the back of tyre to

 the position of front instrument.

Remarks: if the tyre moves too far, repeat the procedure (b).

e.  Measure the distance “A” ‘between the marks on front of tyre.

f.   Measure the toe of wheel.

 toe =B-A

 Inspection standard: 0-2mm

 If the toe does not consist with the specified value, it can be

 adjusted by the left and right draw-bar.

 Move the vehicle forwardly

g. Adjustment of toe: the standard value is 0

2mm.  The toe is

adjusted by rotating the cross draw-bar. When adjust the toe, it

should rotate the cross draw-bar on left and right side uniformly.

After the adjustment, tighten the lock nut, the tightening torque

is 55
