s. Install the pump on the washer of transfer case of housing.
t . Make the O-ring is proper for the external diameter of pump.
u. Ensure the pump housing hole in main housing is clean and without dirt.
v. Ensure the plastic connector of solenoid valve 7 is installed on the correct position of main housing.
w. Install the pump and pump housing on the input shaft carefully and avoid the damage of gasket spring. Tighten the pump
housing spring. Refer to Figure 8.43 Figure 8.44.
x. Check whether the transmission end float is fixed in the clearance of part 9.2. Refer to It the end float without filling metal plate
is more than that in instruction, then the metal plate should be placed in surface of NO.4 bolt and input shaft bolt. Refer to
Figure 8.19. if the end float is less than 0.5mm or more than 0.8mm; then the transmission can not be installed correctly and
is beyond the specification partly.
Check the end floating by executing the following procedure:
Connect the disc indicator to the front end of the transmission; place the pointer on the end of input shaft.
Apply about 250N or 25kg force on the input shaft.
Zero the indicating pointer.
Install a small lever on rear of the front clutch cylinder.
The recorded measuring value is the end floating value or called as the clearance of No.4 bearing on torque converter
tube support.
After the completion of the process, adjust the front and rear brake belt according to the specification of details in part 8.4.

14. Valve

disc.
Refer to Figure 8.51.
f. Install the brake belt action regulating valve (BAR) spring, piston and fixed bolt. Refer to Figure 8-52
g. Install the force and action regulation valve (CAR)spring, piston and fixed bolt. Refer to Figure 8-53
Caution: The aluminum valve is damaged easily.

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.
