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
Caution:
a. Must not clean the solenoid valve pipe port by solvent.
b. Pay attention to the position of ball on upper of valve.
c. Pay attention to the position of 1-2 Gear and 3-4 Gear gear shift valve which may be exchanged.
d. Check the 4-3 Gear sequence valve and spring for position.
e. Check the 12mm ball on the lower of valve.
f. It should ensure install the correct pump housing (HPPC). Please must not mix the 1
st-Gearlow position ball spool
with the torque converter ball spool .
g. Check the rag of line pressure relief valve and pay attention to replace the iron shim.
h. The hole on the valve is used for fixation and safety and could not be extended.
i . When repair the transmission, it should ensure the solenoid 5 damp coil spring is not broken.
The installation procedure of valve is shown as follows:
a. Use the cleaning solvent (refer to 8.45, 8.46) to wash the upper and lower valve completely and dry it by air; check the valve
cavity, port and hole for damage or block.
b. Install the cushioning baffle positioning bolt and clean all loose parts completely.
c. Check all valves for smooth sliding on its position.
d. Install the proper pump housing, spring and ball. Check the valve and rolling bolt.
e. Install the 1-2 Gear gear shift valve, plug and fixed bolt. Refer to Figure 8.48. Install the 3-4 Gear gear shift valve and fixed bolt.
Refer to Figure 8.49.
Install the 2-3 Gear gear shift valve and fixed bolt. Refer to Figure 8.50. Install the 4-3 sequence valve, spring, plug and fixed
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.
h. Install the solenoid pressure-supply valve, spring and fixed disc. Refer to Figure 8.54.
i. Install the solenoid valve 6 bolt , spring and fixed bolt.

j. Position the 3rd feed ball (large nylon ) on the valve and solenoid supply valve filter, shown as Figure 8.54.
k. Check the separating disk for abrasion, repair or replace if necessary.
l. Check the washer of upper and lower valve for damage, replace it if necessary
m. Install the upper shim of lower position valve.
n. Install the reverse lock valve, spring and fixed disc; ensure the correct installation of valve; shown as Figure 8.55.
o. Install 5 nylon balls on the upper valve, shown as Figure 8.46. Install the upper valve shim; install the separating disk on the
upper valve.
p . Lift the separating disk to the upper valve; prevent the detection ball from falling ; install the upper valve on the low pressure
valve. Tighten all screws. Refer to Figure 8.56.

Figure 8.56 The tighten sequence of valve bolt from upper to lower
q. Install the solenoid valve 1, 2, 3, 4 and 6. Ensure the solenoid valve is clamped by the clip tightly and the bolt is tightened to
the specified torque.
Caution:
The wire harness ground wire port is protected by the solenoid valve fixing plate
r. Install the solenoid valve 5. Ensure the solenoid valve close to valve through the clip.
s. When install the valve with line pressure relief valve, it should install the tapering port of line pressure relief valve, then install
and fix the spring and disc.
t . Install the pin spring; ensure the screw is tightened to the specified torque. Check the damaged spring.
u. Install the manual gear shift valve .Refer to Figure 8.57.
Figure 8.57 Manual gear shift valve
v. It should ensure the position lever is in the position of manual 1st-Gear before install the valve on the transmission.
w. Adjust the valve on the transfer case and install the connection of manual-operated valve steering column and manual-operated
valve. Make the long end of connecting object is proper for the 1
st manual-operated valve. Install the protecting spring and
tighten it according to the specification. Refer to Figure 8.58.
x. Check the positioning drum and manual-operated valve .
