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.
