18. Install the gasket on the pump cover.
19. Install the cover plate, solenoid 7 with the retainer and the
solenoid wiring retainer to the pump cover, ensuring that
the periphery of the cover plate is flush with the periphery
of the pump cover. Refer to figure 8.34.
Tighten the screws to specification in the order (1-5), shown
in figure 8.44.
24. Install the pump and cover assembly over the input shaft
being careful not to damage the sealing rings. Tighten the
pump cover to case bolts to specification. Refer to figure
8.45. 20. Tighten the solenoid 7 screw. Refer to figure 8.39.
Notice
Check that neither the wiring nor the connector protrudes
excessively, in order that at assembly neither the wiring
and the connector contacts or rubs on the input shaft or
the C1/C2 clutch cylinder.
21. Assemble the pump to the pump cover.
Tighten all bolts and the crescent screw finger tight,
ensuring that the pump is flush against the pump cover.
Tighten the bolts and the screw to specification in the order
(A - F), shown in figure 8.44.
22. Install the pump to transmission case gasket onto the case.
23. Fit the ‘O’ ring to the pump cover outer diameter.Figure 8.44 - Pump Bolt Tightening Sequence

AUTOMATIC TRANSMISSION 5A-117
25. Check that the transmission end float is set to the tolerance
stated in section 9.2. Refer to figure 8.46. If the unshimmed
end float clearance is greater than specification, shims
are to be placed between the No. 4 bearing and the input
shaft bearing surface. Refer to figure 8.19. If the end float
clearance is less than 0.5 mm then the transmission has
been assembled incorrectly or the parts are out of
specification.
26. Perform the following steps to check the end float :
a. Attach a dial indicator to the front of the transmission
case with the stylus resting on the end of the input
shaft.
b. Apply a force of approximately 250 newtons or 25 kg to
the input shaft.
c. Zero the dial indicator.
d. Place a small lever behind the forward clutch cylinder
and lever the cylinder forward.
e. The measurement recorded on the dial indicator is the
transmission end float or clearance between the No.4
bearing and the converter support tube.
27. On completion of this procedure, adjust the front and rear
bands to specifications detailed in section 8.4.

6. Check the following Bearing for excessive war:
lCrankshaft pilot bushing for the front of the inputshaft.
lClutch release bearing.
lInput shaft bearing.
lMain shaft pilot bearing rollers.
lMain shaft thrust Bearing and its surfaces.
lSpeed gear roller bearing on the main shaft.
lMain shaft rear bearing.
lCounter shaft front and rear bearings.

9. Take apart the three synchronizer assemblies and check :
lThe 1-2 synchronizer.
lThe 5th blocking ring.
10. Check the fit between the hub and sleeve of each
synchronizer
lExcessively tight or loose hub-to-sleeve fit.
lWear of the cone clutch surfaces of brass blocking
rings and gears.
11. Measure the clearance between the blocking ring and the
speed gear
lNew 1-2 blocking ring : 0.87-1.4mm
lNew 3-4 blocking ring : 0.88-1.5mm
Notice
Excessive wear of the blocking ring or the speed gear cone
surface will cause shift block-out gear clash.

12. Check for gear clash on the synchronizer sleeve teeth or
the clutch teeth on the speed gear.
13. Check the synchronizer sleeve and gear clutch tooth for
hop-out.
