25. Check that the transmission end float is set to the tolerancestated 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 transmissioncase 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: Crankshaft pilot bushing for the front of the input shaft.
Clutch release bearing.
Input shaft bearing.
Main shaft pilot bearing rollers.
Main shaft thrust Bearing and its surfaces.
Speed gear roller bearing on the main shaft.
Main shaft rear bearing.
Counter shaft front and rear bearings.
7. Check the gear tooth surfaces of all gear sets.
8. Check the reverse gear set surfaces. Check the surfaces of gear teeth for excessive wear, pitting, scoring and spalling
and replace if necessary.

9. Take apart the three synchronizer assemblies and check : The 1-2 synchronizer.
The 5th blocking ring.
10. Check the fit between the hub and sleeve of each synchronizer
Excessively tight or loose hub-to-sleeve fit.
Wear of the cone clutch surfaces of brass blocking rings and gears.
11. Measure the clearance between the blocking ring and the speed gear
New 1-2 blocking ring : 0.87-1.4mm
New 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.
