9. Fully seat the mainshaft by tapping its end with a plastic hammer.

12. Turn the mainshaft holder bolt (B) clockwise; stop turning when the dial gauge

has reached its maximum movement. The reading on the dial gauge is the
amount of mainshaft thrust clearance.

13. If the reading is with in the standard, the clearance is correct. If the reading is

not within the standard, select the appropriate shim needed from the table, and
recheck the thrust clearance.

Standard: 0.11-0.18 mm (0.004-0.007 in.)

(Example)

NOTE:

Do not turn the mainshaft holder bolt more than 60
degrees after the needle of the dial gauge stops
moving. Applying more pressure with the mainshaft
holder bolt could damage the transmission.

Measure reading: 1.93 mm (0.0759 in.)

Subtract the total clearance measurement from the middle of the clearance
standard 0.14 mm (0.0055 in.)

1.93 - 0.14 = 1.79 mm (0.0705 in.)

Select the shim closest to the amount calculated, for example the 1.78 mm
(0.0701 in.) shim.

14. With oil guide plate M and the appropriate size shim installed in the

transmission housing, check the thrust clearance again to verify the clearance is
within the standard.
