Mainshaft Inspection
1. Inspect the gear surface and bearing surface for
wear and damage, then measure the mainshaft at
points A, B, C, D, and E. lf any part of the mainshaft
is less than the service limit, reDlace it with a new
o ne.

Countershaft Disassembly
1.Securely clamp the countershaft assembly in a
bench vlse with wood blocks.
Remove the special bolt (left-hand threads).
Support the ball bearing (A) on steel blocks, then
use a press (B) and an attachment (C)to press the
countershaft out of the ball bearing.
4. Remove the 35 mm shim and distance collar.

Cou ntershaft lnspection
1. Inspect the gear surface and bearing surface for
wear and damage, then measure the countershaft
at points A, B, and C. lf any part of the countershaft
is less than the service limit, replace it with a new
one.

lnspect the runout by supporting both ends of lhe
countershaft. Rotate the countershaft two complete
revolutions when measuring the runout. lf the
runout exceeds the service Iimit, replace the
countershaft with a new one.
Standard: 0.02 mm (0.001 in.) max.

13. Attach the special tool to the mainshaft as follows:
. Back-out the mainshaft holder bolt {A) andloosen
the two hex bolts (B).
. Fit the holder over the mainshaft so its lip is
towards the transmission.. Align the mainshaft holder's lip around the
groove at the inside of the mainshaft splines,
then tighten the hex bolts.

Seat the mainshaft fully by tapping its end with a
plastic hammer.
Thread the mainshaft holder bolt in until it just
contacts the wide surface of the mainshaft base.
16. Zero a dial gauge {A) on the end ofthe mainshaft.
Turn the mainshaft holder bolt (B) clockwise; stop
turning when the dial gauge (A) has reached its
maximum movement. The reading on the dial
gauge is the amount of mainshaft end play
NOTE: Do not turn the mainshaft holder bolt more
than 60 degrees after the needle of the dial gauge
stops moving, this may damage the transmission.
lf the reading is within the standard, the clearance
is correct. lf the reading is not within the standard,
recheck the shim thickness.
Standard: 0.11 -0.17 mm (0.004 0.007 in.)
