CAUTION:

• Be careful with orientation of 5th main gear.
• Never reuse 5th main gear.

14. Install 5th-6th mainshaft spacer.

15. Press in 6th main gear using the drifts.

CAUTION:

Never reuse 6th main gear.

16. Select 6th main gear adjusting shim and then install it onto mainshaft.

• Calculate thickness “S” of 6th main gear adjusting shim follow-

ing the procedure below so that end play dimension between
6th main gear and mainshaft rear bearing becomes the dimen-
sion shown below.

CAUTION:

Only one adjusting shim can be selected.

a.

Measure dimension “S

1

” and “S

2

” using a height gauge (A) and

pick tester (B).

b.

Install selected 6th main gear adjusting shim to mainshaft.

of mainshaft rear bearing satisfies the standard value. 

• If measurement is outside the standard range, reselect main-

shaft C-rings.

19. Install C-ring holder and then install snap ring.

CAUTION:

Never reuse snap ring.

20. Check end play of 1st and 2nd main gears.

Check items below. If necessary, replace them with new ones.
• Damage, peeling, dent, uneven wear, bending, etc. of shaft
• Excessive wear, damage, peeling, etc. of gears
• Excessive wear, damage, peeling, etc. of cam side of clutch gears

SYNCHRONIZER

Synchronizer Hub and Coupling Sleeve

Check items below. If necessary, replace them with new ones.
• Damage and unusual wear on contact surfaces of coupling sleeve,

synchronizer hub and shifting insert.

• Coupling sleeve and synchronizer hub must move smoothly.

Baulk Ring and Spread Spring

Check items below. If necessary, replace them with new ones.
• If any crack, damage, or excessive wear is found on cam face of

baulk ring or working face of insert, replace it.

Baulk Ring Clearance for Double Cone Synchronizer

Check the clearance between outer baulk ring, synchronizer cone,
and inner baulk ring as follows.

CAUTION:

The clearances “A” and “B” are controlled with outer baulk
ring, synchronizer cone, and inner baulk ring as a set. Replace
them as a set if the clearances are outside the limit value.

1.

Measure the clearance “A” at 2 points or more diagonally oppo-
site using a dial indicator. And then calculate mean value.

2.

Measure the clearance “B” at 2 points or more diagonally oppo-
site using a feeler gauge. And then calculate mean value.

Baulk Ring Clearance for Triple Cone Synchronizer

Check the clearance between outer baulk ring, synchronizer cone,
and inner baulk ring as follows.

CAUTION:

The clearances “A”, “B”, and “C” are controlled with outer
baulk ring, synchronizer cone, and inner baulk ring as a set.
Replace them as a set if the clearances are outside the limit
value.

1.

Measure the clearance “A” at 2 points or more diagonally oppo-
site using a feeler gauge (B) when pressing outer baulk ring (1),
synchronizer cone (2), and inner baulk ring (3) toward gear taper
cone (C). And then calculate mean value.
