MAINSHAFT AND 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.

17. Press in mainshaft rear bearing using Tools.

18. Install mainshaft C-ring onto mainshaft and check that end play

of mainshaft rear bearing satisfies the standard value. 

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

shaft C-ring.

Inspection

INFOID:0000000004201606

MAINSHAFT AND GEAR

Check items below. If necessary, replace them with new ones.

• Damage, peeling, dent, uneven wear, bending, and other non-

standard conditions of the shaft.

• Excessive wear, damage, peeling, and other non-standard condi-

tions of the 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.

MAINSHAFT AND GEAR

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 Triple Cone Synchronizer (1st and 2nd)

• 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 two points or more diagonally

opposite using a feeler gauge (B) when pressing outer baulk

ring (1), synchronizer cone (2), and inner baulk ring (3) toward

gear taper cone (C). Then calculate mean value.

2. Measure the clearance “B” at two points or more diagonally

opposite using a feeler gauge. Then calculate mean value.
