14. Install 6th needle bearing, 6th input gear, 6th baulk ring onto 6th

input gear bushing and then press in 6th input gear bushing onto
input shaft using the drift [SST: ST33200000].

15. Install snap ring onto input shaft and make sure that end play

(gap between snap ring and groove) of 6th input gear bushing
satisfies the standard value.

• If measurement is outside the standard range, select snap

ring.

CAUTION:

Never reuse snap ring.

16. Press in input shaft rear bearing using the drift [SST:

ST30901000].

CAUTION:

Install input shaft rear bearing with its brown surface facing
the 6th input gear side.

17. Press in input shaft front bearing using the drifts.

18. Install oil channel onto input shaft.

19. Check end play of 3rd, 4th, 5th, and 6th input gears.

Inspection

INFOID:0000000001034958

INPUT SHAFT AND GEAR

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

SYNCHRONIZER

Synchronizer Hub and Coupling Sleeve

Check items below. If necessary, replace them with new ones.
• Damage and excessive wear of 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 Single Cone Synchronizer (4th, 5th, and 6th)

Push baulk ring on the cone and measure the clearance between
baulk ring and cone. If measurement is below limit, replace it with a
new one.

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.

BEARING

Check items below. If necessary, replace them with new ones.
• Damage and rough rotation of bearing
