1st Shaft Assembly
1. Remove the bearing (1) and external circlip (2).
2. Draw out the 1st-2nd synchronizer unit and gears.
3. Remove the bearing (25).
4. Draw out the 3rd-4th synchronizer unit and gears.
(When reassembling)
• Be sure to assemble the synchronizer unit, set the teeth (28) on
the shifter (6) to the key (7) as shown in the figure.
• The directionality of couplings.
- Hydraulic shuttle model :
The both coupling (29) and (30), turn the longer boss side (D)
to the forward (F).
- Synchro shuttle model :
The coupling for 1-2 speed (31), turn the longer boss side (D)
to the rearward (R).
The coupling for 3-4 speed (32), turn the longer boss side (D)
to the forward (F).
• Apply transmission fluid to synchronizer unit.
• Apply molybdenum disulfide (Three Bond 1901 or equivalent) to
the inner race (23).
• Face the grooved side of thrust collar (24) to the gear side.
• Replace the external circlip (2) with new one.
• Adjust the side clearance (L) between external circlip (2) and
adjusting collar (3). Check the clearance (L).
