Synchronizers Assemble 3rd/4th Speed Gear

Important: 

•	Only disassemble the synchronizer sleeve from the synchronizer hub if there is a suspected gear shift concern.

•	For installation alignment, scribe an alignment mark on the synchronizer hubs and synchronizer sleeves before disassembling.

•	Mark the synchronizers clutch gears and the blocking rings with the corresponding gear, for correct diagnostic inspections.

•	Install the synchronizer components in the same location, if reusing.

1. Lay the synchronizer hub on the 3rd speed gear synchronizer blocking ring and clutch gear. The ring and gear will hold the hub up.
2. Slide the synchronizer sleeve on the synchronizer hub.

•	Align the large tooth with the large slot in the sleeve.

•	The sleeve can go either direction, if it is not marked.

3. Using a small screwdriver, install the 3 springs and the 3 inserts.
4. Move the sleeve to the neutral position, to hold the springs and inserts in position.

Synchronizers Assemble 5th/Overdrive Speed Gear

Important: 

•	Only disassemble the synchronizer sleeve from the synchronizer hub if there is a suspected gear shift concern.

•	For installation alignment, scribe an alignment mark on the synchronizer hubs and synchronizer sleeves before disassembling.

•	Mark the synchronizers clutch gears and the blocking rings with the corresponding gear, for correct diagnostic inspections.

•	Install the synchronizer components in the same location, if reusing.

1. Lay the 5th speed gear assembly, with the gear side down, on the workbench.
2. Slide the synchronizer sleeve on the synchronizer hub, with the tapered side of the sleeve towards the gear.
3. Using a small screwdriver, install the 3 springs and the 3 inserts.
4. Move the sleeve to the neutral position, to hold the springs and inserts in position.

Synchronizers Assemble 1st/2nd Speed Gear

Important: 

•	Only disassemble the synchronizer sleeve from the synchronizer hub if there is a suspected gear shift concern.

•	For installation alignment, scribe an alignment mark on the synchronizer hubs and synchronizer sleeves before disassembling.

•	Mark the synchronizers clutch gears and the blocking rings with the corresponding gear, for correct diagnostic inspections.

•	Install the synchronizer components in the same location, if reusing.

1. Lay the 1st/2nd speed gear assembly on the 1st speed gear synchronizer inner and middle rings. The rings will hold the hub up.
2. Slide the synchronizer sleeve on the synchronizer hub.

•	Align the sleeve to the hub.

•	The sleeve will fit in only one direction on the hub.

•	The tapered side of the sleeve faces up, or toward second gear.

3. Using a small screwdriver, install the 4 springs and the 4 inserts.
4. Move the sleeve to the neutral position, to hold the springs and inserts in position.

Synchronizers Assemble Reverse Speed Gear

Important: 

•	Only disassemble the synchronizer sleeve from the synchronizer hub if there is a suspected gear shift concern.

•	For installation alignment, scribe an alignment mark on the synchronizer hubs and synchronizer sleeves before disassembling.

•	Mark the synchronizers clutch gears and the blocking rings with the corresponding gear, for correct diagnostic inspections.

•	Install the synchronizer components in the same location, if reusing.

1. Lay the reverse speed gear assembly, with the reverse gear down, on the workbench.
2. Slide the synchronizer sleeve on the synchronizer hub.

•	Align the sleeve to the hub.

•	The sleeve will fit in only one direction on the hub.

•	The tapered side of the sleeve faces toward reverse gear.

3. Using a small screwdriver, install the 3 springs and the 3 inserts.
4. Move the sleeve to the neutral position, to hold the springs and inserts in position.
