Disassembly

Transmission













WARNING: Do not breathe dust or use compressed air to blow dust from storage containers or friction components. Remove dust using government-approved techniques. Friction component dust may be a cancer and lung disease hazard. Exposure to potentially hazardous components may occur if dusts are created during repair of friction components, such as brake pads and clutch discs. Exposure may also cause irritation to skin, eyes and respiratory tract, and may cause allergic reactions and/or may lead to other chronic health effects. If irritation persists, seek medical attention or advice. Failure to follow these instructions may result in serious personal injury.

NOTE: For additional information on component views and base part numbers, refer to Transmission Assembly.

26. NOTE: Note the position of each synchronizer ring component before removal.

Remove the 1st gear synchronizer ring assembly.

- Inspect all synchronizer ring components for wear or damage. Install new components as necessary.





27. NOTE: Slide the synchronizer sleeve up while removing the pressure pieces.

Remove the 3 pressure pieces.





28. NOTE: Index-mark the synchronizer sleeve to the synchronizer hub before removal.

Remove the 1st/2nd shift fork, the 1st/2nd shift rail and the 1st/2nd synchronizer sleeve.

- Inspect the 1st/2nd shift fork and the 1st/2nd shift rail for wear or damage. Install new components as necessary.

- Inspect the 1st/2nd synchronizer sleeve for wear or damage. Install a new 1st/2nd synchronizer assembly as necessary.





29. Remove the magnet.





30. Remove the 2 bolts, spacers, spring and the interlock plate.





31. Remove the 3 center support bolts.





32. Remove the 1st/2nd synchronizer hub snap ring.





33. NOTICE: The center support must be pulled up evenly or damage to the center support or transmission case can occur.

Using the Push/Puller Set, Step Plate and the Synchro Gear Pack Remover under the center support pull off the center support, 2nd gear and the 1st/2nd synchronizer hub.





34. NOTE: Note the position of each synchronizer ring component before removal.

Remove the 1st/2nd synchronizer hub, the 2nd gear synchronizer ring assembly and the 2nd gear.
