NOTE: If the spool spins freely and has the proper clearance, it will not be necessary to
disassemble and reassemble the spool. If the spool does not function properly, proceed
with the following disassembly procedures.
SHIFT SPOOL DISASSEMBLY
NOTE: Disassembly of the shift spool is for cleaning and inspection of the internal parts
due to an improperly functioning shift spool assembly or debris in the gear housing and/or
shift spool assembly. Individual components for the shift spool are not available as re-
placement parts. If the shift spool does not function properly and the following cleaning
and adjustment procedures do not correct the problem, it will be necessary to order a new
shift spool assembly.
1. Remove and discard the cotter pin.
2. Remove the castle nut and spool.
3. Clamp the spool in a vice being careful not to damage the spool.
4. Unscrew the retainer.
SHIFT SPOOL REASSEMBLY
1. Place the shift spool onto the shift spool shaft.
2. Screw the castle nut down until it touches the washer and a slight resistance is felt.
3. Loosen the castle nut until the cotter pin slot of the nut is aligned with the hole in the
shaft. If, when the castle nut is screwed down, the cotter pin slot is already aligned
at the hole in the shaft, back the castle nut off until the next available slot in the nut
is aligned with the hole in the shaft.
4. Insert a new cotter pin and bend ends of the cotter pin in opposite directions.
5. Verify the spool has 0.002 - 0.010 in. (0.05 mm - 0.25 mm) end play. If it does not, read-
just the castle nut again.

6. If this adjustment did not produce the desired results it will be necessary to disas-
semble, clean, and reassemble the shift spool assembly. If the spool assembly has
already been disassembled and cleaned it will be necessary to replace the shift spool
assembly.
