INSPECTION
1. Clean the assembly with a suitable solvent and dry the parts using compressed air.
2. Inspect the shift spool assembly for damage. Small nicks and burrs may be smoothed.
If any parts are damaged or worn excessively, it will be necessary to replace the com-
plete shift spool assembly. Individual parts are not available for the assembly.
3. Inspect the shift spool for wear in the area where the shift crank comes into contact.

4. Inspect to insure that the spool spins freely (it may be helpful to lightly tap the castle
nut end of the shift spool against a firm surface to align the internal parts).
5. Inspect to insure that the spool has 0.002 - 0.010 (0.05 mm - 0.25 mm) end play. This
end play may be achieved by turning the castle nut clockwise down until it is snug and
then backing off the nut counterclockwise to the first cotter pin slot.
