NOTE: Hubs and sleeves have a master spline combination and can be assembled one way. The sleeves are further identified with a series of half moon notches which clearly identify which side of the assembly faces which gear. Ensure the slot in the hub aligns with the center notch on the sleeve.







9. Fit slippers and secure with a spring each side of the synchromesh assembly ensuring the step on each spring locates on a different slipper.

NOTE: 5th and reverse synchromesh hubs have different springs which are colored yellow.
