>>M<< Synchronizer Ring Installation

CAUTION: There is a 5th speed synchronizer ring and a reverse synchronizer ring. Be careful not to confuse the two when installing, as a mistake will affect the shift feeling.
  1. Check for the presence of identification notches on the synchronizer ring.

    No notches: 5th speed synchronizer ring 

    Three notches: Reverse synchronizer ring 

  2. Install the synchronizer ring so that it fits completely over the machined cone of the gear.
