Synchro Sleeve and Hub Inspection and Reassembly

Synchro Sleeve and Hub Inspection and Reassembly
1. Inspect gear teeth on all synchro hubs and synchro sleeves for wear (rounded off corners).
2. Install each synchro hub (A) in its mating synchro sleeve (B), and check for free movement. Make sure to match the three sets of longer teeth (C) (120° apart) on the synchro sleeve with the three sets of deeper grooves (D) in the synchro hub.

NOTE:
^ If replacement is required, always replace the synchro sleeve and synchro hub as a set.
^ Do not install the synchro sleeve with its longer teeth in the 1st/2nd synchro hub slots (E) because it will damage the spring ring.
