Inspect gear teeth on all synchro hubs and synchro sleeves for wear (rounded off corners). Install each synchro hub (A) in its mating synchro sleeve (B), and check for freedom of movement. Make sure you match the three sets of longer teeth (C) (120 degrees apart) on the synchro sleeve with the three sets of deeper grooves (D) in the synchro hub. Do not install the synchro sleeve with its longer teeth in the synchro hub slots (E) because it will damage the spring ring. NOTE: If replacement is required, always replace the synchro sleeve and synchro hub as a set. |
