M/T Synchro Sleeve and Hub Inspection and Reassembly
|1.||Inspect gear teeth on all synchro hubs and synchro sleeves for rounded off corners, which indicate wear.|
|2.||Install each synchro hub (A) in its mating synchro sleeve (B), and check for freedom of movement. Be sure to match the 3 sets of longer teeth (C) (120 degrees apart) on the synchro sleeve with the 3 sets of deeper grooves (D) in the synchro hub. 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.|
NOTE: If replacement is required, always replace the synchro sleeve and synchro hub as a set.
