1. Inspect gear teeth on all synchro hubs and synchro
sleeves for rounded off corners, which indicates
wear.
2. Install each synchro hub in its mating synchro
sleeve, and check for freedom of movement.
NOTE: If replacement is required, always replace
the synchro sleeve and synchro hub as a set.

Each synchro sleeve has three sets of longer teeth (120
degrees apart) that must be matched with the three
sets of deeper grooves in the synchro hub when
assembled.
NOTE: Installing the synchro sleeve with its longer
teeth in the synchro hub slots will damage the spring
ring.
