Examination
1. Check all hubs and synchronizer cages for rounded gear teeth, indicating wear.
2. Insert the hubs into their respective synchronizer sleeves and check if they rotate freely.
Note: Synchronizer cage and hub must be replaced together.
Installation
When assembling the cage and synchronizer hub, insert three pairs of longer teeth (offset by 120 degrees) on the synchronizer cage into three deeper grooves on the synchronizer hub.
Warning! Do not insert the synchronizer sleeve with long teeth into the grooves of the 1st/2nd gear synchronizer hub, otherwise you will damage the snap ring.
