Synchro Component Assembly

SYNCHRO COMPONENT ASSEMBLY
The easiest method of assembling each synchro is to install the springs, struts and detent balls one at a time as follows:
1. Slide the sleeve part way onto the hub. Leave enough room to install the spring in the hut, and the strut in the hub groove.
2. Install the first spring in the hub. Then install a strut over the spring. Be sure the spring is seated in the spring bore in the strut.
3. Slide the sleeve onto the hub just far enough to hold the first strut and spring in place.
4. Place the detent ball in the top of the strut. Then carefully work the sleeve over the ball to hold it in place. A small flat blade screwdriver can be used to press the ball into place while moving the sleeve over it.
5. Repeat the procedure for the remaining springs, struts and balls. Tape, or a rubber band can be used to temporarily secure each strut and ball as they are installed.
