Getting the car ready for the drags?? Transmission looks good Tom. Are you going to change the rear end gear ratio or just beef up the differential? Looking Good.

Exotica

Keeping 3.42s. I changed to the MN6, though since I wanted slightly longer gears.

How does a synchro work?

ragtopws6

The synchronizer's job is to bring the next gear (up shift or down shift) up to speed so the shaft and the gears are the same speed. The synchro has few parts. The synchro hub (splined to the shaft) and synchro ring (slides over the hub in either direction) is held in place by the keys/retaining spring. The outter ring slides over and first engages the blocker ring (this has friction material that aids the gear up to speed) and then the engagement teeth on the gear. Take a look at the pictures below and see if you can understand it.

This is a comparision of T56 synchro on the left and TR6060 on the right.


This shot shows how the outter ring of the synchro slides back and forth.


This is a synchro sandwiched between two gears.


This is a side of the gear that faces the synchro. If you look close, you can see the little engagement teeth just above the main gear teeth.

I forgot to include this blocking ring/cone.

Exotica

Further buildout of my differential should be completed today. It already had hardened shafts but now is getting carbon fiber clutch packs and C6 pinion support. Can't wait to install it!

Cleaning the diff as I type. WOW, the diff needed ALOT of cleaning. Can't post before pics due to D rated content. D=dirty! LOL. Diff assembly pics will be loaded this weekend.

Nice builds, do you do this in your kitchen or something? lol

ragtopws6

LOL, thanks. I usually do it in the garage but it's been so damn cold here, I decided to move it indoors. I have a fireplace, big screen TV and WARMNESS!!!
