So here we go with the synchro bits.

As before all the bits are cleaned and oiled before fitting. I placed the three springs into the holes in the hub and then fitted the hub into the outer housing, make sure to line up the slots for the baulk rings. The ball bearings will sit in the small countersunk ends of the spring holes, see the picture below.

Once all three ball bearings are in place it is possible to gently squeeze them into the holes while pushing the two housings together. It will go in all of a sudden so be prepared. dont stop pushing or let go of the ball bearings just be confident and press it home. Then place one of the baulk rings in the gear as shown in the bellow picture.

Now slide the whole assembly onto the shaft.

Next its time to install 1st gear. First place the gear bearing carrier onto the shaft. Note in the picture that I have placed the baulk ring into the syncro hub.
Then place the needle bearing and 1st gear on the carrier, you can see on the picture that the carrier is not all the way down the shaft. this is because its a really tight fit and you need 1st gear on to give you the leverage to push it home.

So the next bit is to build the syncro hub for 3rd/4th gears which goes on the other end of the shaft to the one ive just done. I am not going to post pictures of the 3rd/4th syncro build as its exactly the same to put together as the 1st/2nd syncro.
Anyway here it is all built and on the shaft. (Dont forget the baulk rings)

And this is how it should look now with the first gear pushed fully down onto the shaft

I have been useing loads of oil on the parts as ive been putting this together. Now that this bit is complete i will submerge it in a tin of clean oil to keep the moisture off.
Err... i know I shoudnt blow my own trumpet but im really pleased with how its gone so far.   Although i dont think Guess works has anything to worry about.
Next its the 1st motion shaft, but thats me for now.
