BACK TO WORK
The big car show is over ( The Rodders Journal Hot Rod and Custom Revival )........it was damn cool . So it is time to get back to work on the Corvair. I went to the machinist today and picked up my axles. They turned out sweet. I went through a bunch of V8 vair posts looking for axle information and didn't find any. So I am going to try and get some of that information out to you.
You have seen the flanges for the axle attachment in several of the older posts. I could never quite get my head around how the whole trunion thing worked. Maybe this will help
These are the main pieces in my axles. The trunion is the big piece with the 3 leaf clover shape on the inside. The three stubs you can see on the end of the axle has a shitload of small needle bearing and round balls on each of the three points. this will give you the needed movement as the rear arms move up and down.
The round collar is to lock the u joint shaft to the splined axle. The u joint shaft is actually an output shaft from the back of a turbo 350 trans. We figured that should be more than strong enough for this application.
This shows how the three stubs fit into the trunion. This fit will provide a full 2 inches of in and out travel. More than enough for our total of 5 inches up and down trailing arm movement.
So this is the finished axle ready for the trunion balls and needle bearing and final assembly. The collar is a press fit over the u joint shaft. From the back of the trunion housing to the center of the u joint shaft.......10 7/16 inches total........just like we planned it
