(IMG:http://www.914world.com/bbs2/html/emoticons/lol2.gif) Nope.. gonna run it like that..... Imagine the cloud of smoke behind my car from all the gear oil it would be slinging........ (IMG:http://www.914world.com/bbs2/html/emoticons/chairfall.gif)



Actually, the transmission case in the pictures suffered from half shaft trauma. The cv bolts backed out and the half shaft spun around at speed and knocked a hole in the case. I cut the part out for the fork adjustment. That case is now just a fork adjustment jig.


You should see the side shift console...... (IMG:http://www.914world.com/bbs2/html/emoticons/icon8.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/barf.gif)

Betty just came in for lunch... She is just that good with photoshop so she made a transparent transmission for me...

She also suggested "transparent aluminum" to fix it (Geek Check).....

I figure I can fix it like Charlie Davis fixed his transmission.... Duct Tape!!!!!

Thanks Bob

The photoshop was a joke. The cutaway trans case exists for real. It makes a wonderful shift fork alignment jig. (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)

But I can't post any more pictures. I took the gearstack out and assembled my transmission.

Clay,

I'm confused...
why do you need an adjustment jig?

can't you just align the shift forks with an alignment tool when the stack is pulled out?

Yes, You can align the forks with the alignment tool with the stack out. But can you guarantee that the shift forks are in the right place for the 30+ year old intermediate plate. I have built multiple 901s, and I have almost always had to go back in and readjust the forks so they shift right. Usually, its 4th/5th that is misaligned. The intermediate plate wear causes the rods to get out of position, and the finger on the shift console will slip past the 4th/5th fork without disengaging 4th gear. then you have to pull the stack back out of the car to readjust.

Using the cutaway trans case, I can verify that I have the correct alignment on the forks, by installing the shift console and running the trans through all the gears. Now I know it's going to work right the first time........



Oh, and Aaron... (IMG:http://www.914world.com/bbs2/html/emoticons/flipa.gif)

I took the pictures free hand. If I had known you wanted to make an animation of them, I would have just taken a movie of it.
