"4th is grinding and second wont go in half the time due to it popping back out."

Customer is getting a basic rebuild, steel 3,4 shift fork, 3,4 billet struts.

Rebuild kit is $199 That contains blocker rings, C-springs, high hat, Synchro keys, front and rear seals, and fork pads.
Steel fork is $49 To replace the aluminum piece.
Billet struts $99 for a set of 3. These replace the stamped steel synchro keys with solid billet steel pieces.

We cancelled the Billet struts because there was gonna be a 2 week waiting period.

Here we go.:)
Starting position.

What they are supposed to look like. These are case magnets that sit in the bottom of the case.

Where those big metal chunks came from. Here is the rest of it.

This came from 3,4 assembly. As you can tell, it's hosed.

Here is the groove that can cause the "bending" of the shift fork.

Next to the steel one.

You can see the wear and tear here on the pads.

New parts, old parts. You can see the wear on the old ones to the right. These blocker rings start to rub against the gear itself.

Here is the old blocker ring. You can see just how close it is to the gear.

And the new one here, see the increase in the gap.

Carbon fiber/kevlar and the stock paper lined one on the right.

You can see the pattern from the stock blocker rings here on the right. The new one is on the left.

This is what starts to happen when it becomes hard to get in gear or forcing into gear over time. Grooving...

Re-assembly with new parts in place.

A little secret I came across when putting the main case back on. It will want to push down the shift forks and knock things out of alignment. I took a rivet and cut it with a dremel and placed it under the 3,4 fork pictured here. When the case comes down it will keep the fork in place. I use a pen magnet to pull it out later.

Wow, man it is a wonder that it even would go into gear at all...good work!

[Warp10]

Looks very good. When I pulled mine apart, I did noticed some moisture buildup under the 5-6 gears as well. Not as muched as showned here but a little notheless.

Good to see you have another successfull T56 rebuilt under your sleeve NBMWSsix. :thumbup:

The 5,6 gear is steel and not a billet like the others so it's more prone to rust. When doing the rebuild I clean everything real well and use a small wire brush to clean out the inside of the gear and the shaft itself. Then I coat everything in tranny fluid to protect it while it's out.


Thanks for the nice comments. He should have it back tomorrow and should be very happy. Then I will know and can relax. I get giddy just waiting to see how it worked out. It reminds me of when I first did mine and put it in. :)


And just to let you guys know. When I do a rebuild I take pictures to document everything and send those pics in a cd for them. So the customer can see what I found. I will also send broken parts and replaced parts back to the customer if requested. I also guarantee my work.:cool:

No. the endplay of the input/ mainshaft must be setup if you service any of the related bearings. Same goes for the countershaft. However, unless bearings need replaced, you leave them alone.
