Hey dudes,

I have a type 1 AH code transmission. The cross shaft was all messed up when I got it, so I ordered a cross shaft bushing kit to set her right. This one...

Image may have been reduced in size. Click image to view fullscreen.

Well, everything accept the spring and set screw was wayyyy to small for the shaft. Good thing it was only 8 bucks Rolling Eyes

Any ways, I saved all the parts from the one that was on I pulled. The snap rings, washer, and bronze bushing with the ??plastic?? inner sleeve look like they are in good shape. The rubber bushing on the other hand...its dry rotting.

Also, there was only one rubber thing on the shaft I pulled out...arn't there supposed to be two?

What do I do about the rubber part?

I thought about using the rubber pieces that came with the new kit and stretching the living daylights out of them to fit them over the cross shaft. I'm just afraid that they will rip while on the shaft Confused

Your input is golden, thanks!

You have a 72 or later trans, these all had larger crosshafts, if you use a hd kit with large bronze bushing no rubber sleeves will be used

Yes, it is a 72 Transmission. How important are those rubber pieces, all it look like to me is that they keep the grease around the plastic part inside that metal bushing.

And whats this about the heavy duty kit?

The hd kit, or bushing, replaces the steel sleeve, plastic bushing, and rubber seals with a one piece bronze bushing

Weddle now has oil impregnated bronze cross shaft bushings in both 16mm and the later 20mm size.
These work better than the brass ones in a transmission that not seeing constant maintenance such a racing trans would see.

Scott,
What I was saying is that on a street car there really is not a way to regrease the brass bushing without taking it apart, (maybe a zerk fitting could be installed) so over time the grease dries out and shaft starts sticking or binds up.
So the oil impregnated bronze bushing makes more sense to use.
They work great in all applications.
In the early swing axles transmission for a time period VW used the oil impregnated bronze bushing for the cross shaft before changing to the plastic w/rubber bushings inside the aluminum sleeve.

Alright, thanks guys.

What about those rubber pieces inside. What should I do about those? Is it possible to just find some o-rings to fit in to hold the grease?

I agree 100 %, most silicone bronze bushings are impregnated any way, I was not trying to confuse the op by giving more options, my bad

Van,
Get one of these from Weddle Industries (805) 562-8600
Image may have been reduced in size. Click image to view fullscreen.
They come in both 16 and 20mm sizes.
What you have from your video from another thread is the 20mm size.
Make sure you have the inner snap ring and washer on shaft so it lines correctly.
These bronze bushings work great if using a stronger pressure plate, will help keep cross shaft from moving at angle when stepping on pedal.
Also make sure arms are welded on shaft for TO bearing. The stock welds can break loose.

It takes years, if not decades of daily use for the lube in there to dry out. As long as the mechanism is taken apart, cleaned and re-greased, you're good for many years.
I know a guy who rebuilds gearboxes and when he gets a trans, he grabs onto the arm and levers it against the spring. If it moves freely, he leaves it alone, not taking it apart to clean and re-lube it.

It all depends on how vehicle is being used on how long it will last.
Using it in dusty, dirty, muddy, and water such as were a Dune Buggy will go, things get gummed up faster then just driving on pavement.

Thanks jsturtlebuggy for 1, watching my silly little videos Laughing and 2, for your help. You too mcmscott.

...Say, if thats all it is, I could probably just make one of those bushings. I don't have access to the impregnated stuff, but a grease groove shouldn't be any problem to make.

A grease groove should help keep that stuff in there a long time.

Yeah, hmm...So I'm thinking that if it ever does dry out, then the set screw could be removed, and a zerk screwed in, give it a small pump, remove the zerk, and thread the set screw back in.

I have seen a lot of bug pack urethane bushings for the large cross shafts. Does anyone know about the quality?

I am also having trouble finding the smaller bushing for the other side of the cross shaft, the one thats pressed into the case. It is a bit sloppy. The shaft could wiggle around in it a little bit. It was minimal, but I think it could definitely be better.
