Help! Shift Rod Removal Need to Weld Crack

[mjedude]

I just purchased a 1980 911sc coupe, my first Porsche, and I am currently in the process of installing a short shift kit. Also I am replacing all bushings. While doing so I have discovered that the end of the shift rod (end that goes inot the shift rod joint) area where the narrower part of the shaft steps up to the full diameter of the shaft there is a crack on the factory weld. I am wanting to tack it with a mig welder, I could weld the shaft while the shaft is sitting in the tunnel but I prefer to remove it fron the car.

It seems that the end of the shaft is just pressed in and is held in place by a tacke weld. Is this correct??

How do I remove the shaft from the car??

Also, can anyone tell me if the original weld is from the factory??

Thanks,

Miles

Are you sure you are not looking at "J-B Weld" two tube mix epoxy? It's gray and blobby looking, not too unlike a tarnished braze weld.

I don't have much background on this stuff, but a Karmen Gina owner I know fixed his carb with it.

I now have it on my Siene shifter along with the provided clamp - time will tell.

Miles,

The original fabrication of this tube was a swaged down end, press fit slug with the 15mm Ø feature for the shifter socket, then a rosette weld through the tube onto the slug.
The tube is then sanded, to flush the weld and allow the tube to run in the bush.
I have seen many crack, I have also seen a skillful tech repair one in the car. Be careful there is a plastic fuel line running inside the tunnel about 2" from where you would be welding.
We overhaul the tube (out of the car) by seam welding the end of the tube to the slug, it eliminates the problem.

Yes, I prefer to weld it out of the car for the reason location of the fuel lines.

How do I remove the shift rod from the car??

Thanks

Miles,

You have to drop the engine and transmission to remove the tube - it goes backwards out of the tunnel.

Dang, that is a lot of work, good luck.

Thanks for everyone's help!

I managed to tack weld it in place at two spots. Placed some wet fire blanket under the shaft into the tunnel.

Tip end is very sturdy now, prior, the crack on the joint added to the existing slop.
