QUOTE(McMark @ Nov 17 2006, 02:42 AM)  Welding has the potential to protrude into the tube as it melts. Any protrusion into the tube will wear cables FAST! Welding clutch tubes makes me nervous, but it's really the best solution as long as you're careful. The brazing is also one of the reasons that a fender washer is necessary at the firewall. You can weld over brazing, so in order to repair that section you either have to redo the braze, remove all the brazing material then weld, or use a fender washer that extends beyond the brazing. (IMG:style_emoticons/default/agree.gif) I was able to build my weld out far enough past the brazing. Also, I used a piece of flexible copper (the kind for a regrig ice maker) from HD and ran it through the tube to keep the weld from protruding into the tube. My PO had done a hackjob clutch tube repair with bailing wire. There was already a small hole cut in the center tunnel. I added tabs to the clutch tube and welded the tabs to the floor and wall of the tunnel through the shifter hole and the hole the PO hacked in. I probably could have done it just through the shifter hole and been fine. Right now the whole deal is untested though. The car is still on jackstands. (IMG:style_emoticons/default/welder.gif) |

QUOTE This is true, EXCEPT that they were never welded. No tube is welded to the car. The clutch tube, the engine lid release tube are all brazed.

You are correct. Those spots are all brazed in place. I still couldn't get to the third spot that everyone seems to ignore. I forgot. Mine was so loose I could push the tube far enough forward that I ground the brazing off the firewall when I welded my washer in place. |
