I have a 1970 914-4 that has a cracked firewall due to a loose clutch tube. Should I welded in a reinforcement plate (16 ga. steel) around the clutch tube hole?
If I switch engines to a six - will the reinforcement interfer with a firewall motor mount? |

I normally build a small square scab plate depending on how bad the "tear" is on the firewall. The problem is: they brazed that tube in... so you have to grind away ALL the brazing before welding. I make my scab plate with a hole in it so it slips over the tube end. I then weld around the scab plate and then arond the tube. I stick a old Phillips head No.2 screwdriver into the clutch tube when I weld around it so my weld doesnt penetrate the tube. Obviously using something like BRASS would work.. but it doesnt take much heat to weld that tube up to the plate/firewall.
I weld up the cracks first... then add the scab plate... B |
