SteveA Posted July 14, 2008 Share Posted July 14, 2008 I am doing some chassis repairs on a Series III Lightweight, on the main chassis rails under the rear loading area. I have done the passenger side quite easily, but the drivers side main rail also houses all of the wires for the rear lights, do you have any tips on how best to weld repair the chassis rail, while making sure the cables do not get damaged? Thanks, Steve Quote Link to comment Share on other sites More sharing options...
Les Henson Posted July 14, 2008 Share Posted July 14, 2008 You can either pull the wiring out of the chassis and then cable tie it to the top of the chassis rail or cut out the rust and use some stiff wire or similar to keep the cable on the opposite side of the chassis. This is what I do. It's ok with electric welding, but gas is a different matter - due to the amount of radiant heat generated. Les. Quote Link to comment Share on other sites More sharing options...
sotal Posted July 14, 2008 Share Posted July 14, 2008 You could pull the wiring out then feed it back through afterwards, be prepared to swear a bit as you feed it back, it took me quite a few attempts to get it back through! Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted July 14, 2008 Share Posted July 14, 2008 When I did my lightweights quarter chassis I managed to thread some old caravan waste pipe that I had slit down the middle over the wires to keep them in a bundle -the pipe is corrugated and therefore you are able to move it around inside the chassis to keep it away from the side you are welding. You could use anything really -old hose pipe if it is big enough for example.... Once done you just pull the hose off the wires and they are all still in place ready for reconnecting -job done Quote Link to comment Share on other sites More sharing options...
Littlun Posted July 16, 2008 Share Posted July 16, 2008 I remove it from the chassis and the cable tie to the floor so it doesn't impede rust protection and further work to the chassis. Quote Link to comment Share on other sites More sharing options...
david1701 Posted July 17, 2008 Share Posted July 17, 2008 what about tieing some string to it then pulling it back out, it doesnt matter if the string gets damaged does it? and it would be easier to pull back thro then, unless of course the string got welded to the chassis Quote Link to comment Share on other sites More sharing options...

It's OK if you know the state of the inside of the rails, otherwise................ Quote Link to comment Share on other sites More sharing options...
david1701 Posted July 22, 2008 Share Posted July 22, 2008 good thought, i was thinking of how i have routed cables in houses, but i never considered the impact of sharp bits of chassis and tired bits of wire Quote Link to comment Share on other sites More sharing options...
