Hello all, I have been using a Clarke135te for over a year now and it has been fine. I use it mainly for welding up my 18 year old lti tx1 taxi. The wire feed started making a funny noise and stopped working. When I stripped it down one of the plastic cogs has suffered some wear and is causing the problem. I have tried online to buy this part with no luck. It seems I have to buy the whole wire feed motor. Does anyone know of anyone who sells replacement cogs. Thanks in advance.
