wombat Posted February 8, 2011 Report Share Posted February 8, 2011 Ive found a long crack in the rear brake backing plate on my '74 TY250. It seems to be full thickness crack. Can this be welded or do I source another 1? Quote Link to comment Share on other sites More sharing options...

Can this be welded or do I source another 1? Hi wombat Any decent welding firm will be able to TIG [must be TIG, mind] weld that for you. Will then be a simple matter of dressing the weld for cosmetic purposes. If you don't know of a local company, put welding services or precision engineers into Yell.com and make a few calls. Do NOT let your mate loose on it who says "No problem, I can easily gas weld that for you...." If the crack goes through the pivot hole, make sure the bearing surface is aligned properly and be prepared to ream the hole slightly. One more thing, might be easier to look at the ads in "Classic Dirt Bike" as I'm sure you'd find a replacement from one of the companies who advertise there. Best wishes Will-in-the-mud.

ducman Posted February 8, 2011 Report Share Posted February 8, 2011 Ive found a long crack in the rear brake backing plate on my '74 TY250. It seems to be full thickness crack. Can this be welded or do I source another 1? Be careful the brakeplate is magnesium and needs a special system to weld.Magnesium burn's very well,remember taht.

triton Posted February 8, 2011 Report Share Posted February 8, 2011 I would source another one, mag not good for welding. If a TY175 is the same there is one on a popular auction site this is the item number 250769188664. Quote Link to comment Share on other sites More sharing options...
