Nogin Posted August 9, 2011 Share Posted August 9, 2011 Been offered a tatty GS500 that would make a great winter hack, but the front engine mount has broken on the engine block.It runs a treat but also needs a new exhaust.The question is does anyone know if the engine can be welded? assuming the missing mount is an MOT failure.

Guest Hodgy Posted August 9, 2011 Share Posted August 9, 2011 It's a common fault on these bikes unfortunately. Generally means the engine is scrap Quote Link to comment Share on other sites More sharing options...

redline Posted August 10, 2011 Share Posted August 10, 2011 course it can be welded. take the motor minus oil etc and have a welder fix it up, depending on the mount they can even make a new mount out of weld. it wont cost much but theres some work involved in getting the motor out and over to a welder.

Fozzie Posted August 10, 2011 Share Posted August 10, 2011 If the mount snapped wouldnt welding it mean it will snap quicker next time? A new mount or making one up that works would be a good option though Quote Link to comment Share on other sites More sharing options...
Roadtorque Posted August 11, 2011 Share Posted August 11, 2011 Engine castings & the likes, welding is not a viable repair, as the casting has lost it's integrity, A weld will just give way again,, Quote Link to comment Share on other sites More sharing options...
indie Posted August 11, 2011 Share Posted August 11, 2011 Engine castings & the likes, welding is not a viable repair, as the casting has lost it's integrity, A weld will just give way again,, sorry disagree fully, ive spent years having to repair and reweld smashed alumininum forming tooling on papercup machines and sweet wrapping machines, never had a broken weld ever, for their size these components have to handle far more stress than a bike engine bolted into a frame, ive also welded cast engine casings on both cars and bikes and never had a failure, welding any casting with a tig set is an art that not everyone can pull off though Quote Link to comment Share on other sites More sharing options...
sparkeh9 Posted August 11, 2011 Share Posted August 11, 2011 I always thought the weld it's self was meant to be stronger than the materials it's joining? Quote Link to comment Share on other sites More sharing options...
indie Posted August 11, 2011 Share Posted August 11, 2011 I always thought the weld it's self was meant to be stronger than the materials it's joining?when welding cast, yes for sure the weld will be stronger, with cast materials its all about getting the material up to temperature before you weld it, keeping it clean, taking into account the shrinkage rate and allowing it to cool slowly at a controlled rate. You weld cast material cold and theres a good chance it will fail, any dirt, it will fail Quote Link to comment Share on other sites More sharing options...
