Engine mounts...

[Nogin]

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.

It's a common fault on these bikes unfortunately. Generally means the engine is scrap

dont see why this cant be welded, whats the casing made from????????

Can we have some pix please???

[redline]

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.

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

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

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

Surely if you can pull it off..............it's not very strong
