engine strengthening

Post  mickey c on Wed Jan 21, 2015 6:34 am

Hi again all
now my engine is stripped and clean, I've unfortunately found a crack that I need welding up.
Whilst its there, I thought I would have it strengthened underneath the gearbox area as apparently that's a weak spot; I'm going out to 130 odd cc so figured it makes sense.
I write because I am sure I have seen a picture of this done on here but cant for the life of me find it, can someone tell or show me where it is advised I get strengthened please?

Fine Line Welding 'up in hills'. 0161 430 5588

They do alloy welding and have done a couple of jobs for me. Welded my engine mounting on my GP and also a lug for my exhaust mount on my Lui.

thanks Ed
I found somewhere to do it; a motor bike shop in the city centre.
its knowing where to ask them to strengthen. I know its under / around the rear hub / gearbox area as I read of a weakness in that area but I could do with something specific to put a big X's on when I give it to them.
do you remember the thread where someone put a picture on showing where to weld please?

I remember it but can't find it either. I can point the area out to you but it's easy enough to work out - the cracking occurs where the end plate bolts on so its the opposite side of the casing to the thread holes. If you look at the casing there is a raised area where the layshaft and gear box sits. They had welded all around the area where it starts to rise if I remember the picture.
