Take a close look at the front of the block where the generator rests, if the bracket was broken or loose this area can be worn. Two of the three that I have seen loose or broken were worn very badly in that area and the other had some wear. With the generator mount bolted in place and the generator installed with out the belt check for clearance at that point. If there is any clearance at all it will allow the belt tension to flex the bracket even if properly adjusted. A shim could be made out of aluminum, copper or a hard rubber to insure there is no movement there. That would spread the load as far forward as possible and lessen the "lever arm moment" that the belt pull has on the generator and bracket assembly. And it would be easier than fabricating a bracket arm.

Anything to help spread the load....but really, if the belt is adjusted properly you should never have a problem...

I have drilled holes in the channel portion of the frame under the top tube/backbone (under gas tank) in direct relationship to the rear holes in the generator mount designed for the plastic cover. Then I fab two flat strap steel brackets to mount the rear portion of the generator bracket to the frame, helping to offset the front loading of the belt tension, which I feel is the main reason for mount failure. It also relieves some pressure from the engine case bolt hole mounts. If only MG engineers would have spread fore & aft the motor case mounting holes!!
