New to me M7, and a motor mount problem

[ippielb]

Just bought this M7 on tuesday. Looked it over, but i missed one thing when i looked it over. I rebuilt the motor with new pistons, and all new seals. Went to put the motor in tonight and found this.

The front motor mount of the PTO motor plate is egged out. I'm thinking i'm going to get a new carriage bolt, then get my mig welder and fill in the egged section around the bolt since you can't weld steel to aluminum with fusion welding. OR do you think it would be better to just fill the hole and then drill a new one to hammer the new carriage in? Here's pictures of how it's suppose to look(off my firecat)

Another question is how was the motor able to move enough to do that? Isn't there two mounts on that side?

Yes that's the motor plate side so there's two. I'm thinking that the nut wasn't torqued and the stud backed out and it just vibrated the hole open. Both mounts in the plate are good still.

Here's the fix. I've never welded aluminum before, and never used a spool gun before.

Before

Welded

Finished

Motor mount works like a charm. New can on it and its loud. Steers awful though. Needs more ski pressure.

I have a set of Simmons gen 1 ski's I'm assuming they would be better? I know my ski's on my snopro 440 and my 600 mod are awesome for floatation and steering.
