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)

Best would be to tig it and re-drill. You could try JB weld and let it set up with the bolt in.

I just have a mig and spool gun with gas. It should be good enough, better then JB weld that's for sure. Is the exact spot for the motor mount need to be precise with the centre to centre/clutch alignment?

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

Before

Welded

Finished

Looks good and deff better than JB Weld. I've done similar repairs before, I'll fill and then drill but then weld a large washer on and then mill off the thickness on the motor mount or bushing.

Looks good man. Don't see why you would have a problem with that!

Rebuilt the motor and put on the new can. This thing steers like a cruise liner, absolutely no ski pressure it feels like if I lean forward on the front ski's it can turn better, but if not can't turn hardly. My snopro 440 can turn around in 1/4 of the space.

You can tighten the shock in skid to help a little but that the m7 ride the track.

You want to loosen it for more ski pressure. your getting the front portion of the skid to collapse more so your nose actually points slightly more down.
