So this happened on a friends '95 Summit 583. The bearing on the speedometer cable side seized up and did this damage. Bad, but not so bad to be difficult to repair.
The structure is still there for the bolts. The bolts are actually part of a ring, so I'll replace that ring I think other than that my only concern is blocking snow from getting into the bearing area and inside the tub (just below the clutches).
I have some other aluminum that is pretty close to the same thickness if I double it up. I'm thinking I'll cut a patch to fill the hole and then just attach it to a strip on the inside for a little bit of strength. It won't need to be really strong as the bolt-ring and structure would still take all the pull/weight/torsion.
First picture is from under the tunnel. You can see the bolt-ring was cut through. Second picture shows that the bolts are still supported pretty well.
Hardest part about this sled is the clean up. It sat for 5 years partially torn apart, evidently they couldn't figure out how to get the brake caliper off to pull the chain case off.
Lots of rusty parts and even the aluminum needs to be cleaned up.
I'm debating on whether or not to pull the motor apart. It seems to turn over fine and have good compression. Just 1478 original miles on it.
He also has a 95 Summit 470 that ran before they parked it, but it is seized up tight right now. I'll work on it after the 583.
What is interesting about both these Summits is the paddles are fairly small. From the band to the tip, they are probably 3/4" at best. My 94 Summit 583 they are about 1.25" - 1.5" tall.
