G1 fixed sheave

[makobuggie]

Today i cracked my fixed sheave takeing the puller bolt out, i had it in a vice, a piece broke off were the belt rides on it, it looks like pot metal, do you guys think it can be welded? I dont want to buy a newone if i can get it fixed,the only way i got the bolt out was to drill 4 little holes thru the flat part and stand it up and screw it down to hold it from turning, whats the best way to get that pully bolt out? Thanks, i did get it out, it was almost all the way in.

do you have any pics ? pot metal would be hard to weld !

Engine or trans clutch? Some are alum and some steel, the alum will crack way easier. Sure you can weld up alum but you need a TIG or heliarc usually. I don't know if it would warp it, or how you could clamp it back in straight. It really needs to be true in how it runs on the belt. Most of the alum clutch parts are cast, but that does not make much difference far as welding it. You can machine the sheave back down on a lathe easy enough, but for the cost of a new one a lot of people just buy one. Plus they wear out you should mic the surface the belt rides on and see what is left. I measured a clutch that had holes in it and it was over .020". You can see how the belt dishes the surface in if it is worn a lot.

If it looks like pot metal then it's the aluminum type. If the crack isn't to big it might be salvageable. I'd be worried about the polished surface being "true" and wearing the belt or making problems when shifting. If it didn't actually break apart in two pieces then I'd weld it from the outside and be careful not to use too much heat at once, since it's alum best to leave that to an expert welder.

Sounds like it's time for a Plowman's Power Kit!

Mako, i did the same thing this past week and your right its cast or potmetal. The part that broke on mine was the lip the belt rides in so I took a file and filed it down to remove the sharp edge so it wouldn't knick the belt up and as of now it looks to be working perfectly. You may want to file the edges off it it isn't to bad and see how it works before replacing.. jusy my two pennies
