This is off my Massey 12, The cast broke when trying to remove it the stupid way (Hammer) ended up buying a real puller so no more of this happening, But how can I put these parts back on?

I am inclined to say that a replacement is in order. Welded will eat belts and throw the balance off. Chalk it up to education and move on.

The pieces could be welded back on with nickel rod, but I recommend either replacing the pulley, or just rounding the inside edge of the breaks & using as is. There won't be enough difference to cause any noticeable balance issue, and if rounded, no harm will be done to the belt. I've run chipped out pulleys for years with no problems whatsoever.

Is that pulley off of a gear drive, Vari-drive?

^ Yes it is, I have a hard time finding a replacement (need two, one for the 10 and now this one) And I am beyond tight on cash. Hence why i was hoping it could be fixed

I agree with Daniel--just round the rough edges slightly to avoid chewing up your belt and run with it... There isn't a large area broken out so you won't have a problem.

File, grind them, and you should be O.K. Only replace if it eats belts. Proper tool for the proper job. Did I just say that? I need to listen to my own advice.

For what it's worth ...
I've repaired cast pulleys with a broken area like that before.

Grind the edges of the broken out area and the mating pieces so there is "V" area on boths sides at the break line.
Clamp the pulley and the broken out pieces to a flat piece of metal and braze them together.
Then turn the pulley over and braze the other side ( do this carefully so you don't melt out the braze that you had just put in ).
Put the pulley in a lathe and turn the brazed area down until it is flush with the surface.

This repair works fine on a pulley that just has a small area like that broken out.
If the broken area is larger, than it really needs to be tig welded and that gets much more envolved.

Been there, done that! :mad2: Its very frustrating, but I agree with the others, take off the sharp edges, and you won't have a problem. The drive pulley on my Wheel Horse is missing a larger piece than that, and I've never had a problem. :thumbs:
