1979 Ariens 7hp- cocked pulley...

Model 924038

I have a drive pulley that's not perpendicular to the drive belt.
I tore it apart and discovered the pulley shaft 'egged out' the mount and that's why it's not inline. Wobbles when moved.

Any remedies? Brass sleeve? Oversize the hole in the bracket and tack in a sleeve? Cut bracket out and somehow bolt in a new one?

My buzz box welding is less than steller, so I would prefer a remedy that doesn't involve me using it on such a small bracket.

Thanks.

Without doing some welding, you could always connect a spring from the idler bracket to one of the bolts on the handlebar or engine mount, or even drill a 1/8 inch hole somewhere in the housing for the other end of the spring, so there is tension to draw the idler pulley straight in-line when engaged with the drive pulley.

I had this happen on one, I that I took apart, and welded it up, as well as another washer … … These units are built so well, that going for 50+ years causes some parts to just plain wear out …

BTW, I would also put some nice X-Trac and that machine as well, instead of the turf tires. ….. big difference.

So, I should get a bushing to fit the shaft and try to fit it in the bracket? Maybe put some jb weld between the bracket and the lip of the bushing?

That sounds too easy.. I hope that's the case.. cause I'm sitting here pondering cutting out the original bracket and bolting in a small homemade tube steel bracket that would have two holes for better support... But that will be time consuming and probably serious overkill.

Doesn't sound like what you are comfortable with, but myself I'd fill the hole with my MIG or TIG, and redrill the correct hole.

I'm comfortable with quick and easy fixes. Lol

I'm liking the bronze bushing idea.. with some jb weld .

Yes… Have a machinist make a bushing for you and you should be good… and in years from now, if there's some wear again, then just replace the bushing!
