toro mower pully

[wfw]

I have an old toro 8-32 lawnmower that sheared the pully at the bottom of the engine crankshaft. the pully has the key built into it so you have to replace the pully whenever this happens. they want 95 dollars for a new pully, moweris old so I son"t want to put that much into it. It as a double pully to power the transmission and blade. anyone know a lawnmower junkyard in the Winston-Salem nc area? any help or advice is appreciated. Thanks

Frank

Upgrade to a new mower and retire your old one. Parts are only going to get more expensive in the future. Or you might just have to go buy a new pulley. Good Luck

Try going to a local bearing supply dealer,tractor supply,grainger,mcmaster etc & get 2 fixed bore pulleys/w set screws,either stamped steel or cast iron of the size & bore you need(probably 1",but measure shaft od to be sure)also a pc of key stock(12")to match eng & pulley keyways,use old pulley as a guide as to setting on eng shaft & spacing between each,install old bolt & washer in end of shaft as a stop in case they loosen up,they will only drop to bottom of shaft instead of flying off.

Real question is WHY it sheared - it should never shear under normal use. Something has to be way out of line, binding or you hit something with it.

not sure why key sheared, i did not hit anything, I did change the engine two years ago, but shaft is the same size, the bolt holding the pully in place was tight,

Joe, I like your idea very much, thanks for the advice, I might use a piece of pipe as a spacer between the pullys.
