Motor Sleeve (bushing)

I think you have whats called a a sleeve bushing
is that one not usable with a little TLC?

You need a pulley bushing. Sold most places that sell pulleys. That said you have a real thin one there and may not be standard. You sure that the pulley is not an inch or metric ?

That would be a 1/32" thick bushing......roll it up out a coke can. But, your #1 picture says otherwise. Have another look at your measurements.
Like that dial BTW.

kind of a weird failure there between shaft and pulley. Is that maybe the pulley set screw was walking?

It looks like the sleeve/bushing eliminated the key fit between the shaft and the pulley and relied only on the set screw to transmit power?
Notice the round set screw indent on the shaft at about the 3 o'clock position relative to its keyway. Also the hole thru the sleeve/bushing and the obvious spin damage from a loose set screw.
The McMaster Carr link for these indicates they are for low torque applications and indeed show a hole thru the sleeve for a set screw.

Not sure how long it ran like that but maybe flip it end for end and drill a new set screw hole in a clean area and try again. Or get a new pulley of proper shaft diameter. Or slot the bushing to retain use of a key?
