Pulleys and taper locks, any help

[DennisCA]

I got an old AEG motor that I need a pulley for, the diameter of the shaft is about 28.3mm, such a metric shaft size does not exist I was told by the local company I bought a pulley & with a 28mm taper lock from (it did not fit) this is supposedly 1" 7/64ths in imperial. Anyone know if I can find such a taper lock bushing? Or is this something non-standard, it is a very old engine, perhaps 1960s.

I reckon that you should look at a 1 1/8 inch bush. This will be 0.015 inches larger than your 1 7/64 shaft. You could shim the difference with a shaft repair sleeve.

28 mm = 1.1023622"

28.3 mm = 1.1141732"

1 1/8" = 1.125

1 7/64" = 1.109375

I've also considered taking sandpaper to the current bushing, or to the motor shaft to get rid of those .3mm in either direction

If it's an inexpensive motor, you could try the sandpaper. If the shaft isn't heat treated it'll probably work.

Heat the pulley and try it on the shaft.
