Hi Marv,

I would be concerned first with matching the torque and wiring specs. If there is a difference in shaft diameters, a coupling with two different ID's is one solution. Another solution is to offset the motor and connect it to the driven shaft with a timing belt and pulleys at a 1:1 ratio.

Guys,
I'm trying to help repair a router with an intermittent Y
Axis. The original stepper is a 440 oz/in with a 3/8" shaft and 6-wire
input. Oriental no longer makes that model, and suggested a PK296-03AA
as a replacement, but that motor shaft is slightly longer, and 1/2"
Dia. Any suggestions?
