Servo Motor Is Faulty

I don't know what wheel I have.  How can I find out?

Ned,

If you have hubdisk-1, then I believe the wrench size is .035" with a torque of 2-3 inch pounds and a .020" gap from sensor side of module.  A piece of thin .020" cardboard makes a good temporary spacer since it's kinda hard to get inside the  encoder housing........and it won't scratch the encoder disk.   

Hope this helps,
Russell R.

The US Digital hubdisk-1 will replace a Pittman Series GM8XXX gearmotor encoder disk.  I have a Pittman GM8224 encoder disk and the .035" allen wrench fits that setscrew.  So, if you have a Pittman GM8XXX gearmotor, then this should work.  I do not know the size for any other Pittman gearmotor encoder.

My motors are GM9234E315-R3.

I have the proper Allen wrench. How is the disc attached to the hub?  I thought it might be a press fit but no. Super glue?
