Diktator Electric Motors Drive Shaft Size

The currently listed Diktator motor packages specify a 5/8-inch keyed drive shaft. Verify the exact motor product and rating/dimension information when ordering, especially if replacing an older or third-party motor.

Match bore to shaft

The drive wheel’s bore is the hole that fits onto the motor shaft. It is separate from the wheel’s outside diameter, which affects belt speed.

Do not assume every wheel sold on the site has the same bore. Select the exact bore option to match your shaft and check the keyway and fastening instructions. A 19 mm bore is not the same as a 5/8-inch bore.

Using your own motor?

Check shaft diameter, keyway, mounting and clearance together. If the size or fit is uncertain, email photos and measurements to support@diktatorgrinder.com before ordering. See How the Electric Motor Mounts to Your Grinder and Calculating Belt Speed on Your 2x72 Grinder.
