Step #1
Slide hub and collar onto the axle.- Install the key into the axle slot (key must be at least 1-1/4" long).
- Be sure the interlocking sides of the hub and collar are facing each other.
- Note: The hub assembly may be installed onto the axle in either direction.
-
Step #2
-
Slide the hub over the key so that the key is flush on the flat side of the hub (side with engraving) and protruding on the collar side.
-
-
Step #3:
-
Index the collar so that it will interlock onto the hub. Be sure to align the key relief in the collar with the key. - In the photo above you can also see that the key is flush with this side of the hub.

Step #4:
- Slide the collar over the hub. At this point the key must be flush or protruding from the collar.
- Slide the collar over the hub. At this point the key must be flush or protruding from the collar.
-
Step #5:
- Rotate the collar 90 degrees so that the setscrew will tighten down onto the key.
- Add a small amount of 242 Loctite (or similar threadlocker) to the setscrew threads.
- As you tighten the setscrew be sure that the collar stays straight and even on the axle and does not cock. DO NOT OVER TIGHTEN!
- Yes it has to be tight but you don't have to kill it.
-
Step #6:
- Below is a photo of an installed unit.
- The collar is positively locked onto the key with the setscrew and the hub is interlocked in the collar.
- The hub will now float and oscillate freely within the collar.
