  5. 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.
