12.Slide shaft assembly to right side, holding assembly in place. Slide split locking collar to the left side and tighten.

13.Slide rear conveyor drive sprocket onto shaft. Tighten the set screw of this drive sprocket until it extends into the hole of the hollow shaft. It should NOT touch the inner, solid shaft. Check to see that only the rear shaft moves when the sprocket is turned. If both shafts move, you have tightened the set screw too tight. Loosen the set screw until only the rear shaft moves when the sprocket is turning.

14.Insert adaptor bushing into remaining drive sprocket then place onto shaft. Make sure nylon spacer is in place. Tighten set screw making sure screw goes through slot in adaptor bushing and locks onto shaft.
