That was probably me that mentioned it earlier...the cheezy movement in my Explorer II. The rotor was barely working and the movement stopped at the 20 second mark...in my attempt to greeze the rotor bearing and I killed the movement. I would suggest not monkying with it if your not experianced. If the rep is one you want to keep, seek out a member that can service that movement, it prolly just needs to be lubed and adjusted properlly, or you may end up killing it as I did.
Good Luck,
Rob
