I have a rockola 474-160. The problem is I can not get the selector to work along with the grip arm. The turntable works fine and the motors work. When I press the 3 numbers in, the search arm locks in place, but there is no other movement. Then the circuit cuts the machine off. I don't think the circuit breaker works or there is something shorting it out. Can you give me few suggestions?
 
There are shafts that come out of the back sides of the gripper and arm mover motors. If you can find those shafts try turning them and see if you can get them to go full throw. The Rockola jukes were lubed with a grease that becomes hard like a rock over time. My Rockola 488 was jammed because of this grease. I heated it up with a heat gun and got it moving and knew it was my problem. Had to disassemble the gripper assembly, oil with light oil, and reassemble.

Good luck.

Frozen 474

Well, I found part of the problem like you mentioned. the gear shafts and grip arm were completely frozen. I am going to take them apart and clean thoroughly. Thanks
