Rock-ola 454 Jukebox help
Hi
I have a problem with my 454 Jukebox After playing a 45 the gripper that chooses the record gets stuck in the record holder. I have to shake the record holder to release the gripper Can anyone help as I dont have a manual Thanks Dovers |
Dovers,
I'm not quite sure what your symptom is exactly. Is the gripper actually striking the record dividers of the magazine? Is the gripper resting against the lower stop and releasing the record? A little more detailed info might help troubleshoot your problem. Respectfully, David |

Thanks for your response After the record has been played, the gripper places the 45 back into the magazine and then does not return or play the next record So basically gets stuck with the 45 it has just played in the magazine If I shake the magazine a few times it releases and plays the next record Thanks Dovers |
An assortment of possibilities exist:
1. The gripper assembly needs to be lubricated. Although the release action is motor driven (the gripping action is spring tension), it may be binding just at the point of release where the cam switch will change the circuit from transfer to scan. 2. A faulty cam switch is either losing connection or not making connection when necessary. 3. The gripper arm is binding against the magazine, thereby shaking it will allow it to travel to full extension and release the record. I hope this helps a little. I will see if I have any manuals that give the sequence of operation that might help you solve your problem. Respectfully, David |

For some strange reason my Rockola is working fine again, but i'm sure the problem will come back. I will apply motor lubrication as I think that may have been the issue. Any more info will be appreciated Regards Dovers |

Same problem came back and now after making a selection, the selection clicks through but then nothing happens. Tried the lubrication but didnt make a difference. Maybe cam switch Do you have a manual for sequence etc Regards Dovers |
Dovers,
If the mech is resting at home position when you make the selection and nothing happens, my first thought would be the microswitch and/or spring actuator on the top back side of the selection pin assembly. A solenoid will fire at the same time the selection write-in coil is fired, thereby taking pressure off the selection pins and setting the SCAN sequence into motion. By the way, it really helps to be as specific as possible with all aspects of what is happening when a malfunction occurs. Everything observable is a clue for someone trying to troubleshoot a problem from a remote location. Case in point: I had a location that would call almost every day to complain that the jukebox only gave 3 songs for a dollar, instead of the 5 songs showing on the pricing card. I would run dollar bills through the DBV until I was blue in the face and it would give 5 credits every time. I made about seven service calls before asking the ditzy barmaid to explain exactly how they were being short-changed. As it turned out, they were getting 5 credits, but the write-in sequence was not always setting the selection pin ( dirty write-in contact ring connection). Let me know more, if possible. Respectfully, David |
Hi David
I appreciate your help The guy I purchased the RockOla off is really a Pinball expert So he has asked me to gather as much info as I can, apparently there are not too many Juke experts around Sydney Hopefully he will be visiting shortly to check out the problem The Juke is the best thing I have ever purchased!
