Hi Greg,
If you are not doing it as per the manual, I don't know what "stiff" means-- If the motor ARMATURE, is turning when you turn the cam, it definitely needs to be oiled as the clutch is jammed ! Ron Rich

Aha - I do believe armature is spinning entire time cam wheel is turned. (Will check later today, as jukebox repair is not on my “honey-do” list. As a matter of fact, (to quote Carl Perkins) it’s more of of a “Honey Don’t!” lol)
Will adding oil to the spots mentioned on the basic lube chart (service manual) help free up the clutch? Or do I have to dig deeper?

Hi Greg,
Probably not-- Rowe "marketing" had a "thing" about their product "never needing oil". Rowe Engineers I spoke with, were most un-happy with that situation ! To start with, just put a drop of oil on both ends of the armature shaft-- then (depending on the motor) look for the oil wicks. I strongly urge only 20 wt. ND oil be used for saturating the felt pads. Ron Rich

All micro switches on cam plates are ok. Aligned the cam wheel per service manual. Oiled relevant parts gripper/tone arm assembly. Manually turning the cam wheel shows full service of gripper arm and stylus seems to head to the right spot. Please note action in below video. (The movement stops a couple of times, as I needed a new grip to turn cam wheel with Allen wrench) vimeo.com/348232238Question: Cam wheel is very difficult to turn ... I disassembled the plates and removed the wheel itself and inspected shaft, but it doesn’t look like an “oil-able” part. Am I correct here? |

Greg,
Sounds totally "dry" Is the armature turning when you turn that cam ?? Should not be that hard to do ! Did you oil the armature bearings ?? How didja "check" MicroSwitches ? Ron Rich

Hmm - just found a loose fuse (in fuse screw-in type holder) inside of cab. See video vimeo.com/348245081This could indeed be my problem. Looking through manual to see where it goes ... if anyone recognizes it, please let me know. G |

Gary,
A "screw type holder ?? That fuse is a GMQ style--has a "special, non-tamp" holder for it --Ron Rich

Ok - I just need to find where it fell from.
I found the correct armature bearing to oil - smoothed it up immensely.
I tested the microswitches with a basic (light bulb style) continuity tested. (One lead on ground and checked each other lead while manually depressing the switch on each one. I got either a “light-on” or a “light-off” (depending on lead) for each press. )

Greg,
Checking MicroSwitches with a light may or, may not be good enough ! See our FAQs --- Ron Rich

Woohoo. Put changer back in and it’s working now. The stylus/tone arm needs a tweak (sticks in groove at beginning of 45) and amp sounds pretty bad, but I think I’m past the hurdle on my new-found beast!
Thank Rich - more question to come I’m sure!!

OK Greg
Use the service switch to stop motor with a record on the TT, Lift tone arm up and use some 20 wt. on the TT shaft. Do NOT oil the gripper, or any part of it ! Oil the TT motor --both top and bottom bearings-- oil the TT shaft, and idler wheel shaft, lightly here-- also. Ron Rich
