Rowe R-87 Mechanism Issue (Er30)

I am seeking guidance on repairing a R-87 mechanism. When the jukebox is turned on, the mechanism will not rotate or spin and it has an Er30 code. I've followed the steps in the manual for correcting an Er30 code. I removed the sprag assembly and motor to ensure that the gears on the sprag wheel and hub were not broken or cracked, and I clean the little grime that was on the wheel. I reinstalled the sprag assembly and motor, switched the jukebox to the Service position and press the cancel button to move the mechanism basket. When I pressed the cancel button the motor made one loud click and the Er30 displayed. The mag motor and detent LED lights on the mechanism control panel stay lit as well. I also attempted adjustments to the optical switch as recommended with no success. Any assistance or advice on how to proceed to repair the mechanism is appreciated.

Hi Juan,
For one reason or another, it appears that either the basket motor itself is jammed, or the basket is--
Remove the motor assembly and check the armature --it should FREELY "pop" in and out --if stuck in, towards the gearbox, it does not have enough torque to start. Despite what you may read elsewhere, it is my opinion that the oil wick felts, should be filled with 20 wt oil. While the motor is out, spin the basket--there should be almost no friction--oil the basket bearings lightly--check for "krap" stopping the basket ! Ron Rich

Hi Rich,

When I had the sprag assembly and motor out I did check the basket based on advice I had read in a previous post that dealt with a Rowe Er30 error. The basket did spin very freely when the motor was out. I will check the armature as suggested and re-oil the motor with 20wt. I did notice that the sprag lever looked out of position. Do you have any suggestions on testing the solenoid when I remove the sprag assembly and motor?

Hi Juan,
It's a "25 VAC" coil--just find a source and connect it ! While out, make sure that something's not "worn" in that detent train--Plunger / coil center must be clean/dry--NO "lube" of any kind !! --and that the coil is correctly adjusted--also, how are the rubber grommets inside the sprag gear also must be, clean-dry ?
I don't recall, but if this model still has a switch on the sprag unit--check the switch as outlined in the posts above--

Rich,

Thanks for your suggestions and advice.
The detent train--Plunger / coil center does not look worn and it is clean/dry with no indication of any lubrication. The 4 rubber grommets in the sprag gear are also clean and dry. There is no switch on this sprag assembly. This record mechanism looks like it has been just sitting around for a while collecting dust and "drying" out. The first issue I encountered was a seized cam motor but with some patience and lubrication I was able to get the cam motor and switch to work. I've oiled the pads on the sprag motor and the armature was moving more freely. I was unable to turn the sprag spindle when I took the sprag wheel off. I'm hoping the lubrication will do the trick when I install it to test it out otherwise I will most likely need to replace the assembly and motor. Btw, I did test the mechanism control panel on another Rowe R-series jukebox and it worked fine.

Juan,
While you have the motor out, you might put a dab of oil on the large bearing that drives the sprag gear--both ends--but just a drop on the end that has the plastic gear attached, as you do not want any on that gear !

Hello Juan,

The jukebox you have can not be a R-87, it must be a R-89 to R-94 being as this range of jukeboxes were the only ones that showed error codes.

Your Central Control Computer (CCC) will be a 4-07773-01 (the revision number can be up to -11).

As Ron says I would run the Magazine motor on the bench with a 28 volt AC supply (25 VAC would do) the detent coil also works on 28 VAC.

Please let us know how you get on.

Hi Alan,

Thank you for the keen observation. The mechanism part number is 6-08700-01. The place I picked up the mechanism thought it had been pulled from a R-87. The mech part # is the same as my R-90 so it most likely was pulled from a R-89.
Now for the update on the sprag assembly and motor. Even after oiling the sprag assembly motor it still would not turn the record basket. I took the assembly off the mech again and completely disassembled the entire assembly. The gears in the gear box were completely seized up by dried grease. I cleaned off all the dried grease from the gears, lightly oiled them and ensured that they moved well when turned. I reassembled the sprag motor and connected the sprag motor and solenoid plunger to the mech to test my handy work but the sprag gear failed to turn when I placed it in Service mode and use the cancel button to rotate the sprag wheel. The plunger solenoid did work fine retracting the spring lever to allow the sprag gear to turn. I removed the collar that holds the armature in place and powered up the motor and saw that the armature spun very slowly and would not spin at all when i reattached the collar. At this point it looks like I will need to replace the sprag motor and assembly. When I track down a replacement I will give you an update and probably will be looking for guidance from you and Rich on how to place the record basket in the correct position so that the numbers line up when selected.

Hello Juan,

I misunderstood your post.

The mechanisms from the 1979 CTI-2 through to the R-94 are identical other than the Mecanism Control up to the R-88 was 4-07221-01 to 4-07221-04 and used the opto switch with the white plug.

The R-89 to R-89 used the 4-07221-05 Mechanism Control which had index & home trimmers on the top right hand side of the board the opto switch used has a red plug.

If you get stuck for a motor in the USA, I have both new and good used motors in stock.
