Hi Carlos,
What country are you in ? I have never seen, nor herd of a "Harting" before-- that looks like a broken tone arm ? Ron Rich

I come from Spain, but jukebox cames from Geramany, the thing is the tonarm is broken, but i dont have a clue how to fix it and replace it... no much information about that model.
Thank yo RON

Hi Carlos,
You can get a service manual at jukebox-world.de although it is written in German. Other than that, I cannot be a lot of help I'm afraid!
Ron,
The Harting mechanism rights were bought up by Sound Leisure in England and their jukeboxes use basically a modernised version of the Harting - so Harting still lives on, albeit under a different name!
Norman.

Hi Norman,
I thought it looked slightly familiar-- could not place it till now-- thanks-- Carlos may find later parts are available from Sound Leisure ??

Thank you Ron, thank you Norman, really appreciate your help, this machine comes from Germany, and I,m interested on restoring it, I could add more pics if you like, of course. Mechanical parts looks like quite good to me. Its only those missed wires and tonearm broke what is worse inside it.
I got the manual in german, its a very good choice, but even pics from manual are not all so clear, even so, i will try to follow the diagram to fix the wires at least.
Also I did,not know, Sound Leisure, so I just have written them, as you two proposed in the post and lets wait to see if have replacements
I will inform about the process, thanks you very much again.

Thanks everyone. I could finally arranged the rebuild of tonearm and parts missed, everything is ready to repair and getting the new parts. Apart from that, i had to place correctly a microswitch for carrousel could stops. i found several fairules, still carry on with restoring..  |

I.m still carry on with restoring, i have found another problem with records motor. the electricity 27 v are received by motor but it doesn,t spin, it sounds "Click" but only shakes and hum. Any clue again,please?¿ ibb.co/r49VxXQ |

Hi Carlos,
Is it an AC, or DC motor-- what voltage is it supposed to get-- How are you measuring (what type meter) voltage going to it ? Ron Rich

Hi Ron, thank you for interest once again.
it goes 29 volts in two motor pins, measuring with a electronic multimeter. Supposed to get 27 volts according with electric diagram. So its fine.
It,s a AC Motor. (Monophase), the coil i think is ok as well, because of the click sound and hum.

Hi Carlos,
If you are using a digital meter, it's possible it is a false reading. Either use an Analog type meter, or connect something tho the motor source to prove it's actually getting the current to run that motor. It's either got to be the motor, or power going to it ?? Ron Rich

Hi Ron, I have checked the multimeter in several power sources and it,s fine, the measures are fine.
Motors properly getS 28,5 v ac. into it, but does not spin, just sounds click and thats all.
I opened the motor, cleaned and grease everything, checked the contacts and everything cames fine...
Could it be something about electricity phase? or i,m thinking about rotor shaft wear, because its very extrange...
I have read that kind of motors are very "easy facturing"... monophase and do not need extra coils or switch to
get started, its " squirrel cage" type.
So maybe the solution its to get a new motor.

Hi Carlos,
It would appear that we are having a small problem in translations-- just because a "multi-meter" says you have the proper VOLTAGE, does not indicate that you have enough current. You must use an Analog meter to determine this. Or, you can use another motor in the circuit-- if it runs, the problem is internal in the motor, if it does not run, the problem is usually a poor contact somewhere in the circuit. Ron Rich

Hi Ron, I apologize for my english... I Know what you want to say with the analog meter to the determine the current. that,s correct... Finally, what I have done, according with your suggestions; is to find out a "fan microwave motor spare" which is the closer one to the jukebox motor, shown as pics attached... and when is connected to the power WORKS FINE!!!!... So maybe the best solution is adapting and changing the motor. I wonder now if the microwave`S one is prepare for 220v, will it work fine with 28 volts at jukebox during long time... Could jukebox have the risk of power of overloading power? maybe need a dimmer also... ibb.co/XjT4n2Nibb.co/FJZ7kVv |

Hi Carlos,
No problem on "English" ! We will understand each other sooner, or later !
On the old motor-- have you oiled that armature, on both ends ? That's a "fly clutch" type motor,and if dry, the clutch will not either dis-engage, nor re-engage properly ! Also, if that's not the problem, you may re-wind that coil -- Ron Rich
