The Sony 6RC-15 - the speedometer flip clock

[Mackey]

Picked up one of the SONY Digimatic 6RC-15 rolling wheel clocks. Here's the video.

Hi Mackey, thanks for this helpful video.
I just bought a 6RC-15 that is in a bad state:
- case is cracked,
- base is broken,
- time setting knob is missing.
But the clock works and the radio also! (more or less, pot-meters and switches need a clean I think).
Your video gave me a head start in opening it up, thanks!

I have a workshop manual for one of these, I must find the time to scan it, together with some more sony ones. It shows how to open it up.

I have one in pristine condition, 'only' the motor is dead

[tonyofthelord]

you can make the light shine through the indicator window. it is tricky but doable.

Has anybody actually successfully opened up one of these motors to try and get them going? I have not much to loose anyway I guess for mine has seized.

What a fantastic looking clock radio. I want one! Unfortunately they probably never made it down under.

I think I'll try to reposition the light as well. It is now completely off-center which does not look right. Need to disassemble quite a bit though to get there.

As far as I could see now the motor is a Telechron/sealed can type motor. I have successfully got some going again by heating them up with a hairdryer while trying to turn the outgoing gear. Also lubricating by repeatedly heating up and then let drag some oil in via the axle might help.

With one that I really could not get going (a Telechron S type motor) I tried everything I could to get it open, just to try out if there is a way. The red hard sealing stuff was difficult to remove. A soldering iron made it soft, so I could scrape it away. But then still I could not open the can, even after heating it in an oven.

Thanks for that insight Johan. I might try to cut two small lines in the side, right around where the cover sits, to see if I can peel back a small strip as to be able to pry out the cover, but I will try heating it first. First to find some time and make some space

Awesome clock radio. Have a black one that works great and a white one with a frozen motor. Fixed many clock radios but this one I’ve been slow and patient with. Not made for large hands that’s for sure. Finally got the motor going. I did have to scrape the glue off and open it. Heating wasn’t working. NOT FUN getting that sucker out. Next I’m gonna replace the bulb and pray I get her back together in one piece. Trying to figure out a good placement for the bulb so it lights up more real estate. Now if only I can find a red one..

Good work!

Hi guys,

just bought one of these todays and it looks like the volume knob is loose because of the missing screw / plate. Does anyone know what sort of screw it takes or where I might find one? Sample image below.

Thank you!

[Johan de Jong]

I checked mine: I think it is M1.6, total length 6 mm (head 1.5 mm + thread 4.5 mm).
Where to get? I would first try my local hardware store, and then try online. I had a quick look online and there seems to be plenty choice.

Good luck!

Thank you Johan that is very helpful! Even the service manual doesn't list the screw type Should anyone need the service manual, I uploaded it here:
