Classic Car Clock Rebuild

[@pcbcadman1]

FYI... I knew an old clock maker years ago that totally believed in using automatic transmission oil only on his clocks. He said he had tried everything during his life time and he was convinced that the transmission oil was hands down the best.

The part number for that replacement electric movement would be most helpful.

@@dailyolds1970 Thanks. got it off ebay seller clocks4cars. it's made by Instrument Services. For the original electric unit it's P/N 104 10T that you have to swap out the top to fit. For an exact quartz replacement it's P/N S-3015

But how do you adjust the time? My repaired clock gains about 45 seconds a day!

[@dailyolds1970]

Sounds like your auto adjust plate is stuck. Clock needs to be disassembled and cleaned carefully. Then, if the clock is fast, The more you adjust the time back, the more it should slow it down to accurate time keeping. That's the theory at least, but 50 year old mechanical car clocks are rarely perfect without full rebuilds. My auto advance plate in Mt cutlass is still stuck, I need to go and free it up when I get time. I'll put a video up when I do that.

what was the part number for the replacement clock

[@dailyolds1970]

I did look for one, but unfortunately there is no part number on the packaging or piece itself. I can tell you it’s a borg Warner clock replacement kit.
