I have the clock out of my 3.0csi on the bench hooked up to a power supply while the car gets a major body job, (sills etc). The clock was running very slow but can anyone tell me which way to turn the adjustment screw to speed it up? I guess I can turn it one way and see what happens but that could take some time if I start off in the wrong direction. Any advice appreciated.

I would like to make a suggestion.
Have the clock made into a quartz movement. The old mechanisms and gears are from a different century and not as reliable.
I personally deleted the clock and made that space a oil p and voltmeter gauge.
I believe that N Hollywood Speedometer service can do the clock for you. They do excellent work and reasonable cost.

Thanks Steve but I am a long way from LA and the clock runs fine, just looses about an hour a day. There is an adjustment screw in the back that I wanted to know which way to rotate and possibly some idea of what the graduation marks represented. I can find nothing in the service manuals I have.

Regards

I would think turning clockwise would speed it up. Most clocks use a +\- symbol. Turning right always moves time ahead should be same on back.

Adjusting a clock clockwise is wise.

Problem is that it takes a few days between adjustments, so it never convergences.

I was thinking that pros probably attach a microphone to the clock and put the tick-tock signal into a frequency counter.
