I pulled my speedo this morning and am planning to send it to North Hollywood Speedometer. It is off by 15 MPH at 60 MPH. First, I have to put something on the end of the cable and count revolutions over 52'-9.5" (1/100th mi). Problem is, the cable is too short to get any tape or paperclip on it for a revolution flag. What can I grab the end of the cable with.
Second Q.......the black trim that holds the glass in place is pretty beat up. What is the best way to repaint? How does it come off? Thanks, Eddy |

This may take some time but it is what I did for calibration. First paced a car with known accurate speedo at 60mph to see how mine was off. It was about 5mph slow. Pulled speedo out and using a cordless drill spun speedo up. Would only hit 45mph but gave me a reference to adjust. Seems the speedo functions by magnetic force on round dial part. If set more in then will register higher (does not take much to make up difference. ) Put together and try. This may take a few attempts, but if you have the time and like tinkering then you can save some money. When I had one of my 928 speedo's sent out for calibration it seems the cost was around $125 (it now sticks at times) hope this helps.
