Hello everyone.
During the upcoming winter months. I would like to get my speedometer recalibrated It is off about 10 miles per hour. Is that something I can do or should I send it out?
Any contacts as to where to send to?
All info and help are greatly Appreciated.
Cheers,
Paul

Russ Furstnow is the go-to guy for speedometers. He wrote the books. If he doesn't see this and post here, you can contact him through his forum profile.

I don't believe Russ calibrates speedometers. Mine was slow, so he set it as high as he could. It's much better now.

Hi Paul,

I wholeheartedly agree with Steve; contact Russ. There is little that we mere mortals can do to fix or adjust the speedometer head itself. The rest of the system is all doable by the likes of us. The speedometer should go to a specialist. Bill

If this is the set-up on your Coupe, do you have the correct wheel gear configuration ? Can't determine from the photos but 23" wheel takes a 60 tooth road gear X a 16 tooth pinion whereas the 21" wheel takes a 58 tooth road gear with the same 16 tooth pinion - this is considering you are utilizing a Stewart 160 speedo combination. If using the Stewart 490, there are several variations of gears & drive ratios.

Well, I guess that means he calibrated it...

As little as I know, I was about to suggest what Steve T posted above.

Jerry, LOL :-)

Larry,
I have a calibration machine and calibrate every speedometer I restore, including yours. Stewart Warner noted that a speedometer was considered "accurate" if it registered 5 mph slow or 5 mph fast of the "correct" speed!!! I try to do better that that.
I hope this helps,
Russ Furstnow
