I have several spare Stewart 160 speedometers that look great except that the number drums for the odometer and speed, appear to be swelling and cracking similar to what pot metal does when it starts to deteriorate and swell. So much so that the numbers are pressing against the backside of the speedometer cover plate. Everything else on the speedometer, mechanically, is fine. Does anyone still manufacture replacement number drums for the various models of Stewart speedometers? If so, where could I obtain them? Jim Patrick
This is the main problem with Stewarts from what I've read and seen. To my knowledge, nobody reproduces the potmetal parts but maybe Russ Furstnow will offer some advice.
They made one with plastic numbers. They never go bad.
I hate to tell you this, but once the pot metal odometer dials swell, there is no satisfactory repair that can be accomplished. The earlier plastic odometer dials are the only dials that work in a Model 160 speedometer, and no one is reproducing any internal parts for antique speedometers today.
Sorry for the bad news, Russ Furstnow
