The temperature portion of my dual gauge in my '67 MGBGT is failing. It shows some movement but does not indicate anywhere near the correct temperature. I'm told that there are businesses that can repair these direct acting gauges. Does anyone know of such a service? Thanks.

I've had nothing but good experiences with Nisonger. www.nisonger.com I've never had them do an oil/temp gauge, but they did a great job with my speedo and tach.

Aloha,
From your description of the temperature gauge declining performance and lower than normal readings, I would guess there is a small crack in the capillary tube. This is a direct reading gauge and is basically a thermometer. I believe it works with alcohol (maybe mercury) and a lose this will reduce the range of the readings. Over time the metal of the tube becomes brittle and fragile.
Kim is correct about Nisonger, I've used them and they do good work. Palo Alto Speedometer is another shop that repairs Smith's gauges, however I have not had an opportunity to need their service. Tony at the Autoist may have an operable used gauge, but he is probably busy ducking Ivan right now.
Safety Fast,
Dave
