Water Temperature Gauge Repair

So you heat up the bulb and that pushes a column of liquid and that typically uncoils a coil, as the coil grows a thooth-ed rack moves with the coil and the dial usually has a gear meshed into the tooth-ed rack. Like rack and pinion steering on a modern car.
So I figure if the back of the gauge is opened up the workings can be viewed. By placing the bulb into boiling water the needle should move. So we'll see. Probably the needle is not engaging the drive.

Someone built the gauge, someone can fix it.

P.S. If your using Photobucket as a medium, take the http;// www that shows up by clicking the yellow and black icon, and delete that. Then just highlite, copy, and paste the 'Direct Code' from Photobucket in that space. You'll see the picture instantly.

There was an article in Skinned Knuckles (1977) about repairing Water Temp Guaages. I do not have the article. There are also repair articles on the NET (Google -Water Temp. Guage Repair)
I have 3 of the gauges like yours. One works. They are "Dry Sensor " type units. They are not installed into the water circuit. Instead they are installed on a accessory stud / nut (approximately 3 inches tall) that replaces one of the head nuts. The sensing bulb mounts into the stud/ nut. When the temp rises above normal the green spot turns red. A really neat accessory.
If you locate a repair source please post it.
 
The temp guage pictured should be installed in the top hose. You can see the 2 metal plates, which clamp the inside and outside of the hose. My friend has one just like it on his 31 Phaeton.
 
Yes. I have the temp gauge in a dual mount along with the REX-A-CO oil gauge under the instrument panel. I have not installed the the bulb into the top hose, until I find a shop to repair it. I heard of a shop in Arkansas, but for the life of me, I cannot recall the name. Hence the reason for my signature line.
 
Williamson's Instruments, Inc. www.williamson.com 479-369-2551, repaired three for me and they work great, it is a bit pricey though-$150-$200. The condition of the guage internals is important, he can inspect them and give you an estimate.They work at a much higher pressure than other guages and some are so fatigued they're not repairable. Good luck.
 
I have used Abbot Instruments in Portland Oregon to repair mechanical temp gagues with very good success. (503) 246-1287

Almost missed the replies. That's the place. Wanted to say thanks.
 
Update on Water Temperature Gauge Repair:

Following correspondence with Williamson's Instruments in Arkansas that my Boyce MotoMeter gauge could be rebuilt, I sent it to them.

After not receiving a reply to my initial status request, the second request was answered with it will be sent back "unrepaired". A third email asking about "unrepaired?" was replied with,

"We are not able to repair them at this time. Sorry."

No other explanation. :confused:

Try Abbott Instruments. I have also used them with very good success. Sometimes they are busy and it may take some time.

Thanks Chris. I might do that.

I've sent this gauge out to two gauge shops that assured me it could be repaired, only to have it returned "unrepaired". I never seem to receive a direct answer as to why.

For what I pay in cross-border shipping, I could have a cluster of gauges. :rolleyes:
 
a member in our club is having some success using new gauges from the local Fleet Farm store, $20 or so. he uses the new bulb, tube etc and 'marries' it to the original gauge. he MAY use dry ice, not sure of his method. might want to investigate that option.
