View Full Version : TR2/3/3A Temperature Gauge for 1954 TR-2 & Hand Crank

03-15-2018, 06:35 PM
I recently purchased a 1954 TR-2, which I plan to restore. It is missing the temperature gauge and none of the Parts Houses carry them. Does anybody have a old, workable temperaturegauge they would like to part with? I certainly will pay your asking price. Looking for a crank too.

Sorry don't have a gauge for you- however one option is if you can get a broken one to use as a core and send it off to one of the gauge rebuilding services. I've used Mo-Ma several times and am happy with their work - I also watched their expert rebuild a capillary temperature gauge and can confirm they know what they are doing.

Those things are fragile enough that there are very, very few of them just laying around. There is a vendor on eBay selling an approximate reproduction; fine for a driver but not for what I would call a "restoration". Most likely, you'll need to find a broken original and have it rebuilt.

However, as a temporary substitute, almost any 2" mechanical water temperature gauge will work.

I'm actually using the temp gauge from an early TR4, which is electric rather than mechanical. It looks very nearly identical to the original, but requires some other modifications like a voltage stabilizer, correct sender and a wire to the sender.

The last NOS temp gage sold on Ebay for $325, about a year ago. I watched for 4 years and finally got a trashed gage with a face that is in good shape to transfer to my working internals...and I paid $80 for that. Of all the gages, the temp is by far the rarest currently.

I had mine restored last summer by Nisonger for around $200 as I recall. Old cores are fairly readily available if the TR2 units are the same as the TR3s and I think they are.

The guy on E bay that builds new look a like gauges do look good. At a casual glance or a fairly close look it will probable pass except for very knowledgeable people.

When I get home I can take a closeup of the face of the gauge.

One of these days I'll get around to repairing my original. In the meantime, I bought one of those replacements from ebay. It's a fairly good representation of the original. but there are some significant differences if you look closely. Also, it has it's own lighting which is different from the original. I've been using it for a few years now.

Here is the listing for the gauge on ebay...https://www.ebay.com/itm/Triumph-TR2-TR3-Temperature-Gauge-CLONE-CELSIUS-or-Fahrenheit/152947168745?hash=item239c5c95e9:g:JDEAAOSwqYBWmIG v&vxp=mtr

Thanks Art,

Will definitely contact him.

...Looking for a crank too...

Can't help you there other than to note that the cranks varied through the model changes and you, of course, want an early one. Many of the used ones on offer will be for the 3A which will not be suitable for you - the 'shoulder' that rides in the crank guide will be in the wrong spot.

I believe this is a photo of a TR3A crank...


This crank is quite different though I do not know if it is for a TR2 or TR3 or both...


Your best bet may be to get some measurements from a TR2 owner who is sure they have the right crank though you can get approximate info by measuring the distance from the crank guide to the dog bolt.

Art, I have been watching that Ebay "clone" add for many years. I am pleased to see it is actually a really well done repro. I think even an OCD Triumph guy would have to do a few takes to tell it's off.

Ebay is probably the best to watch.. Lately there were 2 early hand cranks but are sold now. You got to act fast. I recently won one for my 3A after 2 years trying to be at the right place at the right time. My 3A looks like the ones above my post. The early ones have the boss "the raised part" closer to the crank.

Of course, the problem with eBay is that so many sellers don't actually know (or pretend not to know) what cars their product actually fits. I see stuff all the time advertised for the wrong car, or an impossible range of cars. So be sure that you can identify the part you need from the photo.

Also check that the rotating sleeve is present on the handle. They sometimes come off and get lost.

PS, my favorite is still the seller who was offering brake rotors to fit "TR2-TR4". Of course, TR2 never came with disc brakes; but the seller assured me they would fit.

Have you ever done a front disk brake conversion from drums, TR-2.

No, can't say that I have done it. But I know how, and there is a lot more involved than just bolting on some rotors.

I've got a friend with a Ford 302 engine in his TR4, so I guess you could say that a V8 intake manifold fits a TR4 too.

I bolted the front guide/support for the starting handle to frame to check the fit. It seems the front cowl must provide a lot of support to guide. Without the cowl on I would not like to put too much force on the handle as the guide moves a lot. Am I missing something?
In 1968 my old TR2 had a fiberglass TR3 cowl on it and I remember the guide was always a bit flimsy.


03-18-2018, 06:22 PM
Nope, I don't think you're missing anything. The supports basically just complete triangles with the sheet metal of the front apron. Without the apron, the rods bend easily.

Kind of what I thought.

The steel apron should be more rigid than the 1960s model glass fiber pannels.
