Hi Eric - to me the speedometer is fairly simple and I have restored some including a new decal for the face. However you need to know the mechanics of the speedometer to restore/repair it without damaging it.

I had a look at doing the gauges but gave that away as too hard. The problem with these are that you cannot remove the faces as they are riveted onto a sub-bracket, therefore not being able to remove the face you cannot get into the workings or replicate the face.

Now if you had stuck to the Ford you could have had the complete set along with the switch plates.

Eric,

Being a late model CMP, Common Spares were employed, (EG Chev, Ford, Dodge, Jeep, GMC, Diamond etc) and these these instruments are Stewart Warner http://stewartwarner.com/ Note Impedence and/or resisitance must be known for each circuit, and its respective detector, as they vary from each truck circuit variety, BUT can be corrected. (Bob..... I am Keeping it simple) It mentions this on the S.W. website, with respect to fuel systems.

You are fortunate as you can get replacement parts from them OR New Old Stock which share commonality with many trucks. If they have a NSN you might trace that to New Old Stock or a Surplus set.

If the mechanism is ok behind the dial you have the task of repainting (or getting a repaint) done. The dial may be available from S.W.

If the mechanism is totally destroyed then S.W. may have that too, otherwise New Old Stock parts, again, may help.

(That is the Very Short version of a rather long winded answer).

Hi,
Most of the gauges is in a good condition but I have to test it to confirm and on the back of the gauges some said GM

Hmm,

well Bob & I have had a long discussion about this, there is a machine that can do the job, But they are few and far between.

Basically the stainless (or steel) ring around the instrument is rolled on (or, in some cases squeezed on) in the manufacture. The machine that undoes this process is owned by a select few.

If you need to get an instrument apart, you MAY find an aircraft instrument repairer, or a motorcycle instrument repairer, has the tool. I would enquire first, so that the instruments do not suffer any damage by someone trying to please your request to get the items apart.

When I was in the Navy, we used to use the tool to fix aircraft instruments, but someone threw the tool away as they were not used enough... (No comment on that).

The removal tool looks a bit like an old fashioned can-opener with a peg, instead of a cutter, which you prise under the edge of the clamp and then turn the handle, the ring around the outside is relieved from the edge of the instrument. A tricky machine, I have thought about trying to make one..

If I could get my hands on one, I would be a very busy fellow, they are a godsend as far as repairs go.

I have never done this, but if you were to carefully slice the retaining ring in half, you would be able to get teh instrument apart, but then you would have an obvious cut on the ring!

I have a watch and clock repair tool for removing hands-would work I am sure for removing needles from guages - perhaps you could borrow one from a jeweller --Greg
