    Man! That goes back a few years. I'll see if any of

    my old friends at Cessna can pull the S-sheet for me

    on the gage cluster. I think it calls out the

    companion parts and their Cessna standard number.

    Those documents will at least speak to performance

    of the senders. I think the OilT is a custom thermistor

    and OilP is a carbon pile pressure to resistance

    transducer. They all had common Rochester source

    numbers from the automotive industry. The BIG question

    will be whether or not they're still made as automotive

    spares.



    I'll see what I can find out for you.

The S-number is probably one you read off the cluster. That

a Cessna Standards number that I can go look up and tell you

what the specs are for the instrument and probably the Rochester

number it was supplied under to Cessna. It will probably

reference the companion sensors too and those can be

researched. However . . .



Can I try to talk you out of using these parts? You're assuming

that these are good parts in spite of their pedigree. If one

of them is bad now or in the future, where will you get a

replacement? There's a host of alternative gages in the automotive

and aviation worlds that are of equal quality but modern design

and production. Check out these devices:

If you're building a 28v airplane, you can easily craft a 28v to

14v down-regulator to supply power to the modern automotive

instruments.



If you REALLY want to use the salvage parts, I'll see what

I can find out for you.

Hi Bob ,



these instruments are not old and are 2 1/4 standard dimensions ;

they are not embedded in a cluster ; look at the attachement .



so if i need to change them there will be no problem !



they are fitting the latest C172 i have seen .



if you may have information on senders it will be great ; 

if not i will try to find another solution , but for the time i 

try to save money .



thanks for your help ,



Boullu guy .

   Understand. I was not aware that Rochester was still

   building for Cessna . . . but it doesn't surprise me.

   I guess I should have picked up on the magnitude of

   the S-number you quoted. When I worked there, the

   current production products were in the 1000's range.



   I'll see what I can find out about these parts.
