Picked up a parts truck and found a little gem burried in the leaves on the floor board

4x4Poet · 12-03-2004, 09:24 AM

Interesting. Air Press guage, huh? That's one of my 67-72 Chevy knowledge gaps. Please, educate me on their original use.

And do you think that gauge lens will clean up well enough to use? I see the air hose fitting. Any way to easily check if the guage functions?

And was that parts truck PO into brake cooling?

TEXAS 68 · 12-03-2004, 09:33 AM

I'm not that educated on that subject either, I know they were used on the larger trucks,I'mm going to clean up this weekend.
It's amazing what some people will do with a torch and welder

bagged74 · 12-03-2004, 09:58 AM

i'm not positive, but i think they were used on trucks with air brakes.

GreyHoundSteve · 12-03-2004, 10:26 AM

So your the one who bought that truck huh? I think i hear the Miami vice theme song playing. :p

TEXAS 68 · 12-03-2004, 10:30 AM

Yeah i saw that listing on ebay. The 1st guy was one of those European scam artist who tried to buy it with a cashiers check for over the amount and wanted cash back.

ChevyDude · 12-03-2004, 11:00 AM

No...that air pressure gauge monitored the remote pressure sensors that were located inside each tire. The total amount of pressure for all tires was indicated on the needle or gauge. Any takers? LOL.

LMFAO

And I thoght only corvettes had that option :p

LT4XTREME · 12-03-2004, 11:45 AM

Yes the air gauge is for the big trucks (C50,C60,C70) with air brakes. Notice that the notch for the steering column is not cut out all the way. This can be trimed to fit. My dad has a few dump trucks he uses and a few parts trucks. One of them is a 70 C60 with air brakes and a 366 big block. It has the air gauge and a huge engine driven compressor. The gauge would be cool in a air ride C10. The compressor sits above the engine on the pass side and would not fit under the hood of a pickup but it could be moved to the side of the engine. I got a vacuum gauge out of another C60 427 truck we had to bad neither truck had a tach or speed warning. Other cool and more common dump truck paarts are radio delete plate, and cowl w/o antena hole. Some day after I get my 67 C10 swb fleetside finished I would like to build one and use that tall deck 427. Thats a cool engine that don't fit well in cars but can be fitted into a pickup.

4x4Poet · 12-03-2004, 03:26 PM

If only one could find a guage lens that combines marks for a tach and the air pressure guage. That would be the set up for a manual trans, air-bagged C10. Does anybody custom mark 67-72 lenses with such a need?

Texas 68, post more pics once you have it cleaned up.

LT4XTREME · 12-03-2004, 04:29 PM

4x4poet thats what I was thinking. A person could cut and splice the air gauge lens and a tach lens together. I've seen this done with a vacuum gauge and you could not tell. Somewhere somebody has a stack of these NOS thinking no one would want one for a pickup.

That would be great for tank pressure. You still need gauges for bag pressure though...

Longhorn Man · 12-03-2004, 11:36 PM

I found one in a junk yard here a few years ago, cleaned it up and installed a new bezel, I think I sold it for 90 bucks or so on here...no tach, just air pressure. Got it off a 70 C/50 tandem axle bobtail truck. (small gas powered semi)

Hooter · 12-04-2004, 01:23 AM

man that thing red lines really early!

BobS · 12-04-2004, 01:29 AM

What did that tach come out of originally? It looks about right for a V-6.

Hooter · 12-04-2004, 02:19 AM

they didnt have diesels, back then, I think its out of a 305 v6

Just look up model identification info [found in glove box]their were 3 diesel engine used in these trucks code D=4 cyl detroit diesel and code G=v-6 toro-flow diesel and code T=3 cyl detroit diesel.Now i am sure they were not used in the 1/2-1 tons,but in the larger trucks.The larger trucks have the same dash so my guess is a larger truck dash

Hooter · 12-04-2004, 02:21 AM

wait a second, that guage on the very left looks odd to me, that doesnt look like an ammeter?

**too much stuff** · 12-04-2004, 12:37 PM

Yes, it is out of a diesel truck. The tach is driven by a cable the hooks up just like a speedo. Also notice it only goes to 4000 rpms. The battery gauge appears normal.

**special-K** · 12-04-2004, 08:41 PM

They had dieses available in Medium Duty trucks.You`ll see mention of w/diesel in the parts book,too.

Robert1970C20rstbukt · 12-04-2004, 09:31 PM

Yep, they had diesels back then. Whether it was a diesel or not was stated in the second letter of the model number. D was a L4 diesel, T was a L3 diesel, and V was a V6 Detroit diesel. There was also the GMC V6 diesel, I've never seen one but I've heard of 'em.

Hooter · 12-04-2004, 11:40 PM

its been a couple months since i put my truck to bed, and forgot that the guage saud said "battery" and not "ammeter"

Hooter · 12-05-2004, 03:10 PM

DOH, I keep forgetting about the H/D trucks

70 shorty · 12-05-2004, 06:28 PM

I'm glad someone straigtened this one out, I was guessing it must be from a deisel, but I'm way too new at this stuff to know if there were acutally any diesels then.
