Sometimes, the simple things end up being harder to achieve than the more complex. Case in point: Instrumentation for a '47-54 Chevy pickup. With the abundance of complete aftermarket offering available, it would be much easier to replace the stock gauges with a modern setup. But not everyone wants fancy electronic gauges, and while even nostalgia-style analog units are available, not everyone wants those, either. So, what does the simple man who wants to stick with simple, stock gauges do when his simple gauges don't all work properly, or worse, at all? Simple-call Jim Carter Classic Truck Parts.
With the exception of the fuel gauge, my '53 3100 had decent instrumentation when first purchased. When the unfortunate "nut in the intake" happened, forcing the removal of the cylinder head, the delicate capillary tube was severed from its well-aged sending unit that time had welded to the head. Fortunately, this did not cause a coolant leak, but it did disable the temp gauge, putting me in the same boat as with fuel level when it came to knowing coolant status-guessing. Being the simple man in this case, I wanted to keep the stock gauges, so the search began. Knowing that a solder repair wouldn't suffice, a complete (N.O.S. and good-used) gauge cluster was looked into-pricey and hard to find.
Next, I looked for just a replacement temp gauge, but the standby search engine and eBay didn't turn much up. Eventually, a question was posted on a reliable message board-www.stovebolt.com-and wouldn't you know it, the answer had been under my nose the entire time. Jim Carter Classic Truck Parts (the same ones advertising here in this magazine!) had what I needed, and then some.
A call was put in to Mr. Carter himself to discuss the issues at hand. On top of informing me of his company's ability to rebuild mechanical gauges to factory specs, he also clued me in to the fact that he could rebuild my non-working fuel gauge, in 12V configuration, no less. Furthermore, he offered to supply me with the correct oil pressure gauge face (the existing one was for a high-pressure 216) with a matching Ammeter face, completing the required components for the restoration. All I had to do was tackle the first "R" of the R&R...Remove the old parts and ship the broken ones to Jim.
As you may have read elsewhere in this issue, taking things apart is no problem for me-it's the part about putting them back together that used to be a hindrance. These days, that can still apply to things associated with electronics, and this was no exception. Taking the stock gauge cluster out and apart was a bit of a chore, mainly because a majority of time was spent suspended upside-down with the back of my head pressed firmly against the clutch pedal (minus the rubber pad!), but it was accomplished-carefully. Anything over 50 years of age requires care when being handled, so a lot of caution was taken when the tiny screws holding the temp gauge were undone, the nuts on the back of the electrical posts were loosened, and the bezel split from the cluster housing, among many other things. Beyond that, even more delicate handling was used when the parts were packaged up for shipping.
Within a short amount of time, a package from Independence, Missouri, arrived on my doorstep. Flashbacks from my childhood immediately rushed through my head, as I was faced with the final "R"...Replacing the parts. No problem-I could always send anything I broke back to Jim Carter for subsequent repair if need be! As it turned out, the reinstallation went easier than anticipated, including the application of the new gauge faces. In the process, I learned the importance of a "light" hand when dealing with extremely fragile items like gauge pointers, tiny soldered wire connections, and hair-thin capillary tubes!
When all was said and done, I had overcome my childhood fears. With the battery reconnected, the ignition key was turned to On and, to my initial surprise, each gauge responded with a renewed energy (literally and accurately). To fully gauge my success as it were, the engine was fired and, lo and behold, the temp gauge read just what the fresh coolant was telling it to. The one and only somewhat unfortunate part was the drop in oil pressure, which actually wasn't reduced. Rather, I had been under the impression it was higher previously due to the incorrect gauge face! I could deal with that.

 Don't you hate when this happens?...  Don't you hate when this happens? Old fittings that have been in a cylinder head for some time tend to get quite comfortable and don't take kindly to removal. This one put up a good fight until the very end. No worries, Jim Carter Classic Truck Parts was waiting for the call! |
 Prior to the capillary incident,...  Prior to the capillary incident, the gauges in the '53 worked well enough, all except the fuel gauge, which didn't work at all, but a spare gas can helped with that. As for the oil pressure gauge, it seemed to work the best-but as you will soon see, it was all a lie! |
 Since the sending unit was...  Since the sending unit was already dislodged, it was just a matter of removing the gauge cluster unit in order to get the parts ready to ship off. On the backside of the dash you'll find four nutted studs holding the cluster in place. A 3/8-inch nutdriver works well here, but have a small open-end on hand, as well. |
 Prior to undoing any of the...  Prior to undoing any of the electrical connections, disconnect the battery! It's also a good idea to mark the wires to avoid any confusion later on. Now's also a good time to address any "iffy" wiring, too. |
 After disconnecting all the...  After disconnecting all the wires, drop the cluster out from behind the dash. In order to get the individual instruments out, you'll need to separate the bezel/glass from the housing. |
 The mechanical gauges are...  The mechanical gauges are held in place with small screws, while the electric gauges have nuts that tighten down on their sending posts that go through the housing. |
 If reusing the decorative...  If reusing the decorative parts of the cluster, take care in removing and store somewhere safe until it's time to reinstall. |
 The "square" hole that the...  The "square" hole that the temp tube feeds through is just the right size for the capillary bulb to slip through; since this particular one didn't cooperate, it didn't make any difference. If you're disassembling just to restore cosmetically, be extra gentle with both mechanical sending unit lines. |
 The temp gauge and corresponding...  The temp gauge and corresponding parts were ready to ship off to Jim Carter; now all that remained was removal of the fuel gauge. |
 Because of my increasing forgetfulness,...  Because of my increasing forgetfulness, I numbered the connections on the housing, too. The broken piece of cardboard on the electrical posts actually serves as a protective barrier between the "hot" and sending sides. |
 When the truck was updated...  When the truck was updated to 12V, the Fuel gauge wasn't wired through the voltage reducer. Obviously, it didn't appreciate the extra zap it got, which rendered it useless...until now. |
 While new cosmetic components...  While new cosmetic components are available, these parts were still in really good shape. All they needed was a little extra TLC. |
 For the bezel, I simply gave...  For the bezel, I simply gave it a once-over with extra-fine steel wool followed by some Mothers chrome polish. |
 The glass was also hit with...  The glass was also hit with the steel wool, while a fresh razor blade got rid of insulator "stuff" that began protruding from behind the bezel. The gauge faceplate simply needed to be wiped down with some window cleaner. Not bad, huh? If yours are beyond repair, Jim Carter has the goods to replace. |
