[The Geezer]

I was able to get the bezel off with a small fine screwdriver. Also removed the 2 screws on the back. Then unscrewed the stem off. You can then wiggle the dial and mechanism out of the case. I took a soft artist paint brush, dipped it in alcohol and “scrubbed” the mechanism being careful not to get alcohol on the dial face (just in case it might smear or kill the printing!). Blew out any dirt or dust with an tire air compressor. I oiled all the pivot points with a very light sewing machine oil. I then put the mechanism back in the case and screwed the stem back on. The bezel was left off at this point. I checked the accuracy on a tire with known pressure. The gauge was off a bit so I popped off the pointer on the dial face after zeroing the pointer. After popping the pointer off I tested the known tire pressure again. I then put the pointer back on pointing at the known pressure. I rechecked a few more times and pressed the. Bezel back on. My Ford tire gauge now works just fine. Hope your repairs/cleaning goes well too!
