Fire Extinguisher Used To Add Gear Oil To Gearboxes
Jon Arms, Brewster, Mass.: “I use a surplus fire extinguisher to add gear oil to gearboxes. I fitted it with a pressure hose and a 1/4-in. nip valve. It holds about 2 gal. of oil, added through the top nut that holds the handle and dip tube. Air is added through the snifter valve at the top beside the pressure gauge.
    “It sure makes life easier when filling transmissions or differentials. I use a round key ring on a chain to hold the handle in the flow position. I have two of them, one used for gear oil and the other for hydraulic oil. When I was 15 and worked at a gas station, they had a large floor-mounted gear oil machine. I just downsized the idea to extinguisher size. Very convenient for a small shop.”
