"Oil Pumper" Runs On Air Pressure

"Oil Pumper" Runs On Air Pressure FARM SHOP Tools 24-3-20 "I built this handy shop tool I call the æEasy Oil Pumper' after I had spent more than 40 minutes putting six quarts of 85-140 weight gear lube into the front differential on a Case-IH 5140 Maxxum with a 20-oz. squeeze bottle and a 12-in. piece of plastic hose. I knew there had to be an easier way," says Paul Matzner, Stickney, S. Dak. The 30-in. high tool hooks up to any air compressor with at least 30 psi and makes it easy to change oil in transmissions, gearboxes, wheel hubs, final drives, etc. You pour the oil into a 2-in. fill hole on top. The compressed air forces the oil out the bottom into a 1/2-in. hose. To discharge the oil you simply turn a valve at the end of the hose. Matzner started with a 30-in. long piece of 5 by 7 by 1/4-in. thick steel tube. He cut a hole and welded a 1/2-in. pipe coupler in the lower left side of the tube to serve as the discharge. He cut another hole and welded a 1/4-in. pipe nipple into the upper right side of the tube to serve as the air inlet. A 1/4-in. plate was welded onto the bottom of the tube and the inside of it was cleaned with solvent. A 1/4-in.-thick plate with a 2-in. pipe coupler welded into the middle of it was welded onto the top of the tube. Then a pressure regulator with gauge and quick coupler was screwed onto the 1/4-in. pipe nipple, and a 5-ft. hydraulic hose with a quarter turn valve and 6-in. nipple at one end was attached to the lower coupler. A handle on one side is used to carry the unit. "It's really handy and works especially well for refilling any heavy weight oil that doesn't flow readily through a goosenecked funnel," says Matzner. "The tank holds 3 gal. so I can pour the entire contents of a 2 1/2-gal. jug into it. I use it to transfer oil into transmissions, rear ends, mechanical front wheel drive hubs, or any gearbox with a hard-to-reach fill hole. I recently put 2 1/2 gal. of 80-90 weight gear lube into the transmission of a combine in one minute and fifteen seconds with no spills. A funnel would have taken a half hour or more. "I bought the parts and fittings to build it at a local farm supply store and the steel came from a local machine shop. My total cost to build it was about $90."
