If you've ever wished there was a way to grease sealed bearings without removing them from pulley, sprocket, hub or other component, you'll want to take a close look at this nifty sealed bearing greaser made by Ed Williams, Fletcher, Okla.

"Any farmer can make it for little cost," says Williams.

The greaser consists of three parts -- an 8 mm threaded grease zerk, metric nut, and a "Luer Lock" needle holder off a livestock syringe (needles fit into the Luer Lock). The zerk is screwed into one side of the nut and the Luer Lock into the other. A 16 or 18-ga. needle is then inserted into the Luer Lock.

"To use the greaser I just stick the needle under the steel seal or through the rubber seal on the bearing," says Williams. "I've used it on combines, disks, tractors, etc. If I hear a bearing going out, I can grease it enough to keep going and get home before it's ruined. Whenever I replace a sealed bearing I always give the new one an extra shot of grease before I install it."
