You all still thinking of the "Wood box with the needle & the bottle" ? here
Admittedly I've never tried it on chucks etc, but it's worked on everything else I've greased. here
Ussually, the coupler stays locked because the pressure is still up
on whatever you just filled. That's the beauty of the Zerk system,
more back pressure actuates the coupler lock harder.
Heat up clogged grease fittings and pins with a standard hair dryer or a heat gun on the low setting. Attach the grease gun and use it immediately; the new grease will push the now-softened older grease out of the way and unclog the fitting. more
Attach a commercial grease fitting cleaner to the clogged grease fitting or grease pin. Gently tap the grease fitting cleaner with a small hammer; this will force either oil or air into the fitting, depending on the type of grease fitting cleaner, and effectively unclog the fitting. here
Spray a petroleum-based spray lube onto a grease fitting or grease fitting pin, then wipe it off with a rag. here
Grease fittings and grease pins are essentially the same thing. They both allow a grease gun to be attached onto the top to inject grease inside. Both are found on virtually every type of mechanical equipment that requires grease lubrication inside of a sealed joint. Automotive suspension systems like ball-joints and u-joints are commonly fit with grease fittings or pins, but they are also found on trucks, hydraulic equipment and aircraft. They are often called "Zerk fittings" in honor of the inventor. Keep grease fittings and pins clean and clear of dirt, debris and hardened grease so they remain effective.
Locate the spindle assembly on the top of the mower deck. Remove the protective cover, if necessary, to access the grease fitting on the spindle, using a screwdriver or wrench, as needed.
Remove the plastic cap from the end of the grease tube and insert it onto the rubber plunger in the grease gun. Retract the T handle and pull the cartridge into the grease gun. Remove the metal pull tab from the end of the cartridge and screw the end back on the grease gun a few turns. Release the T handle from the notch and tighten the tube end completely.
Load a manual grease gun by loosening the cylinder on the pump end of the gun. Pull the T handle back and lock it in place in the notch on the gun. Unscrew the pump end of the grease gun completely and remove the old grease cartridge, if necessary.
The spindles on a riding or commercial walk-behind mower are attached to the cutting deck and work with the pulleys to turn the blades below the deck so grass can be cut. The rotating parts of the spindle must be greased periodically to maintain smooth operation, and prevent overheating and potential damage. Grease fittings are located on the spindles, and provide a point where grease can be injected into the spindle with the use of a grease gun. Mowers, such as the John Deere D100 series, require only a shot or two of grease periodically.
