How do you free up a stuck grease fitting?

Load up a Grease Buster with Liquid Wrench, Mineral spirits, or any penetrating oil, and tap the piston a few times. As tempting as it may be, don’t smash the thing with a hammer – the point is to use vibration to get the oil in there and slowly break up the clog, not to blast it through your bearings.

Why does grease gun get stuck on ZERK?

Grease guns get stuck on fittings due to clogged zerk fittings which don’t let the grease pass through and cause a pressure build up that prevents them from releasing. So to get it unstuck unscrews the hose or hardline from the gun which will release the pressure and allow it to come off.

Why does my grease gun get stuck in the fitting?

Why does my grease gun stop working?

The most common cause is an air lock. This can be fixed by continuously pumping to see if the air will pump out. Secondly by unscrewing the barrel one turn and continuously pumping, then tightening the barrel when the grease pumps.

How to take pressure off a grease gun?

Discussion in ‘ The Garage ‘ started by svejkovat, Aug 15, 2012 . Heads up… you need to take pressure off of the fitting by loosening/wrenching the coupler body on the gun tip. That’s the gist. Hope it helps someone. Rant follows. No need to read it…. I’m just letting off steam. Good god.

What to do when a gun gets stuck on a Zerk?

Seems it’s “common knowledge” that when a gun (any gun) gets stuck on a zerk (as happens with surprising frequency apparently) you need to loosen the coupler body with a wrench on the barrel of the gun to relieve pressure on the zerk. Only then can you remove the gun without breaking the damn fitting.

Can You Grease a shaft with a Zerk?

Pretty tight tolerance. There are zerks on the arbors and the bushing needs to be drilled beneath them to grease the shaft. I had to squeeze very very hard to get grease into the shafts. Even then almost none squeeged into view. Generally when greasing a zerk the grease has much more room to escape. Now i know. One broken zerk later.

Why does my grease gun keep leaking grease?

If the coupler is too loose it leaks grease, and if it is too tight as you know they are a bear to get off. Simply adjust it so that it clips on and releases easily.
