Grease fittings

[EE_Bota]

I have never understood why anyone has ever broken a grease Zerk, I have been greasing for 40+ years and never have broken one.. /when they get stuck, loosen by unscrewing the front half of the grease coupler and it will fall of of the Zerk. The coupler is a collett with fingers inside. As you tighten it the fingers compress as you loosen it they relax. I usually leave them slightly loose, put it on the zerk and tighten it a little pump in grease and then slightly loosen it for easy removal. It helps to have a rag in your left hand to tighten and loosen easier.

I took my grease gun end apart the other day to make sure there is nothing wrong with it due to my trouble greasing metric fittings. There was a metal cylinder in there with a tiny hole in it. I looked like it was designed such that grease pressure pushes on the little round piece and forces the fingers to grip. I am not sure though.

I have two grease guns...I think I will try the other one of lesser quality and see if I can modify it to work better on the metric fittings. On my Lincoln, those gripper fingers seem too long to grip the metric fittings right. If I push the Lincoln tip on hard enough to contact the tip of the zerk well, when the fingers compress, it tends to push it back off a bit, causing the leaking. Put the Lincoln on a std fitting, it grips like mad, and I also have to adjust the tip sometimes to either make it grip better or make it release easier. But for metric, full tight is not even good enough.

Well I'm only 72, but somewhere in those years I did learn that guns are adjustable. I mentioned the gun was new to provide info that I was not using a mangled up gun that the tractor had run over. As I first stated, one missing, one broke and I broke two. I do believe that they were most likely in poor to broken condition when I tried to use them. All the others worked fine except for one, (it popped right out) no problem with grease squirting or with getting the gun disconnected. This has been my first experience with metric however. Live and learn, always worth while.

Some Zerks are press fit not threaded, they sound like a great way to pop out and have trouble.
