Grease Zirc problem

[karmakanic]

Also keep in mind the blockage could be in the passage between the zerk and the bushings. A piece of wire and some solvent will usually loosen up things enough to open up the passage.

I usually just replace the zerk, they're too cheap to mess with trying to clean and get to reseat. It bugs me to grease a bushings and see the grease squirting back out of the zerk. You can buy an assortment of the most popular sizes at most hardware stores.

Then I stick a wire up the passage while dousing it with what ever's handy that will cut grease. (choke & carb cleaner, brake cleaner, ect). After you go back togeather with it, give the pin/bushing a fair number of extra pumps from the grease gun to force any hardened grease, debris, solvent, ect out of the bushing.

I like to see the old grease just a whipping out of the space between bushing and frame, even when I'm doing a standard grease job. Looks tacky but makes me feel like I'm treating the machine right.

HTH,

re: Rowski-"pressure on the joint you're trying to grease". I have this problem with a fitting on my steering linkage. When I turn the steering wheel and move the joint to a different position, often the grease will flow.

re: Karmakanic-"the blockage could be between the zerk and the bushings" The loader arm-to-bucket pivot pins have this problem on my tractor. After removing and de-gunking the zerk with a scratch awl, I remove the pivot pin and can easily clear the blocked passage leading from the zerk to the pviot pin. You may not want to try this technique if maintaining or regaining alignment for re-insertion of the pin could be a problem.

What you may have is a drive-in type of zerk.Often the installer fails to use the proper tool which drives them at the base.
So instead they drive them in like a nail which squashes them making the the grease gun hard to get off and can also seal the hole..........Mike

It may be like Derek said, pressure on the joint. Before you replace it, try moving the joint that the zerk is in. If it happens at a pin such as on the loader or backhoe there is a good chance that pressure is the problem. I have a pin or two on my hoe that I have to move to grease. That happens when the pin in the joint is pushed up tight to where the hole for the grease goes in. If moving the joint doesn’t work then change the zerk.

I just paid $0.62 for a zerk at the local harware store. This was the smaller 1/8" size. 5/16 wrench to install.

Jerry,
Thanks. I'll try moving it first. I should have thought of that!

i have had fittings that act like that, i just remove them and repace them, usually u can just remove and put it back and it is fine. one of lifes little mysteries/w3tcompact/icons/hmm.gif

The grease zirk on the back wheel on my rotarry cutter sometimes won't take grease. I found that by rotating the wheel/ mounting pin,. it cleared it right up... must be good bushings/seales inthere...
