How do you grease hard to get fittings?

Last Updated: 10th June, 2020

Remove the existing grease fitting, screw in a length of grease hose to the fitting, and add a female grease fitting on the other end of the grease hose. Now you have an easy-to-reach grease fitting that feeds into those tight spots.

Also question is, how do you free up a stuck grease fitting?

Keep grease fittings and pins clean and clear of dirt, debris and hardened grease so they remain effective.

  1. Spray a petroleum-based spray lube onto a grease fitting or grease fitting pin, then wipe it off with a rag.
  2. Heat up clogged grease fittings and pins with a standard hair dryer or a heat gun on the low setting.

Also, how often should you grease U joints? Anytime you wheel in deep water or mud, you should grease all your u-joints and steering/suspension. If you don't wheel and don't have a lift, then they really don't need too much maintenance. I'd say check'n them or adding a pump or two every 5-6K is good advice.

Also to know is, how do you fill a grease flush fitting?

Take the flush fitting out, insert grease needle into hole and pump away, replace fitting when done. IIRC the larger needles fit the hole quite nicely.

Can you over grease AU joint?

Use a high quality, high-speed, lithium based wheel bearing grease like Mystic JT-6, and grease them often. There is no such thing as greasing a u-joint too much. If you don't like the grease getting all over the frame, make yourself a splatter shield out of sheet metal.

Type LB is an industry standard for chassis grease used on tie-rod ends, ball joints, u-joints and control-arm shafts. This type of grease is not recommended for wheel bearings; acceptable greases for axle and wheel bearings carry a type GC designation.

How do you use a grease fitting cleaning tool?

Use the Zerk Zapper to clean out the dried grease behind the zerk without removing, replacing, digging or scraping. Simply fill the cylinder with a light solvent, attach the end to the clogged grease fitting, and tap the piston head with a hammer.

What does a Zerk fitting look like?

In a nutshell, the actual Zerk fitting is a small nipple that threads into a hole. That nipple has a ball bearing in the tip that keeps grease in and keeps contaminants out, but its design allows grease guns to push fresh grease into the fitting.

Why does my grease gun get stuck on the fitting?

It gets stuck because the pin / bushing is clogged. It will continue to get stuck until you clear out the built up gunk. You can try solvent and wiggling the pin, driving it back and forth. There is also a grease gun like device that injects high pressure solvent to break up the clog.

Why is it called a Zerk fitting?

One account says he developed the first 6-cylinder engine and a crude automatic transmission in Austria before coming to the U.S. in 1907, when he changed his name to Oscar Ulysses Zerk. Zerk had the idea for a new automobile lubricating system, and established a company in Cleveland to manufacture it.
