How do you change a grease gun cartridge?

Why does my grease gun not work? 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 much grease do you put in a grease fitting? Tips for Greasing Zerk Fittings

Use Just Enough: Don’t overfill when you grease Zerk fittings. Usually, three or four pumps of grease are enough and over-greasing a joint pushes grease out the aforementioned seals, which attracts dust, sand, and dirt.

How do you know when a grease fitting is full? If this is the case, the best tactic is to “feel” the grease into the bearing cavity until slight resistance or back pressure is felt against the trigger, or lever, signaling the bearing cavity is now full.

How do you change a grease gun cartridge? – Related Questions

Why does my grease gun get stuck on the fitting?

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.

Are there different size grease Zerks?

Grease fittings come in many different styles. There are two grease fittings that are very common. These are the 1/4″-28 thread and the 1/8″ NPT thread. However, there are other less common grease fitting threads in use.

How much pressure does a grease gun produce?

The manual lever style grease gun is the most common. A typical, off-the-shelf shop gun can produce 7,500 to 15,000 psi. This can make the gun dangerous for bearing seals if misused. They typically hold 14oz (400gm) cartridges and produce various quantities/stroke.

What is the use of lubricant like grease?

Greases are applied to mechanisms that can be lubricated only infrequently and where a lubricating oil would not stay in position. They also act as sealants to prevent ingress of water and incompressible materials. Grease-lubricated bearings have greater frictional characteristics because of their high viscosity.

How do you stop a grease gun from leaking?

New grease cartridges or tubes should be stored upright (vertically) with the plastic cap up at all times. This will help to prevent oil from leaking out of the tube. If the cartridge is left in a grease gun, the gun should be depressurized and stored in a horizontal position inside a clean, cool and dry area.

What are the different types of grease fittings?

There are three major thread types for grease fittings: metric, taper or parallel, and unified. M5, M6, M7, M8, and M10 are common metric threads. British standard pipe (BSP), pipe thread fine (PTF), and national pipe thread fine (NPTF) fittings use tapered or parallel threads.

Can you over grease a grease fitting?

While applying grease minimizes wear of parts and bearing, over-lubrication can reduce a component’s life expectancy. For instance, too much grease can increase running temperatures and lead to energy losses. That is because too much grease will cause the components to push the excess lubricant away.

Are Zerk fittings universal?

Zerk Fittings may be all the same But I have Had Many that would either NOT Go On or had a Heck of a Time Getting it Off.

How do you pump a grease gun?

1) When you screw on the barrel after loading a new tube of grease, back it off a full turn to allow a little air to seep out. This gives the air bubble above the grease a place to go. 2) If loosening the barrel doesn’t work, try using the air bleeder valve if your gun has one. Keep pumping.

Why does my grease gun leak from the bottom?

Gravity, shearing and vibration are all forces that can separate oil from a grease thickener. It happens in a machine when moving parts shear through the grease to release oil into contact points. If that low point is not a sealing surface, oil can leak away from the machine, grease tube or even a grease gun.

What color is Lucas Xtra Heavy Duty Grease?

The Lucas HD grease is green.

What is the best grease for ball joints?

You will need a high temp featured grease to work with the ball joint. It will be better to try Lucas Oil 10301 Heavy Duty grease. It is waterproof, temperature stable, and long-lasting.

Can you put too much grease in a bearing?

When it comes to regreasing bearings, more is not always the better option and actually can be a costly mistake. Too much grease volume (overgreasing) in a bearing cavity will cause the rotating bearing elements to begin churning the grease, pushing it out of the way, resulting in energy loss and rising temperatures.

How often should you grease your truck?

Ideally, most tractor trailers should be manually greased at all lube points at around 12,000–24,000 miles and more frequently on the fifth wheel.
