Quick Answer: How A Grease Gun Works

How does the plunger work on a grease gun?

The filler nipple is the injection point for grease from a filler pump. The air-release nipple allows air to escape after new grease has been added to the grease gun and pumped into the head. The spring provides the pressure onto the plunger.

Is there a grease gun that actually works?

Best Automatic Grease Gun—Lincoln Grease Gun Its continuous operation and customized grease flow thanks to its variable speed trigger make the fully automatic LINCOLN 1162 air-operated grease gun ideal for professional use. It has 6,000 PSI and comes with a 30-inch high-pressure hose and clip.

How does an air powered grease gun work?

Air-powered or pneumatic grease guns use compressed air to apply pressure to an air piston, which drives the grease piston and forces lubricant out of the coupler into a grease fitting. By depressing the gun’s trigger, a steady flow of lubricant is dispensed. Typically, pneumatic grease guns are rated up to 6,000 psi.

Why do grease guns leak?

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 is the most powerful grease gun?

Dewalt 20V Max Cordless Grease Gun The Dewalt DCGG571M1 grease gun is present in the 1st position in this article as it is the best performing option present here. With this grease gun, you get an excellent maximum pressure rating of 10000 PSI, which is much higher than other options in this article.

Do I need a grease gun?

Engine oil comes in plastic bottles and keeps your engine lubricated and cooled. Gear oil also comes in bottles, but has a much higher viscosity to protect heavy differential gears. The heavy grease that lubricates Spicer joints and axle bearings requires a special tool, a grease gun.

How do you bleed air from a grease gun?

How do you get air out of a grease gun? An airlock is a common issue found in the Grease guns, to fix this problem turn the grease gun body Anti-clockwise for three to four times and pump the grease gun continuously until the grease comes out from the valve. This will release the Air to the top of the tube pump’s head.

How do you unblock a grease gun?

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.

What country made the grease gun?

M3 submachine gun Submachine Gun, Cal. .45, M3 Type Submachine gun Place of origin United States Service history In service 1943–present.

How many cc’s are in a pump of grease gun?

Gun grease gun dispenses a theoretical 3cc per stroke. Our tests confirm the actual volume dispensed is 2.7cc/stroke. The difference has to do with the time the valves take to close. Should a specific volume be required, a person can count the number of strokes they pump.

Do all grease guns leak?

As anyone with a conventional T-handle grease gun knows, they are prone to some drips over time, particularly if stored upright in a hot area. This rubber cap goes over the bottom of your grease gun and keep those drips contained, and your shop floor clean.

How should I store my grease gun?

The best practice to maintain a clean grease gun is to hang it horizontally inside a clean, fireproof cabinet with the plunger disengaged from the tube. Grease guns should be stored horizontally to avoid two potential problems.

Is there a grease gun that doesn’t leak?

The LockNLube® grease guns are the world’s first leak-free grease guns. The LockNLube grease coupler will not leak when locked onto a grease fitting. The LockNLube® lever grease gun delivers up to 10,000 PSI and an ounce of grease in 28 strokes.

Do you need electric grease gun?

Grease guns are an essential part of any auto mechanic’s tool kit. Additionally, although “battery-powered” may lead you to think otherwise, they’re not always more powerful than manual grease guns. So if you’re looking for power, be sure to carefully compare the psi and maximum pressure capability.

Is pistol grip or lever action grease gun better?

A lever grease gun with a high output of grease per stroke, but produces lower pressure, is the best choice for applications involving large bearings that have more clearances for grease to flow. The pistol grip grease gun usually provides lower pressure (500 psi) and lower output per stroke.
