Can you put too much grease in a grease fitting?

This results in accelerated wear of the elements and complete component failure. Over greasing is also to blame for seal failure and damage. Because grease guns produce up to 15,000 psi, lip seals can rupture allowing contaminates to enter the bearing housing.


How much grease should you put in a grease fitting?

Rule of Thumb #2: One Stroke per Inch of Shaft

This rule of thumb depends entirely on the grease gun. Different grease guns deliver different volumes of grease per stroke. It would probably be better to say 2 or 3 grams per inch of shaft diameter.

What happens if you over grease?

“The heat generated over time along with the oil bleed eventually will cook the grease thickener into a hard, crusty build-up that can impair proper lubrication and even block new grease from reaching the core of the bearing. This can result in accelerated wear of the rolling elements and then component failure.”


Is it possible to over grease a bearing?

Overgreasing by applying too much grease to a bearing at one time can result in a seal failure and generate heat in the bearing housing. When too much grease is pumped into a bearing cavity, it eventually will become full. If there is no relief port on the housing, the grease will blow through the seals.

How often should you add grease to ball joints?

We recommend using a grease gun and adding 3-4 pumps of grease in the ball joint and 1 pump in greaseable bushings, every 5,000 to 10,000 miles. If you drive through creaks and in mud pits, we would recommend greasing the ball joint after you are done playing in the mud and water.


Grease hammer: how to fix a grease fitting that won’t take grease anymore



Do I grease ball joints before or after install?

i ALWAYS grease a new part after install no mater what! If it comes with a grease zerk, grease it soon and grease it often. Usually the joints will come with enough grease for assembly, but not enough for long term use. This is to keep the parts from metal on metal friction, but not to spill grease out making a mess.

How much grease should be applied to a bearing?

Open angular contact thrust ball bearings for screw drives should be lubricated with a grease quantity that fills ~ 25 to 35% of the free space in the bearing. Freshly greased bearings should be operated at low speeds during the running-in period.

How do you know how much grease to put in a bearing?

To calculate grease quantity, you need the bearing's physical dimensions (primarily the outside diameter and width). Once you have these two measurements (in inches), you multiply them together and then multiply by 0.114. The resulting answer is the grease quantity in ounces.


How do you know when a bearing has enough grease?

You can manually check the Bearing Buddy to be sure it has enough grease. All you need to do is press the edge of the piston. If you can move or rock the piston it has enough grease.

How do you know when to stop greasing?

Measures to Follow
  1. Stop greasing if you note back pressure that is not normal.
  2. Check to see that the exhaust ports on a machine are free from debris, including hard crust.
  3. Slowly pump the lubricant into a machine's bearings for several seconds. Do not use a quick-lever action. Doing so can lead to damaged seals.


How do you know when to stop pumping grease?

For example, estimate the number of inches in the shaft. Multiply that number by itself to get a rough estimate of the number of shots from the grease gun. Apply the last half of these shots slowly, and at the point that you begin to experience resistance, stop pumping.


How do you get rid of excess grease?

How To Dispose Of Cooking Grease Correctly
  1. Throw it in the trash. The overarching rule of thumb when it comes to grease and oil disposal is don't pour it down a drain. ...
  2. Reuse your cooking oil and grease. ...
  3. Recycle your cooking oil. ...
  4. Use absorbent waste to soak it up. ...
  5. Compost the leftover cooking grease. ...
  6. Do not toss oils outside.


How much grease should be installed when greasing a hub?

For traditional greases (NLGI Nos. 1 and 2), pump a ring of grease into the entire circumference of the wheel hub and coat the hub cap inner wall. The housing should only be half full of grease. Too much grease causes churning and higher temperatures.

How full should the housing be for grease lubed bearing?

A common rule-of-thumb for roller bearings located in a bearing housing is to fill the bearing housing from one third to two thirds full of grease. This amount depends on speed and temperature. Note: Grease fill in a roller bearing is critical.


Can you over pack a wheel bearing with grease?

If too much grease is “packed” into the bearing and the cavity, this grease will be pushed out when the wheel spins, and could easily ruin the brake shoes. In addition, the wheel bearing could actually overheat. Repacking wheel bearings is an easy job, and should be part of the routine maintenance of the vehicle.

Does the color of bearing grease matter?

While operators tend to associate the grease they use with a color, like deep red or bright blue. As described in the video from Mobil below, the color of the grease does not change the performance characteristics and it is only the manufacturer who determines what color their grease is.

Do you fill the bearing hub with grease?

If you can rock or move the piston, the hub is properly filled. In addition to packing the bearings in the traditional manner, it's best to get as much grease as possible inside the hub cavity between the bearings and then, while the Bearing Buddy® is off, fill it with grease as well from the backside.


Which bearing should you not lubricate?

You can run bearings dry for slow moving applications such as tonearm bearings or clock bearings. However, if bearings are used without lubrication, we recommend that they are made of a corrosion resistant material such as stainless steel.

Can you use WD 40 to grease bearings?

Did you know a spray of WD-40 Specialist White Lithium Grease is a great lithium lubricant for bearings? It reduces friction on bearings and helps keep them protected from rust as well. Simply apply by spraying directly onto the area.

When lubricating a bearing you should avoid?

Mistake 2 – Over and under Lubrication

The second mistake we must avoid is adding too much, or not enough grease. Too much grease builds pressure, pushing the rolling elements through the fluid film and against the outer race.


Is wheel bearing grease OK for ball joints?

It's suitable for any object with a gliding motion, including ball joints and U-joints. Disc and drum grease is water resistant and can be used on disk and drum brakes. It can withstand extremely high temperatures generated from the high speeds of the wheel and the pressure from the brakes.

Do you grease tie rod ends before installing?

Some outer tie rods come with a grease fitting, which often come pre-greased and do not require any additional grease added when installed. However, make sure the grease fitting bolt is tightened during installation.

Can I use white lithium grease on ball joints?

This professional quality, heavy duty lubricant has a high-cling, non-drip formula so it can be used on a range of moving parts such as hinges, ball joints, motor pivot points, sliding sun roof panels and more.
