Comprehensive Guide to Installing Grease Fittings for Aviation Equipment

Installing Grease Fittings: A Comprehensive Guide for Aviation Professionals

At SkyGeek, we understand that proper maintenance is a critical part of aircraft ownership, which is why we've created a comprehensive guide to installing grease fittings for aviation professionals. Whether you're an owner or an aircraft technician, this step-by-step guide will walk you through every part of the process in a way that's easy to follow and understand. Proper maintenance is crucial for ensuring the longevity and optimal performance of your aviation equipment, which is why we've created this important maintenance guide.

What Are Grease Fittings?

Before we dive into the installation process, let's first define what is a grease fitting. Grease fittings, also known as Zerk fittings, grease Zerk fittings or lubrication fittings, are small, threaded components that allow grease to be injected into a bearing or other moving part of your equipment. Grease fittings are essential for equipment maintenance, as they provide an easy and efficient way to lubricate bearings and deliver precise amounts of grease to other moving parts.

If you've ever wondered, "what is a Zerk fitting," or "what is a grease Zerk," they're essentially two names for the same (important) component. Invented by Oscar Zerk in the early 20th century, these specialty fittings have become standard on all types of mechanical systems, including a variety of common aviation systems. They're primarily used for directing lubrication exactly where it's needed without having to disassemble or reassemble complex systems.

Tools You Will Need

To install a Zerk grease fitting, you will need the following tools:

• Grease gun (Like the LINCOLN® 1133 Handheld Grease Gun)
• Grease
• Rags
• Safety glasses
• Gloves
• Handheld drill
• 1/8-inch drill bit
• Tap and die set (if necessary)

Some newer systems use push-in grease fittings, which can simplify installation. These don't require threading, but they do rely on tight, clean holes to ensure proper seating. Be sure to verify that you have the correct fitting type before starting your project.

Step-by-Step Guide to Installing Grease Fittings

1.) Determine the Best Location for the Grease Fitting

Before you begin the installation process, you'll need to determine the best location for the grease Zerk fittings. This will depend on the specific equipment you're working on and the location of the bearing or other moving part that needs lubrication. If you're not sure how to install a grease fitting, consult an expert or seek guidance from the manufacturer of your equipment. Once you've identified the location where you'd like to install the grease fitting, mark it with a small dot or scratch.

2.) Drill a Hole

Using your handheld drill and an 1/8-inch drill bit, carefully drill a hole at the marked location. Make sure to drill straight and avoid damaging any other parts of the equipment. Before you begin drilling, look at the backside of the surface you're drilling into to make sure there are no wires, tubes or other obstructions.

3.) Tap the Hole

If your equipment doesn't have pre-threaded holes for Zerks fittings, you'll need to use a tap and die set to create threads in the hole you just drilled. Make sure to use the appropriate size tap for the fitting you'll be installing. Work carefully, as it's important to get the threads straight.

4.) Clean the Hole

Once the hole is drilled and tapped, use a soft rag to gently clean out any debris or metal shavings from the hole.

5.) Install the Grease Fitting

Insert the threaded grease fitting into the hole you just made and tighten it by hand until it's snug. Only tighten the fitting by hand and be careful not to over-tighten the fitting, as this could strip the threads.

6.) Lubricate the Bearing or Moving Part

Using your grease gun, apply the appropriate lubricant to the component through the newly installed grease Zerk fitting. This is how to use a grease gun to get grease exactly where it needs to go - no mess, no disassembly, just smooth operation.

If you're unsure how to grease Zerk fitting components, make sure your grease gun is primed and securely attached to the Zerk. Pump until resistance increases or you see grease escaping from the relief area. That's your cue to stop.

7.) Test the Equipment

After you've lubricated the equipment, test it to ensure that it's working properly. If everything is functioning correctly, you're good to go!

Repeat these steps for every grease point where you'd like to install or replace a fitting.

Why Regular Grease Fitting Maintenance Is Important

Like other parts of your aircraft, the grease fittings require regular maintenance. Proper maintenance of your equipment's grease Zerk fittings is essential for ensuring the longevity and optimal performance of not only the grease fitting, but your aviation equipment as a whole. Regularly lubricating bearings and other moving parts can prevent wear and tear, reduce friction, and help prevent costly repairs down the line. Simple maintenance can help keep your grease fitting working smoothly and prevent problems in the future.

A common mistake is overlooking hidden grease points tucked behind panels or in tight compartments. Skipping these areas can lead to uneven wear across components. Develop a checklist of every fitting and hit each one during scheduled maintenance - your aircraft will thank you.

Conclusion

At SkyGeek, we know that proper maintenance is essential for ensuring the longevity and optimal performance of your aviation equipment and we also know that sometimes maintaining your equipment means modifying it to work better. By following this comprehensive guide to how to install Zerk fitting hardware, you can ensure that your equipment is well-maintained, well-lubricated and always functioning properly. Remember to regularly inspect and lubricate your equipment's grease Zerk fittings to prevent wear and tear and to help reduce the risk of costly repairs.

Whether you're learning how to grease a Zerk fitting, replacing old Zerks, or installing brand-new grease Zerk fittings, this guide provides everything you need to keep things running smoothly in the hangar.
