What You Need to Know About Greasing a Semi

Whether you’re an owner-operator or own an entire fleet of semi-trucks, there are routine maintenance jobs that you can’t afford to overlook, including regular greasing. The care you take of your truck directly affects your ability to earn a living, and keeping all components of a semi properly greased is one of the basics when it comes to avoiding the need for semi-truck repair in Ocala, FL. Here’s what you need to know about keeping all components of your truck properly lubricated.

What components need frequent greasing?

There are several components of a semi that need regular attention and greasing. These include the kingpins, drag link, tie rod ends and spring pins and shackles. If you’re driving a truck with drum brakes, they’ll need to have the slack adjuster and S-cam tube greased regularly. Components like fifth-wheel pivots and plates, the clutch and transmission require greasing between specified time periods. As a general rule, have your semi manually greased at all lube points every 12,000 miles. The fifth wheel should be greased more frequently, since it’s the sole component that connects the trailer to the tractor.

What should I know about degreasing and inspecting components?

You need to lubricate in all four seasons of the year. It’s smart to schedule routine maintenance during each season, since it gives you a chance to inspect all components and ensure they’re in good condition. Be sure to degrease and inspect the fifth wheel for any damage. It’s a tough job that usually requires the help of a skilled technician in semi-truck repair in Ocala, FL, since you’ll have to degrease the fifth wheel with a degreasing compound or steam cleaning device.

Cleaning off the grease has to be done thoroughly so your technician can look for cracks, broken welds, damage or missing components to the fifth wheel. It’s also smart to remove grease buildup around the lock jaw, throat and pivot points, especially before the winter season. If you have old grease on these components during the winter, it can freeze up since it’s picked up road grime and contaminants over time. When frozen grease gets stuck inside your fifth wheel, it keeps the lock from operating properly, which can cause major problems.

What should I look for when selecting grease?

When it comes to grease, the most important thing to consider is the thickener. You should always choose thickeners that have compatible materials. Thickeners are made with calcium, polyurea, lithium and more, and sometimes the materials are not compatible with each other, making the grease pasty and difficult to apply. Select a quality grease to get the job done—it’s an inexpensive investment that can keep your vehicle from needing semi-truck repair in Ocala, FL.
