Maintaining the Health of Your Undercarriage: The Importance of Properly Maintaining Pins and Bushings

Jan 31, 2024 | News

As a heavy equipment operator or owner, you understand the critical role that pins and bushings play in the performance and longevity of your undercarriage. These components are often the first to require maintenance, and neglecting them can lead to costly repairs and decreased productivity. Today, XMGT will explore the significance of maintaining pins and bushings, how they impact your undercarriage, and the importance of routine equipment cleaning and maintenance.

The Role of Pins and Bushings in Your Undercarriage

Pins and bushings from Track Chain manufacturers, are essential components that keep your undercarriage’s track chains at the appropriate length and tension. By properly maintaining these parts, you can avoid the need for frequent servicing of your track chains until the links and rollers have reached the end of their lifespan. However, several factors can influence the lifespan of pins and bushings, including the application, type of material in which the machine operates, operator behavior, maintenance practices, and the manufacturer of the undercarriage.

The Effects of Wear on Pins and Bushings

Over time, pins and bushings experience internal wear, primarily due to a lack of lubrication. This wear is not uniform, as the pin wears on the side that comes into contact with the bushing and on the mating surface of its inner diameter. As a result, worn pins and bushings cause the tracks to stretch, known as pitching, compromising the performance of the tracks and negatively impacting the overall lifespan of your undercarriage.

Understanding the Consequences of Worn Pins and Bushings

When pins and bushings wear, the most significant damage occurs at the point where their inner diameters meet, often due to insufficient lubrication. External wear, on the other hand, is typically caused by weather conditions and intense working environments. The stretching, loosening, or pitching of the undercarriage’s chains resulting from worn pins and bushings can lead to severe damage, necessitating costly repairs. However, implementing routine maintenance measures can prevent such wear and extend the lifespan of your equipment.

The Importance of Routine Equipment Cleaning and Maintenance

To avoid the need for extensive undercarriage repairs or even the replacement of multiple parts, regular cleaning and maintenance of your equipment are crucial. By inspecting the undercarriage of your machine, you can identify any signs of damage to the pins and bushings. A simple test involves attempting to twist the bushing by hand. If it twists easily, it is an indication that the bushing needs immediate replacement. Neglecting this service can result in chain breakage and further complications. It is important to refer to the owner’s manual for machine-specific instructions on inspecting the undercarriage.
