It serves a specific function within the truck’s mechanical system, contributing to the overall performance and longevity of the vehicle. Understanding its purpose and significance is key to appreciating its role in heavy-duty truck components.

Basic Concepts of Lockplates

A lockplate, also known as a lock washer, is a thin plate used to prevent fasteners from loosening. It operates by applying pressure to the fastener and the surface it is attached to, creating friction that resists movement. This mechanism is particularly important in environments where vibrations are common, such as in heavy-duty trucks ¹.

Purpose of the Cummins 168638 Lockplate

The Cummins 168638 Lockplate is specifically designed to secure fasteners in place, preventing them from loosening due to the vibrations experienced by heavy-duty trucks. By doing so, it plays a role in maintaining the integrity of the truck’s components, ensuring that parts remain securely fastened under various operating conditions ².

Key Features

This Cummins part is characterized by its material composition, typically made from high-strength steel, and its design elements, which include a split or bent shape that provides the necessary tension to keep fasteners in place. These features contribute to its effectiveness in heavy-duty applications, offering durability and reliability.

Benefits of Using the Cummins 168638 Lockplate

Utilizing the Cummins 168638 Lockplate offers several advantages, including enhanced safety by preventing fastener loosening, increased reliability of fastened components, and improved longevity of the truck’s mechanical systems.
