The 4900896 Plain Washer is a component manufactured by Cummins, a well-established name in the commercial truck industry. This washer is significant in commercial truck applications due to its role in ensuring the integrity and performance of various mechanical assemblies.

Basic Concepts of Plain Washers

Plain washers are simple yet vital components in mechanical systems. They are typically flat, annular metal rings that serve multiple functions. Primarily, plain washers distribute the load of a threaded fastener, such as a bolt or screw, over a larger area. This helps prevent damage to the surfaces being joined. Additionally, they can provide a degree of cushioning, reduce friction, and act as spacers to maintain proper alignment and clearance in assemblies ¹.

Purpose of the 4900896 Plain Washer

The 4900896 Plain Washer is specifically designed for use in commercial trucks. It plays a role in various applications where threaded fasteners are employed. This includes securing engine components, transmission parts, and chassis elements. The washer helps in distributing the load exerted by the fastener, which is crucial for maintaining the structural integrity of the assembly. It also aids in preventing galling between the fastener and the surface, which can lead to seizing and eventual failure ².

Key Features

The 4900896 Plain Washer is characterized by several key features that enhance its performance and durability. It is typically made from high-quality steel, which provides the necessary strength and resistance to wear. The dimensions of the washer are precisely engineered to ensure a proper fit with standard fasteners used in commercial trucks. Its design includes a smooth surface finish, which minimizes friction and contributes to the overall efficiency of the fastening system.

Benefits

Using the 4900896 Plain Washer offers several advantages. It improves load distribution, which helps in preventing damage to the surfaces being joined. The washer also plays a role in preventing galling, which can occur when metal surfaces rub against each other. Additionally, it enhances fastening security by providing a stable and uniform contact area for the fastener, which is particularly important in high-stress applications found in commercial trucks ³.

Installation Guidelines

Proper installation of the 4900896 Plain Washer is crucial for ensuring optimal performance and longevity. Begin by selecting the correct size washer that matches the diameter of the fastener being used. Place the washer under the head of the bolt or screw before tightening. Ensure that the washer is seated properly and is not twisted or misaligned. Tighten the fastener to the manufacturer’s specified torque settings to avoid over-tightening, which can lead to washer deformation or failure.

Troubleshooting and Maintenance

Common issues with plain washers include deformation, corrosion, and galling. To identify problems, regularly inspect washers for signs of wear or damage. Maintenance practices such as cleaning and lubricating the washers can help prolong their life. If a washer shows signs of significant wear or damage, it should be replaced to maintain the integrity of the fastening system.

Compatibility and Application

The 4900896 Plain Washer is typically used in a variety of applications within commercial truck systems. It is compatible with standard fasteners and is often found in engine components, transmission parts, and chassis elements. When selecting a washer for a specific application, it is important to consider the load requirements and environmental conditions to ensure the washer is suitable for the intended use.
