Cummins®

The Cummins 4948085 V-Belt is a component designed for use in commercial trucks. It serves a role in the operation of these vehicles by transferring power from the engine to various auxiliary components. Understanding its function and importance can help in maintaining the efficiency and reliability of truck operations.

Basic Concepts of V-Belts

V-belts are a type of belt drive that transmits power between two or more pulleys by means of friction. They are characterized by their trapezoidal cross-section, which allows them to fit snugly into matching grooves on the pulleys. This design enhances grip and reduces slippage, making V-belts suitable for a wide range of automotive applications, including driving alternators, water pumps, and air conditioning compressors ¹.

Purpose of the Cummins 4948085 V-Belt

This Cummins part is specifically engineered to drive multiple components within a truck’s engine system. It plays a role in powering the alternator, which charges the battery and supplies electricity to the vehicle’s electrical systems. Additionally, it drives the water pump, which circulates coolant through the engine to manage temperature. The belt also supports the air conditioning compressor, ensuring the climate control system functions correctly.

Key Features

The Cummins 4948085 V-Belt is constructed from high-quality materials that provide durability and performance. Its design includes specific dimensions and a trapezoidal cross-section to ensure a secure fit on pulleys and efficient power transmission. The belt is also engineered to withstand the rigors of commercial truck operation, including high temperatures and variable loads ².

Benefits

This part offers several advantages over other V-belts. Its robust construction contributes to improved efficiency in power transmission, reducing the likelihood of slippage and ensuring consistent performance. The belt’s durability leads to increased reliability, minimizing the need for frequent replacements. Additionally, its design enhances longevity, providing cost-effective operation over time.

Installation

Installing the Cummins 4948085 V-Belt requires careful attention to detail to ensure proper function. The process involves routing the belt around the designated pulleys, ensuring it sits correctly in the grooves. Tools such as belt tensioners may be required to achieve the correct tension, which is critical for efficient operation and to prevent premature wear ³.

Troubleshooting

Common issues with V-belts include slippage, cracking, and fraying. These problems can arise from improper tension, misalignment, or wear and tear. For this Cummins part, regular inspection for signs of wear, such as glazing or fraying, is recommended. Addressing these issues promptly can prevent more significant problems and ensure the belt continues to operate effectively.

Maintenance

To ensure the Cummins 4948085 V-Belt operates at peak performance, regular maintenance is necessary. This includes periodic inspections for wear and damage, cleaning the belt and pulleys to remove debris, and checking tension to ensure it remains within the manufacturer’s specifications. Following these practices can extend the belt’s lifespan and maintain the efficiency of the truck’s engine system.
