PRELUB PRES SENSOR 4 PSI
Cummins®

The PRELUB PRES SENSOR 4 PSI (Part #3652554PL) is a component manufactured by Cummins, a well-established name in the automotive and heavy-duty truck industry. This sensor is designed to play a role in the pre-lubrication phase of engine start-up, ensuring that the engine is adequately lubricated before operation. Its function is significant in maintaining the longevity and reliability of heavy-duty truck engines ¹.

Function and Operation

The PRELUB PRES SENSOR 4 PSI operates by monitoring oil pressure during the pre-lubrication phase of engine start-up. When the engine is turned on, this Cummins part ensures that oil pressure reaches the specified 4 PSI threshold before the engine components begin to move. This process is vital for creating a protective oil film on engine parts, reducing friction and wear during the initial moments of operation ².

Purpose in Truck Operation

The primary purpose of the PRELUB PRES SENSOR 4 PSI in truck operation is to ensure that engine components are properly lubricated before they start moving. This lubrication is crucial for protecting against wear and damage that could occur if the engine were to operate without sufficient oil pressure. By confirming that the oil pressure meets the required threshold, the sensor helps in safeguarding the engine’s integrity and performance.

Key Features

This part is characterized by several key features. It is rated to operate at a pressure of 4 PSI, making it suitable for use in Cummins engines. The sensor is designed for compatibility with Cummins engine models, ensuring seamless integration within the engine’s lubrication system. Its construction and design are tailored to withstand the demanding conditions of heavy-duty truck operations.

Benefits

The benefits of using the PRELUB PRES SENSOR 4 PSI include enhanced engine protection, improved reliability, and contribution to overall engine longevity. By ensuring that the engine is properly lubricated before operation, the sensor helps in reducing wear on engine components, leading to a more reliable and longer-lasting engine. This protection is particularly important in heavy-duty applications, where engines are subjected to high loads and stresses ³.

Installation and Integration

Installation of the PRELUB PRES SENSOR 4 PSI involves integrating it within the engine’s lubrication system. This process may include wiring the sensor to the engine’s control module and mounting it in a location where it can accurately monitor oil pressure. Careful attention to these steps ensures that the sensor functions correctly and provides reliable readings.

Maintenance and Troubleshooting

Regular maintenance of the PRELUB PRES SENSOR 4 PSI includes inspection and cleaning to ensure its accurate operation. It is also important to follow recommended replacement intervals to maintain the sensor’s effectiveness. Troubleshooting common issues, such as inaccurate readings or sensor failure, may involve checking wiring connections, ensuring proper mounting, and verifying that the sensor is compatible with the engine model.
