Engine Lubricating Primer
Cummins®

Introduction

The Cummins 4391835 Engine Lubrication Primer is designed to facilitate the lubrication process in heavy-duty truck engines. It ensures that engine components receive adequate lubrication before the engine starts, which is important for smooth operation and longevity. This primer is particularly useful in cold weather conditions where oil viscosity increases, making it harder for the oil to circulate effectively upon startup ¹.

Function and Operation

The Cummins 4391835 Engine Lubrication Primer operates by pre-lubricating the engine’s critical components. When activated, it draws oil from the sump and directs it to key areas such as the crankshaft, camshaft, and bearings. This pre-lubrication ensures that these components are coated with oil before the engine starts, reducing friction and wear during the initial moments of operation ².

Key Features

This Cummins part is characterized by its robust design and the use of high-quality materials to withstand the demanding conditions of heavy-duty truck engines. It features a durable housing, precision-machined components, and reliable seals to prevent oil leaks. Additionally, the primer may include an integrated gauge or indicator to show when the pre-lubrication process is complete, ensuring operators can start the engine with confidence.

Benefits of Using the Cummins 4391835 Engine Lubrication Primer

Utilizing this part offers several advantages. It contributes to improved engine performance by ensuring that all moving parts are properly lubricated from the start. This reduces wear and tear on engine components, leading to enhanced reliability and potentially extending the engine’s service life. Moreover, by minimizing friction during startup, the primer can help in reducing the overall stress on the engine, contributing to more efficient operation ³.

Installation Process

Installing the Cummins 4391835 Engine Lubrication Primer involves several steps. First, ensure the engine is turned off and has cooled down. Then, locate the primer’s mounting position on the engine, following the manufacturer’s guidelines. Using the appropriate tools, connect the primer to the engine’s oil system, ensuring all connections are secure and leak-free. Finally, test the primer to confirm it operates correctly before starting the engine.

Maintenance and Troubleshooting

Regular maintenance of the Cummins 4391835 Engine Lubrication Primer is important to ensure its continued reliable operation. This includes checking for any signs of leaks, ensuring all connections are tight, and verifying that the primer activates correctly. Common issues may include failure to prime, which could be due to a blockage in the oil passages or a malfunctioning switch. Troubleshooting these issues typically involves inspecting the primer and its connections, and may require cleaning or replacing components as necessary.
