New 2PCS 3080759 Hexagonal Fixed Bolt Screw for Cummins Engines
Are you looking for high-quality and reliable fastening solutions for your Cummins engines? Guangzhou Pinxin Engine Co., Ltd., a leading provider of diesel engine parts, brings you the New 2PCS 3080759 Hexagonal Fixed Bolt Screw for Cummins. As a trusted supplier specializing in cylinder liners, pistons, engine blocks, crankshafts, injectors, and diesel pumps, we understand the importance of durable and precise components for optimal engine performance. This set of two hexagonal fixed bolts is designed to meet the exact specifications required for various Cummins engine models, ensuring a secure and long-lasting connection.

Product Usage and Applications
The 3080759 Hexagonal Fixed Bolt Screw plays a crucial role in securing various components within Cummins engines. These bolts are typically used in areas requiring a strong and reliable fastening, such as securing engine blocks, cylinder heads, manifolds, and other critical parts. Their hexagonal head allows for easy and efficient tightening with standard tools, ensuring proper torque and a secure fit.
Applicable Engine Models and Their Applications
This hexagonal fixed bolt is suitable for a wide range of Cummins engine models, including but not limited to:
Cummins B Series (e.g., 4BT, 6BT): Commonly used in construction equipment like small loaders, excavators, and agricultural machinery such as tractors and irrigation pumps. These engines are also found in power generation sets for smaller power requirements.
Cummins QSB Series (e.g., QSB4.5, QSB6.7): Frequently used in medium-sized construction equipment like excavators, bulldozers, and material handling equipment like forklifts. They also power mobile and stationary generators.
Cummins ISB and ISL Series: Found in medium-duty trucks, buses, and various industrial applications, including some agricultural equipment and power generation units.
Case Studies: Imagine a construction site where a Cummins 6BT engine powers an excavator. The 3080759 hexagonal bolts would be essential in holding the engine block together, ensuring the robust performance needed for demanding digging and lifting tasks. Similarly, in agricultural applications, a Cummins QSB4.5 engine in a tractor relies on such bolts to maintain the integrity of its structure while enduring heavy workloads in the field. In power generation, Cummins ISB engines used in backup generators in hospitals or data centers depend on secure fastenings to ensure reliable power supply during critical times.
Frequently Asked Questions, Troubleshooting & Maintenance
FAQs
Q: How often should I inspect the engine bolts?
A: Regular inspection is recommended, ideally during routine engine maintenance checks, which might be every 250 to 500 operating hours, or as specified in your engine's service manual.
Q: What happens if an engine bolt comes loose?
A: A loose bolt can lead to vibrations, leaks, and potential damage to the connected components. It's crucial to address any loose bolts immediately by tightening them to the manufacturer's specified torque.
Q: Can I reuse old engine bolts when reassembling an engine?
A: It is generally recommended to use new bolts, especially for critical components like cylinder heads and main bearings. Old bolts may have stretched or fatigued, which could compromise the integrity of the assembly.
Troubleshooting & Maintenance Tip
Troubleshooting: If you notice unusual engine noise or vibrations, check for any loose or missing bolts. Pay close attention to areas where components are joined together.
Maintenance: During regular maintenance, ensure all accessible engine bolts are tightened to the correct torque specifications. Refer to your Cummins engine's service manual for the precise torque values. Applying a small amount of anti-seize compound on the bolt threads during installation can also prevent corrosion and make future removal easier.
