Components of Cummins 3800969 Oil Seal Kit

Captive Washer Cap Screw (3821783)

The captive washer cap screw is a critical component in the Cummins 3800969 Oil Seal Kit. Its primary role is to secure various parts of the oil seal assembly in place. The captive washer design ensures that the washer remains attached to the screw, preventing loss during installation and maintenance. This feature enhances the reliability and ease of assembly of the oil seal kit ².

Oil Seal (3883775)

The oil seal, designated as 3883775, is the core component of the kit. It is responsible for preventing oil leakage from the engine’s rotating shafts. The oil seal creates a barrier between the moving parts and the lubricant, ensuring that oil remains contained within the engine. This component is essential for maintaining the engine’s lubrication system integrity and preventing oil contamination ³.

Carrier Gasket (4022497)

The carrier gasket, identified by the part number 4022497, plays a supportive role in the oil seal kit. It is used to provide a seal between the oil seal and the housing or other stationary components. The carrier gasket ensures that there are no gaps or leaks around the oil seal, contributing to the overall effectiveness of the sealing system. Its proper installation is crucial for the optimal performance of the oil seal kit ⁴.

Conclusion

The Cummins 3800969 Oil Seal Kit is a vital component for maintaining the efficiency and reliability of commercial truck engines and transmissions. By preventing oil leaks and ensuring proper lubrication, this part contributes to improved engine performance, extended component lifespan, and reduced maintenance costs. Regular maintenance and proper installation are essential for maximizing the benefits of this Cummins part.
