This part is designed to ensure proper spacing and alignment of the cam follower lever, which is essential for the smooth functioning of the engine’s valve train system.

G855 and G855 CM558

The G855 and G855 CM558 engines both utilize the Cam Follower Lever Spacer (163003) to maintain the correct clearance between the camshaft and the valve train components. This spacing is crucial for preventing excessive wear and ensuring that the valves operate with minimal friction.

GTA855 CM558 (CM2358) G101

In the GTA855 CM558 (CM2358) G101 engine, the Cam Follower Lever Spacer (163003) plays a similar role. This engine, known for its robust design and high performance, relies on this spacer to maintain the precise alignment of the cam follower lever, contributing to the engine’s overall reliability and longevity.

N14 G

The N14 G engine also incorporates the Cam Follower Lever Spacer (163003) in its design. This part is essential for ensuring that the valve train components operate within the specified tolerances, which is vital for the engine’s performance and durability.

Each of these engines benefits from the use of the Cam Follower Lever Spacer (163003) in maintaining the integrity of the valve train system, ensuring that the engine operates smoothly and efficiently.

Role of Part 163003 in Engine Systems

The Part 163003 Cam Follower Lever Spacer is an essential component in the orchestration of various engine systems, ensuring precise and efficient operation. This spacer is strategically positioned between the cam follower housing and the cam follower lever, playing a significant role in maintaining the correct spacing and alignment.

Interaction with the Block and Cylinder

The engine block houses the cylinder, where the combustion process occurs. The Cam Follower Lever Spacer ensures that the cam follower housing is correctly spaced from the cam follower lever. This precise spacing is vital for the smooth operation of the valve train, which in turn affects the combustion efficiency within the cylinder.

Coordination with Cam Follower Housing

The Cam Follower Housing encases the cam follower, protecting it and ensuring it operates within the designed parameters. The spacer ensures that the housing is not too close or too far from the cam follower lever, which could lead to premature wear or inefficient valve operation.

Relationship with the Follower

The follower rides on the camshaft, translating the camshaft’s rotational motion into linear motion to open and close the valves. The Cam Follower Lever Spacer ensures that the follower operates within the correct range of motion, optimizing valve timing and duration.

Integration with the Cam

The cam is a lobed shaft that drives the valve train. The Cam Follower Lever Spacer ensures that the cam’s lobes interact with the follower at the correct distance, which is essential for maintaining the intended valve lift and duration. This interaction directly influences the engine’s performance and efficiency.

Conclusion

In summary, the Cam Follower Lever Spacer (Part 163003) is a key component in the valve train system, ensuring that all interacting parts—block, cylinder, cam follower housing, follower, and cam—operate in harmony. This precise spacing and alignment are fundamental to the engine’s overall performance and longevity.
