Compatibility with Cummins Engines

The Belt Guard Bracket 3644156 is compatible with the following Cummins engines:

• QSK38 CM2150 MCRS
• QSK50 CM2150 MCRS
• QSK50 CM2350 K108

These engines can be grouped based on their series and model specifications:

• QSK38 CM2150 MCRS and QSK50 CM2150 MCRS: These engines share a common base model, CM2150, and are part of the QSK series. The primary difference between these engines is the displacement, with the QSK38 having a 38-liter displacement and the QSK50 having a 50-liter displacement. Despite these differences, the Belt Guard Bracket 3644156 is compatible with both due to their similar design and mounting configurations.

• QSK50 CM2350 K108: This engine belongs to the QSK50 series with a CM2350 model. Although it has a different model designation compared to the CM2150 engines, the Belt Guard Bracket 3644156 is still compatible due to the shared design principles and mounting requirements within the QSK50 series.

By ensuring the Belt Guard Bracket 3644156 is correctly installed, operators can maintain the integrity of the belt system, leading to improved engine performance and longevity.

Role in Engine Systems

The 3644156 Belt Guard Bracket is an integral component in the assembly and protection of various engine systems. When integrated with the Compressor Guard, this bracket ensures that the belt driving the compressor remains securely in place, minimizing the risk of belt slippage or damage. This is particularly important in high-stress environments where the compressor operates under significant load.

In the context of an Engine Package, the 3644156 Belt Guard Bracket contributes to the overall structural integrity. It supports multiple belts that drive essential components such as the alternator, water pump, and power steering pump. By maintaining proper belt alignment and tension, the bracket helps in reducing wear and tear on these components, thereby enhancing the longevity and efficiency of the engine package.

When combined with a Guard, the 3644156 Belt Guard Bracket offers additional safety by shielding moving parts from external elements and debris. This is especially beneficial in industrial or agricultural applications where the engine is exposed to harsh conditions. The guard, supported by the bracket, acts as a barrier, protecting both the belts and the surrounding components from potential damage.

Conclusion

The 3644156 Belt Guard Bracket plays a significant role in maintaining the operational integrity and safety of engine systems by ensuring belt stability, supporting engine packages, and enhancing the protective capabilities of guards. Its compatibility with various Cummins engines and its robust design make it a valuable component for heavy-duty truck applications.
