• Key functions

1.Structural Support: Reinforces the front of the engine block, stabilizing the crankshaft and timing gears under high rotational loads (critical for 3306 engines operating at 1,800–2,200 RPM).

2.Component Protection: Shields timing gears, bearings, and seals from external debris (e.g., dirt, dust, water) common in construction or mining environments, extending their service life.

3.Oil Containment: Prevents lubricating oil leakage from the front of the engine, maintaining proper oil levels and avoiding contamination of external components (e.g., belts, pulleys).

4.Auxiliary System Integration: Provides a secure mounting platform for auxiliary drives, ensuring their alignment with the crankshaft to minimize belt/pulley wear and maximize power transfer efficiency.
