REVERSE GEAR PIN 697-45571-00-00

Function and technical context

The reverse gear is a critical component of the transmission system that allows reversing the direction of rotation of the propeller, essential for docking and navigation maneuvers in confined spaces. This pinion meshes directly with the engine's main gear train, transferring power from the crankshaft to the gearbox in reverse. Its correct operation is essential to guarantee the maneuverability of the vessel and safety during navigation, especially in operations that require precision and total control of direction.

When to replace this part?

The reverse gear pinion shows wear when difficulties are observed in engaging reverse gear, irregular metallic noises in the gearbox or abnormal vibrations during reverse maneuvers. It is recommended to inspect the condition of the teeth during annual seasonal maintenance and replace it preventively if accelerated wear is observed on the flanks of the teeth or chips on the edges. A deteriorated pinion not only compromises maneuverability but can cause cascading damage throughout the gear train, resulting in costly repairs; Therefore, its preventive replacement is an investment in engine safety and durability.
