REVERSE GEAR PIN 6E5-45571-01

Function and technical context

The reverse gear is the gear responsible for reversing the direction of rotation of the propeller when reverse gear is engaged in the engine transmission. This component forms part of the gearbox gear system, working in synchronization with the drive shaft to ensure that the boat can move backwards safely and with control. A worn or damaged pinion compromises the ability to maneuver in port, slows down the reverse gear response and can generate abnormal noises during gear reversal, directly affecting maneuverability and navigation safety.

When to replace this part?

Typical symptoms of pinion wear include difficulty engaging reverse, creaking or grinding noises when engaged, and progressive loss of reverse traction. Although the useful life of these gears is considerable, it is advisable to visually inspect their condition during each seasonal inspection, especially if difficulty in maneuvering or abnormal gear changes has been noticed. Preventively replacing the pinion before failure occurs avoids being left without maneuverability in critical situations and prevents secondary damage to other transmission components.
