PIÑON ATTACK 6F5-45551-00
Description
Function and technical context
The drive pinion is the toothed wheel responsible for transmitting the engine's power to the propeller through the reduction box gear set. Integrated into the marine gear train, this component converts the high engine revolutions into the optimal rotational speed for the propulsion of the boat. Its correct operation is essential for the ship to respond accurately in maneuvers and maintain uniform traction. Wear or breakage of the pinion causes loss of propulsion power, abnormal vibrations in the transmission and, in severe cases, it can completely render the boat's displacement capacity useless.
When to replace this part?
The drive pinion should be inspected during each gearbox inspection, especially after periods of intensive navigation or in waters with sediments and abrasive particles. Symptoms of wear include clunking or grinding noises from the transmission, excessive vibration when accelerating, difficulty engaging gears, and progressive loss of thrust. Preventive replacement of the sprocket prevents chain damage to other components of the transmission system and guarantees operational continuity during cruising, professional fishing or long voyages.
