Product Description

679-45560-00-00 
Gear 1 (26T), Yamaha,
For Outboard: Yamaha 40


Features:

1. High-Precision Engineering: The forward gear is crafted with tight tolerances to ensure seamless engagement with the pinion and other gears, providing smooth operation without excessive friction or wear.

2. Durable and Robust Design: Built to handle the torque and stress of engine power, especially at high speeds, the forward gear is designed for long-lasting durability under demanding conditions.

3. Corrosion Resistance: Like other lower unit components, the forward gear is typically treated to resist corrosion from water exposure, especially in saltwater environments.

Functions:

1. Power Transmission: The forward gear transmits power from the engine to the propeller when the motor is set in forward gear, enabling the boat to move forward.

2. Torque Management: It works within the gearbox to adjust the torque and speed delivered to the propeller, optimizing performance based on engine RPM and load conditions.

3. Engagement with Clutch Dog: It engages with the clutch dog, allowing the operator to select forward, neutral, or reverse gear through the throttle control.

Maintenance Tips:

1. Regular Inspections: Inspect the forward gear regularly for signs of wear, including chipped or damaged teeth. Catching early signs of wear can prevent further damage to the gearbox.

2. Lubrication: Ensure that the lower unit's gear oil is changed regularly. Proper lubrication is crucial to minimizing friction and preventing overheating in the gear system.

3. Check for Water Intrusion: Regularly check the gear oil for signs of water intrusion, which can lead to corrosion. If water is detected, replace the oil and inspect the seals.

4. Proper Shifting: Always shift gears smoothly and avoid abrupt changes between forward, neutral, and reverse, as this can put unnecessary strain on the forward gear and other components.

5. Flush After Saltwater Use: If using the outboard in saltwater, always flush the motor with freshwater after each use to prevent salt buildup and corrosion, which can damage the gear system over time.

Common Issues and Symptoms:

1. Grinding Noise: A worn or damaged forward gear may cause a grinding or rattling noise, especially during acceleration or while under load.

2. Difficulty Shifting: If the motor is having trouble engaging into forward gear or slips out of gear, it could indicate wear on the gear teeth or the clutch dog.

3. Loss of Propulsion: In severe cases of wear, the forward gear may not transmit power effectively to the propeller, resulting in reduced or no forward propulsion.
