Features:
| 1. Pulley-Like Design: The drum sheave has a pulley-style design, with grooves that guide the starter rope as it winds and unwinds during the starting process. This design ensures that the rope stays in place and operates smoothly. |
| 2. Durable Construction: It is designed to handle the repeated mechanical action of the recoil system, providing durability and reliability. |
| 3. Smooth Rope Operation: The grooves in the drum sheave prevent the starter rope from tangling or misaligning, which could otherwise affect the starting process. |
| 4. Tension Management: It helps manage the tension of the starter rope, ensuring proper engagement with the engine's flywheel when the rope is pulled. |
Functions:
| 1. Recoil Rope Management: The primary function of the drum sheave is to guide and store the recoil rope. When you pull the starter handle, the rope unwinds from the drum sheave, and when the engine starts or if the pull is released, the rope rewinds back onto the sheave. |
| 2. Ensures Smooth Pull-Start Operation: By keeping the rope aligned and tensioned properly, the drum sheave helps ensure that the manual start process is smooth, reliable, and efficient. |
| 3. Prevents Tangling: The design of the sheave keeps the rope from tangling or overlapping, which could lead to wear on the rope or starter system failure. |
The size of the drum sheave varies depending on the model and engine size of the Yamaha outboard motor. However, most drum sheaves are compact and designed to fit within the recoil starter assembly. Typical dimensions might be:
| 1. Outer Diameter: Around 4 to 6 inches (10 to 15 cm) for most smaller or medium-sized outboard motors. |
| 2. Groove Width: The grooves in the sheave are typically sized to accommodate starter ropes with diameters ranging from 5/32 to 1/4 inch (4 to 6 mm). |
Maintenance Tips:
| 1. Inspect for Wear or Cracks: Regularly inspect the drum sheave for signs of wear, such as cracks, chips, or grooves that are worn down. Any damage can lead to improper rope alignment or tangling, making it difficult to start the engine. |
| 2. Keep Clean: Dirt, sand, or debris can accumulate in the grooves of the drum sheave and interfere with the smooth operation of the starter rope. After using the outboard motor, particularly in sandy or muddy conditions, ensure the drum sheave is clean and free of debris. |
| 3. Check Rope Fitment: Ensure that the starter rope fits properly in the sheave's grooves and is not fraying or becoming damaged. A worn rope can damage the sheave over time. |
| 4. Lubricate Moving Parts: Occasionally apply a light lubricant (such as silicone spray) to the drum sheave's axle or pivot points to ensure smooth rotation. Avoid over-lubricating, as excess grease can attract dirt and debris. |
| 5. Avoid Excessive Force: When pulling the starter rope, use smooth, even force. Excessive force or jerking motions can put extra strain on the drum sheave, causing wear or damage over time. |
| 6. Replace If Damaged: If you notice the drum sheave is cracked, warped, or damaged, replace it immediately to avoid rope slippage or failure of the recoil starter system. |
Common Signs of Drum Sheave Wear:
| 1. Rope Slipping or Tangling: If the starter rope doesn't retract smoothly or tangles frequently, the sheave may be worn or damaged. |
| 2. Cracks or Chips: Visible cracks or chips in the sheave can interfere with the proper functioning of the starter system, leading to unreliable engine starts. |
| 3. Difficulty Retracting Rope: If the rope doesn't retract properly or the recoil action feels rough, it could indicate the sheave is misaligned or damaged. |
| 4. Unusual Noises: Grinding or squeaking noises when pulling the starter rope may indicate that the sheave is worn or not rotating freely. |
