Product Description

6B4-W0090-00-1S
Crank Cylinder Assy, Yamaha,
For Outboard: Yamaha 9.9, Yamaha 15


Features:

1. High-Precision Construction: The crank cylinder assembly is built to exact specifications, ensuring tight tolerances that allow the crankshaft and pistons to move freely while minimizing friction.
2. Strong Structural Design: This assembly is robust and designed to endure the high pressures and forces generated during combustion, offering stability to the engine's moving parts.
3. Oil Flow Passages: Integrated oil channels allow lubrication to circulate around the crankshaft and pistons, reducing wear and maintaining smooth operation.
4. Heat Dissipation Properties: The cylinder assembly is designed to help disperse heat generated during operation, preventing overheating and reducing thermal stress on the engine.


Functions:

1. Supports Engine Power Generation: The crank cylinder assembly houses the pistons and crankshaft, enabling the combustion process to convert fuel into mechanical energy.
2. Transmits Engine Power: By housing and aligning the crankshaft, the crank cylinder assembly allows it to rotate smoothly, transmitting power from the pistons to the drive shaft.
3. Reduces Vibration: Through its stable construction, it minimizes vibrations and absorbs some of the shocks generated during combustion, helping to prevent wear and tear on other engine parts.
4. Enables Proper Compression: The cylinder assembly ensures a tight seal around the pistons, maintaining the correct compression ratio necessary for efficient combustion.


Maintenance Tips:

1. Regular Oil Changes: Ensure timely oil changes to maintain proper lubrication, which reduces friction in the crank cylinder assembly and prevents premature wear.
2. Monitor Engine Temperature: Overheating can damage the cylinder assembly, so ensure the cooling system is functioning correctly and inspect water intakes and pumps periodically.
3. Check for Oil Leaks: Inspect the crank cylinder area for any oil leaks, as insufficient lubrication can cause severe damage to the crankshaft and pistons.
4. Rinse After Saltwater Use: After use in saltwater, rinse the engine thoroughly with fresh water to remove salt buildup, preventing corrosion in the cylinder assembly.
5. Regular Engine Inspections: Have routine inspections to check for early signs of wear, damage, or corrosion, and keep an eye on compression levels, as a drop can indicate wear in the cylinder walls.


Common Issues and Symptoms:

1. Unusual Engine Noises: Knocking, tapping, or grinding sounds from the engine can signal wear in the crank cylinder assembly or related components like the crankshaft or connecting rods.
2. Reduced Compression: A noticeable drop in compression levels indicates potential wear or damage to the cylinder walls or piston rings within the assembly.
3. Excessive Vibration or Rough Running: Increased vibration or an irregular running engine could be due to a worn or damaged crank cylinder assembly, affecting the crankshaft alignment and balance.
4. Overheating: Persistent overheating might indicate issues within the crank cylinder assembly, as heat buildup can suggest restricted oil flow or damaged components.
5. Oil Leaks or Low Oil Pressure: Leaks around the crank cylinder area or low oil pressure can be signs of internal damage, possibly from worn seals or excessive friction due to lack of lubrication.
