Engine Shaft Seals

Reliable Sealing of Rotating Engine Parts

Engine oil seals provide a good seal around rotating or moving engine parts, such as shafts and crankshafts. They prevent engine oil from leaking out and protect the engine from dirt and moisture ingress. A properly functioning oil seal is essential for a clean motorcycle and reliable lubrication.

Due to heat, wear, and age, oil seals can harden or become damaged. This often leads to oil sweat or visible leakage. Timely replacement prevents oil loss, contamination of other parts, and potential engine damage.

What to Consider When Choosing an Engine Oil Seal

The correct oil seal is crucial for a leak-free fit and long service life. Pay attention to the following points:

• Dimensions: Exact inner and outer diameter and thickness to match the engine block.
• Material: Resistant to oil, heat, and engine load.
• Seal Type: Single or double lip, depending on application and load.
• Compatibility: Specifically suitable for your motorcycle type and position in the engine block.

Careful Installation for Long-Lasting Sealing

During installation, a clean and undamaged surface is essential. Install the oil seal straight and in the correct direction to prevent premature wear. With a suitable engine oil seal, the engine block will continue to seal reliably, preventing unnecessary maintenance or repairs.
