Installation Guidelines
Proper installation is crucial for the effective performance of the seal. While specific procedures vary by application, general guidelines include:
- Preparation: Ensure the housing bore and shaft surface are clean, smooth, and free from burrs, nicks, or scratches. Any imperfections can compromise the seal's integrity.
- Lubrication: Lightly lubricate the seal lips and the shaft with the system's operating fluid or a compatible lubricant before installation. This reduces friction and prevents damage during assembly.
- Installation Tool: Use a proper seal installation tool or a soft-faced hammer with a flat, blunt object to press the seal squarely into its bore. Avoid using sharp tools or excessive force, which can deform or damage the seal.
- Alignment: Ensure the seal is installed squarely and to the correct depth. Misalignment can lead to premature wear and leakage.
- Inspection: After installation, visually inspect the seal for any signs of damage, crimping, or improper seating.
Note: Always refer to the specific equipment manufacturer's service manual for detailed installation instructions relevant to your application.
Function and Application
The Timken 470989 Seal is designed to create a barrier between two environments, typically to prevent the escape of fluid (like oil or grease) and the ingress of contaminants (like dirt, dust, or water). It is commonly used in rotating or reciprocating applications, such as:
- Automotive wheel hubs
- Industrial gearboxes
- Agricultural machinery
- Various other mechanical systems requiring fluid retention and contaminant exclusion.
Maintenance
Seals are wear components and require periodic inspection and replacement. Key maintenance considerations include:
- Regular Inspection: Periodically check for signs of leakage around the seal area. Early detection of leaks can prevent more significant damage to the system.
- Contaminant Check: Inspect for signs of external contaminants entering the system, which may indicate a compromised seal.
- Replacement Schedule: Follow the equipment manufacturer's recommended replacement intervals. Even without visible leaks, seals can harden or lose elasticity over time, reducing their effectiveness.
- Proper Lubrication: Ensure that the system maintains adequate and appropriate lubrication, as this directly impacts seal life.
Troubleshooting
If you experience issues related to the seal, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Fluid Leakage | Damaged seal during installation, worn seal, improper seal material, shaft or bore imperfections, excessive pressure/temperature. | Inspect and replace seal, ensure proper installation, check shaft/bore for damage, verify operating conditions are within seal limits. |
| Premature Seal Wear | Lack of lubrication, abrasive contaminants, excessive shaft runout, improper seal material for application, high operating temperature. | Verify lubrication, check for contaminant ingress, inspect shaft and bearings, ensure correct seal specification, manage operating temperature. |
| Seal Extrusion | Excessive pressure, incorrect gland design, too large a clearance gap. | Reduce pressure, redesign gland, reduce clearance gap, consider a harder seal material. |
