Repairing the Leak

GENERAL INFORMATION
Once the leak has been pinpointed and traced back to a source, the cause of the leak must be determined in order to properly repair the leak. For example, if a gasket is replaced, but the sealing flange is bent, the new gasket will not repair the leak. The bent flange must also be repaired.

The following conditions may cause a leak. Before attempting to repair a leak, these conditions should be checked and corrected if necessary.

GASKETS
If the source of the leak is traced back to gaskets, inspect for the following conditions and correct if necessary.
- Fluid level/pressure too high
- Plugged vent or kinked hose
- Improperly tightened fasteners or dirty or damaged threads
- Warped flanges or sealing surface
- Scratches, burrs or other damage to the sealing surface
- Damaged or worn gasket
- Cracking or porosity of the component
- Improper sealant used, where applicable
- Incorrect gasket

SEALS
If the source of the leak is traced back to seals, inspect for the following conditions and correct if necessary.
- Fluid level/pressure too high
- Plugged vent or kinked hose
- Damaged seal bore
- Damaged or worn seal
- Improper installation
- Cracks in the component
- Scratched, nicked or damaged, manual or output shaft surface
- Loose or worn bearing causing excess seal wear
