| Seal Breathers to Prevent Contamination |
|
| Breathers with threads may allow water to wick its way down the threads, contaminating the lubricant. Other forms of contamination such as rust and wear particles can also develop around the threads. Overtightening with a wrench may stop water ingression but can cause pieces of thread to spall off and fall into the lubricant. Placing a small amount of thread sealant on all breathers using pipe threads will greatly reduce this risk. Thread sealant will fill the air gaps, lubricate the threads and seal out the water.

| The hydraulic pump is generally the most expensive component on a hydraulic system. It has the highest reliability risk, the highest contaminant sensitivity risk and the ability to cause chain-reaction failures. A hydraulic pump failure can be caused by a number of factors, including poor system design, using low-quality fluids and/or poor contamination control. |

From "Integrated Reliability: Condition Monitoring and Maintenance of Equipment":
The standard definition of reliability does not say much about the effects of equipment failure on businesses and people. You know when you have an unreliable plant, part or equipment due to the fact that people are angry because it fails so often. In companies with equipment reliability problems, people are busy repairing failures over and over again. This practice never ends, and you go home each day knowing there will be more trouble the next day. |
