Which sequence correctly addresses hydraulic fluid leaks in maintenance?

Which sequence correctly addresses hydraulic fluid leaks in maintenance?

• A. Identify the source; repair or replace seals/components; re-pressurize to spec; test for leaks.
• B. Re-pressurize to spec; identify the source; test for leaks; repair
• C. Test for leaks; identify the source; re-pressurize; repair
• D. Repair seals/components; re-pressurize; identify source; test for leaks

Answer: (A)

When dealing with hydraulic fluid leaks, start by finding exactly where the leak is coming from. Knowing the source is essential so you can apply the correct fix—whether that means repairing or replacing the faulty seal or component. Once the leak source is identified and repaired, bring the system back up to its specified pressure to verify that the fix holds under normal operating conditions. Only after re-pressurizing should you test to confirm that the leak is resolved and that there are no additional leaks elsewhere. This order makes sense because repairing without knowing the exact source can lead to unnecessary work or missing other leaks, and testing before repairing doesn’t actually stop the leak. Re-pressurizing before confirming the repair ensures you’re evaluating the system in its real operating state, validating the repair work.
