Which is the first step in resolving a hydraulic leak?

• A. Re-pressurize to spec.
• B. Test for leaks.
• C. Identify the source of the leak.
• D. Document in logbook.

Answer: (C)

Locating the exact source of a hydraulic leak is the first step because you must know what needs repair before you can fix it. When you pinpoint whether the leak comes from a hose, a fitting, a seal, a valve, or an internal component, you can choose the correct repair approach and avoid applying the wrong fix or missing a serious issue. Once the source is known, you can safely relieve system pressure, isolate the circuit if needed, clean the area for a clear inspection, and then perform the appropriate repair. After the repair, re-pressurize and test to confirm the leak is resolved. Documenting the issue is important for records, but it doesn’t address the leak itself. Pressurizing again without knowing the source could mask the problem or cause further damage.
