During monthly hydraulic checks, which measurement indicates an external leak?

• A. 1/4 in
• B. 1/2 in
• C. 3/4 in
• D. 3/8 in

Answer: (D)

External leaks are identified by comparing the size of the escaping fluid to the system’s allowable leakage limit. If the measured leak reaches the specified threshold, it’s classified as an external leak and requires action. Here, the threshold is 3/8 inch, so a measurement of 3/8 inch signals an external leak. Smaller leaks (like 1/4 inch) may be within tolerance in some setups, while larger leaks (1/2 inch or 3/4 inch) indicate more substantial problems beyond the allowed limit.
