Rationale: This document has been revised to: (1) Update and clarify the references. (2) Clarify that the test system schematics depict pumps as the test components, although other components may be tested by locating them downstream of a test system pump. (3) Replace NAS 1638 by the more contemporary AS4059 for fluid cleanliness levels (Table I of AS4059 is the same as the NAS 1638 cleanliness levels). (4) Update Figures 1 and 2 to conform to modern hydraulic circuit symbols and to be consistent. (5) Replace the facility filter specification MIL-F-27656 by MIL-PRF-81836 specification. (6) Delete 3.7.2, referencing gravimetric analysis of samples from the pump by-pass loop, since it is out of context in this location. (7) Clarify sampling for gravimetric analysis in 10.3. (8) Editorial changes for clarity.MAP749C has been reaffirmed to comply with the SAE Five-Year Review policy.
