TM 5-3895-370-14&P 5-7. FLUID LEAKAGE DEFINITION. The following paragraphs describe the different types/classes of leaks and how they affect the status of the vehicle. Class I and II leaks are considered minor leaks and operations can continue under these conditions. When operating with these types of leaks, fluid levels must be checked regularly as required in the PMCS. a. Class I Leaks. Class I leaks are identified by a wetness or discoloration not great enough to form drops. It is more of a seepage than a leak. b. Class II Leaks. Class II leaks are identified by a flow of fluid great enough to form drops but not great enough to cause the drops to fall from the leak point. c. Class III Leaks. Class III leaks are identified by a flow of fluid great enough to form drops that fall from the leak point. (1) If a Class III leak is discovered before operating the vehicle, the vehicle can be operated as long as the fluid level is between the maximum and minimum points on the dipstick or sight glass. If the fluid level is below the minimum point on the dipstick or sight glass, do not operate the vehicle until refilled. (2) If a Class III leak is discovered during operation of the vehicle, the operation can be completed as long as the leak is drops only and not a steady stream of fluid. The fluid level must also be within its operating range. If the leak is a steady stream and/or fluid level falls below minimum point on dipstick or sight glass, turn off the vehicle. (3) If a Class III leak is discovered after operation is complete and the vehicle fluid level is below minimum on dipstick or sight glass, the vehicle cannot be operated until the leak is repaired. 5-8. PMCS TABLE DESCRIPTION. The PMCS Table is arranged in columns which inform unit maintenance which item is being inspected/serviced, when a vehicle assembly or component should be inspected/serviced, where the item is located, and the procedures necessary to accomplish the task. a. Item No. The Item No. column provides a logical sequence for performing the PMCS tasks. The items being inspected can be visible, inside, or under the vehicle. b. Interval. The Interval column provides the appropriate time interval for performing each task. This column lists the time intervals within which the tasks should be performed. Intervals are broken into two groups: months of operation and hours of operation. In all cases, checks of items in the PMCS table should be performed under whichever interval occurs first. c. Item to Be Inspected. This column lists the name of the assembly or component to be inspected/serviced and its location on the vehicle. d. Procedure. The Procedure column provides instructions necessary to accomplish the inspection/service. It also lists important Warnings, Cautions, and Notes related to each task. If a task is covered elsewhere in the manual, it is referenced by paragraph number rather than being repeated in this column. 5-6
