2-6. FLUID LEAKAGE DEFINITION.
The following describe the different types/classes of leaks and how they affect the status of the distributor. Become
familiar with them and remember WHEN IN DOUBT, NOTIFY UNIT MAINTENANCE. 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 more frequently then as required in PMCS.
a.
Class I Leaks. Class I leaks are identified by a wetness or discoloration not great enough to form drops.
b.
Class II Leaks. Class II leaks are identified by a leakage of fluid great enough to form drops, but not enough to
cause drops to fall from the item being inspected.
c.
Class III Leaks. Class III leaks are identified by a flow of fluid great enough to form drops that fall from the item
being inspected. If a Class III leak is discovered before operating the distributor, it cannot be operated until the leak is
repaired. If the leak is discovered during operation, the mission can be completed as long as the drops do not become a
steady stream and the fluid level is between the maximum and minimum points. If a Class III leak is discovered after an
operation is complete, and the fluid level is below the minimum point, the distributor cannot be operated until the leak is
repaired.
2-7. PMCS COLUMN ENTRY EXPLANATION.
The PMCS table is arranged in columns which inform the operator when a distributor assembly or component should be
inspected/serviced, which item is being inspected/serviced, where the item is located, the procedures necessary to
complete the task, and the conditions that prevent operation of the distributor.
a.
Item No. The item number column provides a logical sequence to performing the PMCS tasks. This sequence is
arranged in a walk-around manner. The process begins at the front of the distributor and proceeds around the right side
to the back, up the left side, and onto the operator's platform. The items being inspected are visible outside, inside, or
underneath the vehicle.
b.
Interval. This column contains a dot (-) opposite the appropriate check. Thus, if a given check is performed
before operation, a dot will appear in the "B" column. If a check should be made in two or more periods, a dot will be
placed in all the appropriate columns.
c.
Item to be Inspected. This column lists the name of the assembly or component to be inspected/serviced and its
location on the distributor.
d.
Procedure. The procedure column provides the 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 this manual, it is
referenced by paragraph number rather than repeated in this column.
e.
Equipment is Not Ready/Available If. This column lists the conditions that will cause the distributor to be
inoperable. If any of these conditions exist, the distributor will not be operated until they are corrected.
