2-20. LUBRICATION SYSTEM TESTS
This paragraph is a top level test for all of the lubrication systems in the vehicle. Just follow the
path, answering the questions. Additional information and notes are given on the facing page
when necessary.
The HMMWV includes a venting system that is also checked in this paragraph. The purpose of
the vent system is to allow vapor to escape to the atmosphere under normal operation, and to
prevent venting during deep water fording operations. If the vents were left open, water would
enter the engine and other systems and cause damage. The location of the vent lines is shown
below. The location of
paragraph as required.
the other parts in the lubrication system are shown in other lower level
