PROCEDURES
During PMCS it is necessary to run the engine to
be sure that the work has been accomplished
satisfactorily. Since the pump is directly coupled
to the engine, the pump will run when the engine
runs. Running the pump for longer than a few
seconds without water in the volute will damage
the pump. When necessary to run the pump for
longer than a few seconds, make sure that suc-
tion and discharge hoses are installed and a
source of water to be pumped is available. Start
engine, prime and operate pump to duplicate
normal operation and prevent pump from over-
heating.
NOTE
When accomplishing Organizational PMCS, in-
spect all painted surfaces. Paint must be in good
condition with no bare metal or corrosion. Bare
or corroded metal that was originally painted
must be refinished as soon as possible in accord-
ance with MI L-T-704.
When accomplishing PMCS, intervals provided
in figure 4-1, Lubrication Order, take precedence
over those in table 4-1. However, intervals pro-
vided in this table should be considered mini-
mum intervals and should not be exceeded
unless the centrifugal pump unit has been pre-
served for storage.
