ENGINE RUN-IN INSTRUCTIONS (Cont)
While making the Final Run-In, the engine
should develop, within 5%, the maximum rated
brake horsepower indicated for the speed at
which it is operating. If this brake horse-
power is not developed, the cause should be
determined and corrections made.
15. When the above conditions have been met,
adjust the maximum no-load speed to conform
with that specified for the particular engine.
This speed may be either higher or lower than
the maximum speed used during the Basic Run-
In. This will ordinarily require a governor
adjustment.
16. All information required in Section "E",
Final Run-In, of the Engine Test Report (see
page 5-926.), should be determined and filled
in. After the prescribed time for the Final
Run-In has elapsed, remove the load from the
dynamometer and reduce the engine speed grad-
ually to idle speed and then stop the engine.
The Final Run-In is complete.
(f) Inspection After Final Run-In
After the Final Run-In and before the Engine
Test Report is completed, a final inspection
must be made. This inspection will provide
final assurance that the engine is in proper
working order. During this inspection the
engine is also made ready for any brief delay
in delivery or installation which may occur.
This is accomplished by rust-proofing the fuel
system. Also, a rust inhibitor should be
introduced into the cooling system.
