ENGINE RUN-IN INSTRUCTIONS (Cont)
6. Engine governors in most cases must be reset
at the maximum full-load speed designated for
the run-in. If a governor is encountered
which cannot be adjusted to this speed, a
stock governor should be installed for the
run-in.
7. After checking the engine performance at idle
speed and being certain the e gine and dyna-
n
mometer are operating properly, increase the
engine speed to half speed and apply the load
indicated on the Basic Run-In Horsepower
Schedule on page 5-527.
8. The engine should be run at this speed and
load for 10 minutes to allow sufficient time
for the coolant temperature to reach the nor-
mal operating range. Record length of time,
speed, brake horsepower, coolant temperature
and lubricating oil pressure on the Engine
Test Report
9. Run the engine at each speed and rating for
the length of time indicated in the Basic
Run-In Horsepower Schedule. This is the
Basic Run-In. During this time engine per-
formance will improve as new parts begin
to "seat in". Record all of the required
data.
(c) Basic Run-In Inspection
1. While the engine is undergoing the Basic Run-
In, check each item indicated in Section "C"
of the Engine Test Report. Check for fuel
oil or water leaks in the rocker arm compart-
ment.
2. During the final portion of the Basic Run-In,
the engine should be inspected for fuel oil,
lubricating oil, and water leaks.
