Measurements from these indicators and gauges must
be observed closely during all phases of the engine run-in
period. Refer to page 14-6 for specifications and accept-
able readings.
To correctly evaluate the engine performance, this addi-
tional measurement must be observed during engine
run-in phases.
It is good practice to observe these measurements even
if engine performance meets specifications. If engine per-
formance does not meet specifications, these measure-
ments
can
indicate
possible
reasons
for
under-performance.
Caution: Do not crank the engine for more than 30
seconds. Excessive heat will damage the starting motor.
Crank the engine and observe the oil pressure when the
engine starts. If the engine fails to start within 30 seconds,
allow the starting motor to cool for 2 minutes before crank-
ing the engine again.
