Engine Dynamometer Test - Performance Check
Make sure the air compressor will be unloaded during the
performance check.
CAUTION
Do not crank the engine for more than 30 seconds.
Excessive heat will damage the starter motor.
Crank the engine and observe the oil pressure when the
engine starts. If the engine fails to start within 30 seconds,
allow the starter motor to cool for 2 minutes before
cranking the engine again.
CAUTION
If the lubricating oil pressure is not within
specifications, shut off the engine immediately. Low
lubricating oil pressure will cause engine damage.
Correct the problem if lubricating oil pressure is not
within specifications.
Engine lubricating oil pressure must be at least 69 kPa
[10 psi] at approximately 700 rpm.
