CAUTION
If the lubricating oil pressure is not within
specifications,
shut
off
the
engine
immediately. Either excessively low or
excessively high oil pressure will cause
engine damage. Correct the problem if oil
pressure is not within specifications.
Engine oil pressure must be a minimum of 69 kPa [10
psi] at approximately 700 RPM.
Make sure the engine is at operating temperature.
Move the throttle lever to the "FULL OPEN" position.
Adjust the dynamometer load until the engine maintains
the rated RPM.
Allow the readings to stabilize. Read the horsepower.
Check all the gauges, and record the readings.
NOTE
The horsepower reading will not be accurate
if the lubricating oil temperature and fuel
temperature are not within specifications.
MIN 90C [190F]
Lubricating Oil Temperature:
MAX 42C [108F]
Fuel Temperature:
Check all gauges and record the data.
CAUTION
Do not shut off the engine immediately after it
has been loaded. It must be allowed to
sufficiently cool.
Remove the dynamometer load completely, and operate
the engine at idle speed for 3 to 5 minutes. This will
allow the turbocharger and other components to cool.
NOTE
Idle periods longer than 5 minutes are to be
avoided.
Shut off the engine after the cool-down period.
