Perform break-in and test procedures.
Maximum horsepower rating is 400 hp at 2100 rpm. Maximum performance would
be delivered at sea level, 60 F (16 C) intake air temperature and 29.92 in. Hg (760.0
mm Hg) barometric pressure.
If deaeration is necessary because of extremely high altitude operation (above
12,000 ft [3658 m]), deaerate at 4 percent for each 1000 ft (305 m) additional altitude
and 1 percent for each 10 F air temperature rise above 60 F (16 C).
New or newly rebuilt engines during dynamometer testing are not required to
deliver more than 96 percent of maximum horsepower at power checks.
Set engine speed at 800 rpm at no load for five to ten minutes.
ABNORMALLY HIGH OIL PRESSURE MAY INDICATE BLOCKED LUBE PASSAGES
ABNORMALLY LOW PRESSURE MAY INDICATE INSUFFICIENT
SUPPLY OF LUBE OIL FROM PUMP DUE TO PUMP WEAR, EXTERNAL LEAKAGE,
OR INCREASED CLEARANCES DUE TO BEARING FAILURE.
Check oil pressure for 10 - 32 psi (69.0 - 220.8 kPa). Shut down engine if pressure not within
Check for proper water circulation, fuel, oil, and air leaks.
