Altitude Operation
Usage:
Turbocharger speed is determined by engine high idle speed, turbocharger nozzle, exhaust bypass valve regulator assembly, and the altitude at which the engine is operating. The altitude limits are stamped on the engine information plate. The regulator assembly is sealed and any changes to the regulator assembly should be made only by your Caterpillar dealer.
The engine can be operated safely at lower altitudes than specified on the engine information plate, but will not produce rated horsepower.
Always consult your Caterpillar dealer whenever changes in operating altitudes are anticipated which differ from the nameplate limits.
