Monitoring the Engine Speed
Monitoring the Engine Speed - Gen 5 DD15 - Ops - #7628
During operation of the vehicle, the operator should limit the engine speed to 1900 rpm or less. No extra engine power is achieved at engine speeds above 1900 rpm. Shifting gears without pressing the clutch, or using the engine brakes to reduce engine speed, may result in serious powertrain damage due to higher engine speeds. Never exceed 2000 rpm; higher engine speeds may result in extensive engine damage.
Notice: Any engine overspeed
(engine speed exceeds 2500 rpm) while the vehicle is moving (vehicle
speed over 0 MPH) is considered to be an operator-induced engine overspeed.
Any mechanical engine failure within 2000 miles (3218 km) of an operator-induced
engine overspeed event will not be eligible for warranty coverage.
