Hot Test Procedure
Start engine, run at low idle, and ensure minimum oil pressure of 235 kPa (34 psi) is present within 30 sec. Walk around the engine and check for leaks. Run straight diesel with Natural Gas shut off.
Check ET for Codes.
Run Break-In 1 Speed and Load for 1 min.
Break-In load and speed 2967 Nm at 1440 rpm.
Cycle Load Between Break-In 2 Load, and Break-In 1 Load, 3 times holding at each load for 30 sec.
Break-In load and speed 5933 Nm at 1800 rpm.
Remove dyno load and go to Low Idle.

Cat ET EGR system test
Run EGR verification check in ET, and ensure it Passes. Run the EGR verification check a second time if the first one fails. If itfailsagain shut the engine offand troubleshoot EGR system.
Cat ET EGR System Test.
If Aftertreatment is not installed the Exhaust Backpressure must be within pressure tolerance of 7 3 kPa (1.0 0.4 psi) at the end of Break-In 2.

Cat ET fuel system functional test
Run Fuel System verification check in ET, and ensure it Passes.Note: Checking to see, if this is needed or not
DO NOT Lug engine until the engine has a successful EGR verification check, and Engine Backpressure is acceptable (Aftertreatment installed or backpressure verified during Break-In 2).
Set engine speed to Hi Idle speed.
Lug to engine to "Full Load speed" and allow water temps to stabilize.
EJW 85° 4°C (185° 39°F).
SCAC 46° 3°C (115° 37°F).
ATAAC Out 48° 3°C (118° 37°F).
Acquire "Full Load Data".
Take screenshot from ET for some ECM parameters.
Lug engine to "Torque Check" speed and allow engine to stabilize.
Acquire "Torque Check Data".
Take screenshot from ET for some ECM parameters.
Go to "Gas Blending Speed and Load".
754 bkW at 1800 rpm.
Turn on Gas supply. Natural Gas supply pressure measured on engine should be between 100 70 kPa (15 to 10 psi).
Let engine stabilize for 1 min.
Acquire Diesel and Natural Gas fuel rates.
Take ET screenshot.
Remove engine load and stabilize at High Idle speed for 1 min.
Acquire Hi Idle Data.
Take screenshot from ET for some ECM parameters.
Set engine to Low Idle speed and stabilize for 1 min.
Acquire Low Idle Data.
Take screenshot from ET for some ECM parameters.Nominal Test Values
