ENGINE AR 1855890 - Caterpillar

Install a 2D-6392 O-Ring Seal on the end of the 6V-2197 Transducer . To slide the O-ring seal onto the transducer more easily, apply clean engine oil to the O-ring seal.
Push the transducer through the 7X-1171 Transducer Adapter until the transducer contacts the outermost portion of the crankshaft counterweight.
Withdraw the transducer 1.0 mm (0.04 inch) and hand tighten the nut on the adapter sleeve in order to secure the transducer. Move the O-ring seal downward against the adapter.
Connect the 7X-1695 Cable to the transducer.Results:Continue to the next test step.Test Step 3. Connect the 7X-1695 Cable to the P400 Timing Calibration Plug Connector
If the engine's ECM is already equipped with a P400 timing calibration plug connector, connect the 7X-1695 Cable to the P400 connector.Note: If the engine's ECM is not equipped with a P400 timing calibration plug connector, you will need to install one.Results:
OK - The engine is already equipped with a P400 connector and the connection has been made. Proceed to 5.
Not OK - The engine is not equipped with a P400 connector. Proceed to Test Step 4.Test Step 4. Install the P400 Timing Calibration Plug Connector

Disconnect the ECM P2 connector. Remove the sealing plugs from P2:22 (Timing Calibration Positive) and from P2:23 (Timing Calibration Negative).Do not discard the sealing plugs. The sealing plugs may be reinstalled when the timing calibration procedure is complete.
Install the white wire of the 170-3519 Harness into P2:22 (Timing Calibration Positive).
Install the yellow wire of the 170-3519 Harness into P2:23 (Negative Timing Calibration).Note: Ensure that the wires are installed into the correct connector terminal. Engine performance will be adversely affected if the polarity of the wires is reversed.
Reconnect the P2 connector to the J2 connector. Tighten the connector to 6.0 N m (55 lb in).
Connect the 7X-1695 Cable to the 170-3519 Harness .Results:Continue to the next test step.Test Step 5. Start the Engine and Check for Diagnostic Codes
Connect Cat ET to the service tool connector.
Start the engine and run the engine at low idle until the engine is at the correct operating temperature.
Check for active diagnostic codes.The engine must not have any active diagnostic codes during the timing calibration except for a 261-13 Engine Timing Calibration required.Expected Result:There are no active diagnostic codes or there is only an active 261-13.Results:
OK - There are no active diagnostic codes or there is only an active 261-13. Proceed to Test Step 6.
Not OK - There is at least one active code that is not 261-13.Repair: Use the procedures in this manual to troubleshoot and repair any active diagnostic codes before attempting the calibration procedure.STOPTest Step 6. Calibrate the Timing
After the engine has reached the correct operating temperature, set the engine speed to 1100 50 rpm.The engine speed must be steady within this rpm range in order to successfully perform a timing calibration.
After the engine has warmed up, access the "Timing Calibration" screen on Cat ET. Access the following display screens in order:
"Service"
"Calibrations"
"Timing Calibration"
To calibrate the timing to the correct setting,
