2. Install the Transducer Adapter
A. Remove the electrical power from the ECM.
B. Use the appropriate engine turning tool to put either the No. 1 piston or the No. 6 piston at the top center. Refer to the Systems Operation/Testing and Adjusting.
C. Refer to Table 4. After the top center position has been located, rotate the crankshaft for the number of degrees that is applicable to your engine model. Be sure to rotate the crankshaft in the direction of rotation that is specified in the Table.
D. Refer to Table 5. Locate the engines timing calibration port.
E. Remove the plug from the timing calibration port.
F. Thread the transducer adapter into the port
Transducer adapter
Result: The transducer adapter was installed.
Proceed to Test Step 3.
3. Install the Transducer
If the crankshaft is not in the correct position when the transducer is installed, the transducer will be damaged when the engine is started.
A. Apply clean engine oil to a 2D-6392 O-Ring Seal. Install the O-ring seal on the end of the 6V-2197 Transducer.
B. Push the transducer through the transducer adapter until the transducer contacts the crankshaft counterweight.
C. 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 against the adapter.
Transducer
Result: The transducer was installed.
Proceed to Test Step 4.

4. Connect the 7X-1695 Cable as
A. If the engine harness is equipped with a connector for timing calibration, connect the 7X-1695 Cable as to the connector for timing calibration and to the transducer.
B. If the engine harness is not equipped with a connector for timing calibration, or the connector is not easily accessible, a connector can be installed. The connector can be installed on either ECM connector.
C. Refer to Illustration 2 to determine the type of engine ECM. Also, determine the ECM connector that is easily accessible.
D. Refer to Table 7 to determine the proper terminal locations for the connector that is easily accessible.
E. Remove the sealing plugs from the appropriate terminals. Do not discard the sealing plugs. The sealing plugs may be reinstalled when the timing calibration is complete.
F. Install the WH(White)wire of the 170-3519 Harness into the appropriate location.
G. Install the YL(Yellow)wire of the 170-3519 Harness into the appropriate location. Disregard the pin-outs on the label of the harness.
H. Ensure that each wire is installed into the correct location. The timing calibration will not be successful if the wires are installed incorrectly.
Wiring
Result: The wiring is installed correctly.
Proceed to Test Step 5.
5. Check for Diagnostic Codes
A. Connect Caterpillar Electronic Technician (ET) to the service tool connector. Refer to Troubleshooting, "Electronic Service Tools".
B. Start the engine and run the engine until the engine is at the normal operating temperature.
C. Check for active diagnostic codes. Wait at least 30 seconds in
