7X-1695     Cable As    
170-3519     Harness (1)    
( 1 ) This item is not required if the engine harness has a connector for timing calibration.
Install the Transducer Adapter.
Remove the electrical power from the ECM.
Use the appropriate engine turning tool to put either the No. 1 piston or the No. 6 piston at top center. Refer to the Systems Operation/Testing and Adjusting.
Refer to Table 2. 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.

Crankshaft Rotation    
Engine Model     Number of Degrees    Direction of Rotation    
C7     100     Normal Rotation    
C9     85     Normal Rotation    
C13     75     Normal Rotation    
C15     60     Opposite Normal Rotation    
Refer to Table 3. Locate the timing calibration port of the engine.

Remove the plug from the timing calibration port.
Thread the transducer adapter into the port.Continue to the next test step.
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.
Apply clean engine oil to a 2D-6392 O-Ring Seal . Install the O-ring seal on the end of the 6V-2197 Transducer .
Push the transducer through the transducer adapter until the transducer contacts 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 against the adapter.Continue to the next test step.
Connect the 7X-1695 Cable As .

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.
If the engine harness is not equipped with a connector for timing calibration, perform the following procedure:Note: Refer to Illustration 1 or 2. The 170-3519 Harness can be connected to the P1 connector or to the P2 connector. Select the connector with the easiest access.Refer to Table 4. 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.
