964016 Volvo.Penta Elbow nipple

If a 261-11 or 637-11 diagnostic code is active, verify that the wiring is installed correctly to the engine speed/timing sensors.The ECM can calibrate the mechanical differences between the Top Center (TC) of the flywheel and the TC of the timing gear on the camshaft. A transducer signals the TC of the flywheel to the ECM when a notch on a counterweight passes by the transducer. The engine speed/timing sensor signals the TC of the timing gear to the ECM. Any offset between the TC of the flywheel and the TC of the timing gear is stored into the memory of the ECM.Note: A timing calibration will not increase the available engine power.Table 2 lists the special tools that are required in order to perform this procedure.

Troubleshooting Test Steps Values Results
Step 1 applies to C15 and C18 engines only.
1. Check the Gear Train Timing
The camshaft gear will be off a half tooth if the engine is timed when Cylinder # 6 is at Top Dead Center (TDC). The engine MUST be timed when Cylinder #1 is at TDC. The engine MUST be timed when Cylinder #1 is at Top Dead Center (TDC). Do NOT time the engine with Cylinder #6 at TDC as the camshaft gear will be off a half tooth.
Note: Remove the rocker arms before rotating the engine to prevent piston/valve damage from occurring.
A. If the engine is at TDC for cylinder 6, remove cam idler gear (B) and rotate the crankshaft 360 degrees and repin the flywheel.
B. Install idler gear (B).
C. Check timing mark (A).
D. Rotate the engine by hand 360° to ensure that the engine rotates freely. If the engine does not rotate freely, the engine is not timed correctly. Remove the front housing and check all timing marks. Refer to Testing and Adjusting, "Gear Group (Front) - Time" for the correct procedure.
E. Connect to Cat ET and clear the DTC.
F. Start the engine.
Diagnostic code
Result: After starting the engine the code is still present.
Proceed to Test Step 2.
Result: After starting the engine the code did not return.
Return the unit to service.

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.
