A graph can then be created of the dynamic advance.Note: Worksheets are available in pads of fifty. Order one Special Instruction, SEHS8140. See Special Instruction, SEHS8580 for information on calculating the timing curve.After the timing values are calculated and the timing values are plotted, the dynamic timing should be checked with the 8T-5300 Engine Timing Indicator Group .
Operate the engine from 1000 rpm (base rpm) to high idle.
Continue running the engine now from high idle to 1000 rpm (base rpm).Unstable readings often appear below 1000 rpm.
Record the dynamic timing at each 100 rpm and at the specified speeds during acceleration and during deceleration.
Finally, plot the results onto the worksheet. Review the plotted values.Use Special Instruction, SEHS8580 to see the correct specifications for calculating the timing curve.You can find these specifications in three places:
The Operating Instructions inside the lid of the 8T-5300 Engine Timing Indicator Group
The Special Instruction, SEHS8580
The Engine Information Plate for the performance specification numberThe performance specification number can be used to refer to the TMI. Here, you will find the correct timing specifications to use.
Personal injury or death can result from not following the proper procedures.To avoid the possibility of injury or death, follow the established procedure.

Transducer in position (typical example) (10) 6V-7910 Transducer (13) Fuel injection line for No. 1 cylinder
The engine must be stopped before installing the timing indicator.
A high pressure fuel line must be disconnected and a probe must be installed into the flywheel housing.
Disconnect the fuel injection line (13) for the No. 1 cylinder. Slide the nut upward. Slide the nut out of the way. Attach the 5P-7436 Adapter (9). Tighten 5P-7436 Adapter (9) onto the pump bonnet. Turn adapter (9) onto the pump bonnet. Continue until the top of the bonnet's threads line up with the bottom of the opening in adapter (9) .
Attach 5P-7435 Adapter (11) onto injection transducer (10). Then, connect 5P-7435 Adapter (11) in the opening of 5P-7436 Adapter (9) .
Place fuel injection line (13) on top of 5P-7435 Adapter (11). Install 5P-7437 Adapter (7). Tighten the adapter to a torque of no more than 40 N m (30 lb ft).

Timing hole location (14) Plug
Remove the plug (14) from the flywheel housing. Install transducer adapter (5) into the hole that is remaining from the plug's removal. Tighten transducer adapter (5) only by a small amount.
Push magnetic transducer (3) into transducer adapter (5) until this adapter contacts the flywheel. Pull the magnetic transducer (3) out of the transducer adapter by 1.5 mm (0.06 inch). Then, lightly tighten the knurled locknut.

Transducer in position (3) 6V-2197 Magnetic Transducer
Connect the cables from the magnetic transducer (3) to 8T-5250 Engine Timing Indicator (1). Calibrate the indicator, and make any necessary adjustments.Note: See Special Instruction, SEHS8580 for more information on the calibration procedure.
Start the engine, and allow the engine to reach operating temperature. Then, run the engine at approximately one half throttle for eight to ten minutes. After this amount of time, measure the engine's timing.
Run the engine at increments of 100 rpm between 1000 rpm (base rpm) and high idle. Record the readings for engine timing, and then plot these readings onto a graph.Note: Use smaller increments to pinpoint the times when the timing advance starts. You can also use smaller increments to pinpoint the times when the timing advance stops.
Compare your results to the following values.
