Refer to Table 2 and find the engine current static timing ("deg BTC") with the corresponding timing dimension ("dim mm"). Because the current timing must be retarded by 2.5 degrees, subtract 2.5 from the current "deg BTC" and locate that value under the same heading. Refer to the corresponding "dim mm" for the correct timing dimension.An example is an engine that currently has a static timing of 20.0 degrees BTC and a 116.65 mm timing dimension. These values are listed under the heading of "High Speed High Overlap". The result of 20.0 minus 2.5 is 17.5. The 17.5 degrees BTC has a corresponding 117.62 mm timing dimension for the injector.Label the Engine for the New Timing Dimension

Typical engine Information PlateAfter the timing has been adjusted, alter the engine Information Plate. The Information Plate is glued between the two side covers at the rear of the engine on the right side of the cylinder block.You can carefully grind off the original timing dimension. Then etch the new timing dimension onto the plate. Otherwise, permanently remove the original timing dimension by grinding or by marking. Then, obtain a 236-1777 Instruction Plate (Fuel Injector Timing).

236-1777 Instruction Plate (Fuel Injector Timing) Stamp the new timing dimension and the part number of the fuel injector onto the instruction plate. The plate has an adhesive backing. Press the plate onto the engine below the engine original Information Plate.Additional Instructions and Assistance
For the procedure to set the fuel injector timing dimension, refer to the engine's Systems Operation/Testing and Adjusting, "Fuel Setting".
