Fuel Actuator Gain Adjustment Procedure
Press the "SELECT MODE" button on the DDT in order to display the "GOV GAINS" screen number "07" .
Press the "SELECT FUNCTION" button in order to display the "GOV GAINS" screen number "70" .
Press the "ALT2" button in order to increase the governor gain offset. Press the "ALT1" button in order to decrease the governor gain offset.
Adjust the governor gain offset in order to obtain the most stable engine operation.
The governor gain offset can be returned to the factory preset "0" value by pressing the "0" button on the DDT.Note: Adjustments to the "GAIN" value have a direct affect on the speed of the response signal that is sent to the fuel actuator whenever there is a difference between the desired rpm and the actual rpm. Excessive increase in the "GAIN" offset may amplify engine instability.Fuel Actuator Stability Adjustment Procedure
Press the "SELECT MODE" button on the DDT to display "GOV GAINS" screen number "07" .
Press the "SELECT FUNCTION" button in order to display "GOV STAB" screen number "71" .
Press the "ALT2" button in order to increase the governor stability offset. Press the "ALT1" button to decrease the governor stability offset.
Adjust the governor stability offset in order to obtain the most stable engine operation.
The governor stability offset can be returned to the factory preset "0" value by pressing the "0" button on the DDT.Note: Adjustments to the "STAB" value has an affect on the dampening of the command signal that is sent to the fuel actuator. Excessive increase in the "COMP" offset may cause the amplitude of the high frequency instability to increase.Fuel Actuator Compensation Adjustment Procedure
Press the "SELECT MODE" button on the DDT in order to display "GOV GAINS" screen number "07" .
Press the "SELECT FUNCTION" button in order to display "GOV COMP" screen number "72" .
Press the "ALT2" button to increase the governor compensation offset. Press the "ALT1" button in order to decrease the governor compensation offset.
Adjust the governor compensation offset in order to obtain the most stable engine operation.
The governor compensation offset can be returned to the factory preset "0" value by pressing the "0" button on the DDT.Note: Adjustments to the "COMP" value will have an affect on "slow hunting" stability characteristic and the amount of overshoot after a disturbance.Note: In order to prevent the zeroing out any adjustments that have been made, always use the "SELECT MODE" key to exit the screen numbers "70", "71" and "72" .Exhaust Bypass (Wastegate) Group

Rear View Of Engine (1) Exhaust system hardware (nuts, bolts and washers). (2) Axial stop plates. (3) Housing (exhaust bypass). (4) Bypass (wastegate) plate and shaft. (5) Plate. (6) Lever (exhaust bypass shaft). (7) Adjustable rod. (8) Lever (cross shaft to adjustable rod). (9) Cross shaft bearing assemblies. (10) Lever (wastegate end of cross shaft). (11) Adjustable rod (actuator to cross shaft). (12) Actuator shaft and lever. (13) Actuator assembly pointer.Use the following procedure in order to adjust the wastegate and the actuator linkage.
Apply 5P-3931 Anti-Seize Compound to the threads of all exhaust system hardware (1) that is exposed to the full exhaust temperatures.
Assemble the bypass (wastegate) plate and shaft (4) in housing (3) . Leave the mounting bolts loose.
Assemble axial stop plates (2) , plate (5) and the cover.Tighten the cover bolts to the following torque. ... 47 9 N m (35 7 lb ft)
Hold the wastegate plate in the fully closed position.Tighten the mounting bolts to the following torque. ... 12 3 N m (9 2 lb ft)
Install lever (6) on the exhaust bypass (wastegate) shaft.
Install the cross shaft through the cross shaft bearing assemblies (9) . The stamped end of the shaft should be toward the wastegate. Install lever (10) on the stamped end of the shaft.
