Throttle Solenoid Adjustment, Diesel
IMPORTANT:
This final adjustment must be made after all other throttle speed adjustments. The
solenoid must be free to retract fully in order to turn OFF the High Amperage Pull
Circuit. Improper adjustment will result in solenoid failure and may damage the
electrical system.
With the engine OFF, manually retract the solenoid by grasping the piston, just ahead of the
boot, and pull to the fully retracted position.
Note:
The solenoid must retract and extend smoothly. If movement is impaired it may be necessary to
reposition the solenoid to improvement alignment.
With the solenoid piston fully retracted measure the distance between the High Speed Stop
Screw and the Throttle linkage using a .020 feeler gauge.
Adjust clearance at the Throttle Solenoid linkage only.
Do not adjust the High Speed Stop Screw������
Disconnect the linkage at the clevis and turn the clevis to lengthen or shorten as necessary.
Reconnect the clevis and measure again. Repeat until the measurement is correct.
