Rabbit Pickup L4-1588cc 1.6L DSL SOHC (1982)
Throttle Cable/Linkage: Adjustments
Automatic Transmission
1.
Run engine until vehicle reaches normal operating temperature.
2.
Mount sensor VW 1324, or equivalent, on valve cover (magnetic end). Since diesel engines do not need spark ignition systems, RPM signals
are generated through this vibration sensor.
3.
Connect tachometer positive cable to sensor post and tachometer negative cable to ground sensor cables to battery posts.
4.
Idle speed indicated on tachometer should be within 800 and 850 RPM.
5.
Adjust, if necessary. Loosen locknut, turn IN to raise idle speed or turn OUT to lower idle speed, then tighten locknut.
6.
Now accelerate engine briefly to ``full load'' position. Engine speed should be between 5300 and 5400 RPM for a non-turbo engine, and 5050 and
5150 RPM for a turbo engine.
7.
Adjust, if necessary. Loosen locknut, first turn OUT to raise maximum speed or turn IN to lower maximum speed, then tighten locknut. If
maximum speed is set too low, the engine will not produce full power. If maximum speed is set too high, the engine and injection pump can be
damaged by over revving of the engine.
8.
Locate the cable that runs between the accelerator pedal and the transmission. Loosen the adjusting nut and then disconnect the cable at the
transmission.
9.
Locate the cable that runs from the transmission to the injection pump control lever. At the injection pump end of the cable, disconnect the spring
housing from the ball stud by first removing the metal clip off of the cable end.
10.
Measure the travel distance of the ball stud from the idle position to the full throttle position. Adjust the ball stud if the distance is not 1 7/32 - 1
9/32 in. (31-33 mm).
11.
Reconnect the spring housing to the injection pump, making sure to install the metal clip. Remove the rubber boot from the spring housing.
Loosen the accelerator cable adjusting nuts.
12.
Have an assistant hold the transmission throttle lever against the idle stop. Hold the throttle lever on the injection pump at its idle stop and adjust
the cable to be just snug, without compressing the spring inside of the spring housing. Tighten the adjusting cable nuts.
13.
Have your assistant move the linkage towards full throttle until the lever at the injection pump makes contact with the full throttle stop screw.
Neither spring should be compressed at this point. If either spring is, a slight adjustment of the cable is allowable. Have your assistant move the
linkage fully in the full throttle direction. The inner spring should be fully compressed and the outer spring should be at least partially compressed.
14.
While your assistant is holding the linkage at the full throttle position, depress the accelerator pedal to its stop. Have your assistant reconnect the
throttle cable and adjust the cable to remove all slack and tighten the nuts on the adjusting cable.
15.
Have your assistant move into the passenger compartment and depress the accelerator pedal to the point where the injection pump linkage is
against the full throttle stop, but neither spring is compressed.
16.
Have your assistant fully depress the accelerator pedal and check to see if the inner spring is fully compressed and the outer spring is partially
compressed.
17.
Correct any adjustments that are necessary. Replace the rubber boot on the spring housing.
