  1. Place accelerator pedal in full throttle position. On vehicles with manual transmissions, adjust accelerator cable by inserting locking clip in correct slot of cable housing. Lever on pump should just touch stop screw. No tension should be placed on lever or cable to set position.
  2. On vehicles with automatic transmissions, put gear selector in "P" position and apply parking brake. Remove plastic cover from injection pump. Turn off engine. Loosen pedal cable adjuster at bracket on left side of transmission. Unhook pedal cable from transmission operating lever.
  3. Remove clip and ball socket of accelerator cable at pump lever. Ball stud of pump lever must travel 1.219-1.299" (31-33 mm) between position at idle stop to position at full throttle stop. Travel is adjusted by changing ball stud position in elongated hole of pump lever.
  4. Place ball socket and clip back on pump lever. Slip rubber boot off kickdown engagement spring housing. See Figure . Loosen both accelerator cable adjusting nuts. Push transmission operating lever to closed throttle position and hold or lock it there. Pull accelerator cable housing away from pump lever.
  5. Make sure kickdown engagement spring has not been compressed by pulling on cable housing. While holding housing in position, tighten accelerator cable adjusting nuts. Reconnect pedal cable to operating lever on transmission. Press accelerator pedal into kickdown position, making sure that kickdown engagement spring is compressed.
  6. With accelerator pedal held in kickdown position, turn pedal cable adjuster until transmission operating lever touches stop. Lock pedal cable adjuster in position. Be certain that pedal is at stop and that cable is free of tension.
  7. To recheck accelerator cable adjustment, push pump lever against idle stop. Make sure kickdown engagement spring is NOT compressed. Move transmission operating lever to closed throttle position. Press accelerator pedal to full throttle position.
  8. Push pump lever against full throttle stop. Check kickdown engagement spring to make sure that it is NOT compressed (no kickdown). Press accelerator pedal past full throttle point to stop. Make sure that transmission lever is against stop.
