SHIFT CABLE



See Figures 1 and 2

  1. Start the engine. Shift the transaxle to R, checking that reverse gear engages.
  2.  
  3. Shut the engine off and disconnect the negative battery cable.
  4.  
  5. Remove the console.
  6.  
  7. On 1984-88 Accord, place the selector lever in D. On 1988 Prelude, place the selector lever in R. On 1989 Accord and Prelude, place the selector lever in N or R. On 1990-95 Accord and Prelude, place the selector lever in N. Remove the lock pin from the cable adjuster.

Fig. Fig. 2: The cable must be perfectly aligned in the adjuster

There are 2 holes in the end of the shift cable. They are positioned 90 degrees apart to allow cable adjustments in1/4turn increments.

  1. If not perfectly aligned, loosen the locknut on the shift cable and adjust as required.
  2.  
  3. Tighten the locknut and install the lock pin on the adjuster. If the lock pin feels like it is binding when being installed, the cable is still out of adjustment and must be adjusted again.
  4.  
  5. Connect the negative battery cable, start the engine and check the shift lever in all gears. Install the console.
  6.  

THROTTLE CONTROL CABLE



Carbureted Engines
1984-88 MODELS

See Figures 3, 4 and 5

  1. Start the engine and warm it up to normal operating temperature. The cooling fan must come on at least once.
  2.  
  3. Make sure the throttle cable play, idle speed and automatic choke operation are correct.
  4.  
  5. Turn the engine off and disconnect the negative battery cable.
  6.  
  7. Disconnect the throttle control cable from the control lever.
  8.  
  9. If the vehicle is equipped with a dashpot on the linkage, disconnect the vacuum hose from the dashpot, connect a vacuum pump and apply vacuum. This simulates a normal operating amount of pull by the dashpot, as if the engine were running.
  10.  
  11. Attach a weight of about 3 lbs. (1.36 kg) to the accelerator pedal. Raise the pedal, then release it. This will allow the weight to remove the normal free-play from the throttle cable.
  12.  
  13. Secure the throttle cable with clamps.
  14.  
  15. Place the end of the throttle cable on the shock tower.
  16.  
  17. Adjust the distance between the throttle control cable end and the locknut closest to the cable housing to 3.366 in. (85.5mm) on all except 1988 Prelude. The distance on 1988 Prelude should be 6.22 in. (158mm).
  18.

Fig. Fig. 3: Measure the cable carefully, as it must be adjusted precisely

  1. Insert the end of the throttle control cable into the groove of the throttle control lever. Insert the throttle control cable into the bracket and secure with the other locknut. Make sure the cable is not kinked or twisted.
  2.

  1. Check that the cable moves freely by depressing the accelerator.
  2.  
  3. Remove the weight on the accelerator pedal and push the pedal to make sure there is at least 0.08 in. (2mm) play at the throttle control lever.
  4.

Fig. Fig. 5: Check the play at the control lever

  1. Connect the negative battery cable and the vacuum hose to the dashpot.
  2.  
  3. Start the engine and check the synchronization between the carburetor and the throttle control cable. The throttle control lever should start to move as the engine speed increases.
  4.  
  5. If the throttle control lever starts to move before the engine speed increases, turn the cable locknut closest to the cable housing counterclockwise and retighten the locknut closest to the cable end.
  6.  
  7. If the throttle control lever moves after the engine speed increases, turn the locknut closest to the cable housing clockwise and retighten the locknut closest to the cable end.
  8.  

1989-90 MODELS
  1. Start the engine and bring it to normal operating temperature. The cooling fan must come on at least once.
  2.  
  3. Make sure the throttle cable free-play and idle speed are correct.
  4.  
  5. On 1990 Prelude, disconnect the vacuum hose from the throttle controller and connect a vacuum pump to the controller and apply vacuum.
  6.  
  7. Apply light thumb pressure to the throttle control lever. Have an assistant depress the accelerator. The lever should move just as the engine speed increases above idle. If not, loosen the nuts on the control cable at the transaxle end and synchronize the control lever to the throttle.
  8.  

The shift/lock-up characteristics can be tailored to the driver's expectations by adjusting the control cable up to 0.11 in. (3mm) shorter than the synchronized point.

Fuel Injected Engines

See Figures 6, 7 and 8

1985-88 MODELS
  1. Loosen the locknuts on the throttle control cable.
  2.  
  3. Press down on the throttle control lever until it stops.
  4.  
  5. While pressing down on the throttle control lever, pull on the throttle linkage to check the amount of throttle control cable free-play.
  6.  
  7. Remove all throttle control cable free-play by gradually turning the locknut closest to the cable housing. Keep turning the locknut until no movement can be felt in the throttle link, while continuing to press down on the throttle control lever, pull open the throttle link. The control lever should begin to move at precisely the same time as the link.
  8.  

The adjustment of the throttle control cable is critical for proper operation of the transaxle and lock-up torque converter.

  1. Have an assistant depress the accelerator to the floor. While depressed, check that there is at least 0.08 in. (2mm) play in the throttle control lever. Check that the cable moves freely by depressing the accelerator.

1989-95 MODELS
  1. Start the engine and bring it up to operating temperature. The cooling fan must come on at least once.
  2.  
  3. Make sure the throttle cable free-play and idle speed are correct.
  4.  
  5. On dashpot equipped vehicles, disconnect the vacuum hose from the dashpot, connect a vacuum pump and apply vacuum. This simulates a normal operating amount of pull by the dashpot as if the engine were running.
  6.  
  7. Remove all throttle control cable free-play by gradually turning the locknut.
  8.  
  9. Apply light thumb pressure to the throttle control lever to move the throttle linkage. The lever should move just as the engine speed increases above idle. If not, loosen the nuts on the control cable at the transaxle end and synchronize the control lever to the throttle.
  10.  

The shift and lock-up characteristics can be tailored to the driver's expectations by adjusting the control cable up to 0.11 in. (3mm) shorter than the synchronized point.
