    SHIFT CABLE



    See Figures 1 and 2

    1. Start the engine. Shift the transaxle to R, to see if the reverse gear engages.
    2.  
    3. Shut the engine off and disconnect the negative battery cable.
    4.  
    5. Remove the console.
    6.  
    7. On 1988 models, place the selector lever in D. On 1989-91 models, place the selector lever in N or R. On 1992-95 models, shift to N. Remove the lock pin from the cable adjuster.
    8.  
    9. Check that the hole in the adjuster is perfectly aligned with the hole in the shift cable.
    10.  

    There are two 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.
    4.  

    If the lock pin feels like it is binding when being installed, the cable is still out of adjustment and must be adjusted again.

    1. Connect the negative battery cable, start the engine and check the shift lever in all gears. Install the console.
    2.

    THROTTLE LINKAGE



    Carbureted Engines
    THROTTLE CONTROL CABLE BRACKET
    1. Disconnect the negative battery cable.
    2.  
    3. Disconnect the throttle control cable from the throttle control lever.
    4.  
    5. Bend down the lock tabs of the lock plate and remove the two 6mm bolts to free the bracket.
    6.  
    7. Loosely install a new lock plate.
    8.  
    9. Adjust the position of the bracket by measuring the distance between the cable housing side of the bracket and the bracket side edge of the throttle control lever. Measure between the same points that the cable would pass through the bracket and lever.
    10.  
    11. Tighten the two 6mm bolts when the measurement is 3.287 in. (83.5mm). The bolts should be tightened to 9 ft. lbs. (12 Nm).
    12.  

    Make sure the control lever does not get pulled toward the bracket side as the bolts are tightened.

    1. Bend up the lock plate tabs against the bolt heads, connect the throttle control cable and connect the negative battery cable.
    2.

    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. Check the distance between the throttle control lever and the throttle control bracket and adjust as necessary.
    6.  
    7. Turn the engine off and disconnect the negative battery cable.
    8.  
    9. Disconnect the throttle control cable from the control lever.
    10.  
    11. If the vehicle is equipped with a dash pot, disconnect the vacuum hose from the dash pot, connect a vacuum pump and apply vacuum. This simulates a normal operating amount of pull by the dash pot, as if the engine were running.
    12.  
    13. Attach a weight of about 3 lbs. (1.35 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.
    14.  
    15. Secure the throttle cable with clamps.
    16.  
    17. Lay the end of the throttle cable aside on Civic and CRX.
    18.  
    19. Adjust the distance between the throttle control cable end and the locknut closest to the cable housing to 3.366 in. (85.5mm).
    20.  
    21. Insert the end of the throttle control cable in the groove of the throttle control lever. Insert the throttle control cable in the bracket and secure with the other locknut.
    22.  

    Make sure the cable is not kinked or twisted.

    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. (2.0mm) play at the throttle control lever.
    4.  
    5. Connect the negative battery cable and the vacuum hose to the dash pot.
    6.  
    7. 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.
    8.  
    9. 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.
    10.  
    11. 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.
    12.

    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. (2.0mm) play in the throttle control lever. Check that the cable moves freely by depressing the accelerator.
    2.  

    1989-91 Fuel Injected Models
    THROTTLE CONTROL CABLE
    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 dash pot equipped vehicles, disconnect the vacuum hose from the dash pot, connect a vacuum pump and apply vacuum. This simulates a normal operating amount of pull by the dash pot as if the engine were running.
    6.  
    7. Remove the throttle cable free-play.
    8.  
    9. Apply light thumb pressure to the throttle control lever, then work the throttle linkage. The lever should move just as the engine speed increases above idle. If not, proceed to the next step.
    10.  
    11. Loosen the nuts on the control cable at the transaxle end and synchronize the control lever to the throttle.
    12.  

    The shift/lock-up characteristics can be tailored to the driver's expectations by adjusting the control cable up to 0.12 in. (3mm) shorter than the synchronized point.

    1. Remove the vacuum pump and connect the vacuum hose to the dash pot.
    2.  

    1992-95 Models
    THROTTLE CONTROL CABLE

    See Figure 6

    1. Verify that the throttle linkage is in the full-closed position.
    2.  
    3. Loosen the locknut of the throttle control cable at the throttle linkage.
    4.  
    5. Remove the free-play of the throttle control cable with the locknut, while pushing the throttle control lever to the full-closed position.
    6.  
    7. Tighten the locknuts.
    8.  
    9. After tightening, inspect that the throttle control lever movement is synchronized.
    10.  

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