Clutch Assembly Adjustment 14 inch Valeo Internal

  1. Measure the distance from the flywheel housing to the release bearing pads with 25 N·m (6 lb) of force pulling the bearing toward the transmission.
  2. 1.1. If 99.9 mm (0.750 in) on transmissions without a clutch brake, no adjustment is necessary.
    1.2. If 92.7 mm (0.50 in) on transmissions with a clutch brake, no adjustment is necessary.
    1.3. If the release bearing position is incorrect, loosen the lock rings and turn the adjusting nut in order to achieve the proper distance.
       • Spanner wrenches can be used to loosen and tighten the lock nuts.
       • T-3000 spanner wrenches from Great Lakes Tool Specialties (1-800-877-9618 ) can be used to loosen and tighten the lock nuts.

  5. • The KWIK-Adjust will re-engage at a quarter of a turn.
    • The flat on the bolt head will align with the flat edge of the bracket.

    Important: For synchronized transmissions, turn the adjusting bolt in order to obtain approximately 17.8 mm (0.7 in) clearance between the clutch cover and the release bearing.

    For non-synchronized transmissions, turn the adjusting bolt in order to obtain approximately 18.6 mm (0.73 in) clearance between the clutch cover and the release bearing.

  6. Turn the adjusting bolt in order to adjust the release bearing.
  7. • A counterclockwise movement of the adjusting bolt moves the release bearing toward the engine.
    • A clockwise movement of the adjusting bolt moves the release bearing toward the transmission.
  8. After the correct bearing position is achieved, ensure the KWIK-Adjust is engaged in the locked position.
  9. Release the clutch pedal in order to engage the clutch.
  10. Start the engine and check the clutch system for proper operation.
  11. Install the hand hole cover to the clutch housing.

Clutch Assembly Adjustment 13 inch Valeo Cable

  1. Apply the parking brake.
  2. Remove the return spring from the side of the transmission
  3. Loosen the jam and adjusting nuts and position both nuts away from the spacer block.
  4. Pull rearward on the clutch lever (Fork). Apply about seven pounds of force toward the engaged position (Rearward).
  5. Apply about six pounds of force to the opposite direction to position the clutch pedal against the rubber bump stop in the cap.
  6. With the force applied to both the cable and clutch lever, spin the adjusting nut down the threads until the adjusting nut is in contact with the spacer block. This will maintain tension on both the clutch lever and cable.
  7. Using a three eighths inch drive socket extension as a gage, position the end of the drive socket extension on the side of the adjusting nut.
  8. Position the jam nut down the threads against the side of the drive socket extension.
  9. Ensuring the jam nut does not move, remove the drive socket extension.
  10. Holding the jam nut in place, move the adjusting nut up the threads until it comes in contact with the jam nut.
  11. Ensure the clearance between the clutch fingers and the release bearing is one eight inch. Blue Point Gage, number 2034 can be used to check the clearance between the clutch fingers and the release bearing.
  12. If the clearance between the clutch fingers and the release bearing is not one eight inch, move (tweak) the adjusting nut until the clearance between the clutch fingers and the release bearing is achieved.
  13. Tighten
    Tighten the jam nut to 40 N·m (30 lb ft).

  14. Install the return spring.
  15. Using a tape measure the clutch pedal free play. Record and retain this information. After normal operation, occasionally check (measure) the clutch pedal free play. When the distance of clutch pedal free play becomes half of what was earlier recorded, an adjustment to the clutch cable is required.
  16. Check the clutch system for normal operation.
