1. Adjust linkage so that the release bearing is at its most rearward position with the clutch pedal up.
2. Note position of the release fork. Optimal position is straight up and down. Any tilt forward removes travel of the clutch and causes poor release.
3. Place tool across the face of the bell housing (with the ¼” spacer facing toward the engine).
4. Record measurement (A).
5. Remove tool from bell housing and relocate to the pressure plate with the ¼” spacer resting on the release levers of the pressure plate.
6. Measurement (A) and (B) must be the same for free travel and linkage adjustment to work correctly.
