Common Problems This Part Can Solve

• Difficulty disengaging the clutch pedal
• Uneven clutch release caused by a damaged fork
• Need for replacement after inspection shows fork wear or failure

Installation Notes and Tips

Verify Warner transmission application and casting number before installation. Inspect the clutch release components, pivot points, and related linkage for wear before reassembly. Because worn clutch forks cannot be repaired, replacement is the correct service approach when damage or fatigue is present.
