🔌 Function

Engages with its mating sleeve to lock the driving and driven parts together, carrying drive torque through the engagement faces.

• Drive jumping out under load
• Clonk or grinding as gear is engaged
• Engagement faces worn rounded, chipped or pounded over
• Metal particles found in the drive oil
• Selection stiff or refusing to hold
