- Damaged teeth of a clutch disc [gear shift]

Damage to the teeth of a clutch disc during gear shifts is a significant issue

that can affect performance and cause operational problems.

It is often caused by improper alignment or impact with the main shaft,

which can lead to rough shifts and potential system failure.

Regular inspections and proper installation are essential for prevention.

 Causes 

Damage by the main shaft

Clutch disc teeth may get damaged due to forceful contact or alignment issues with the main shaft.

This can result in rough shifting and increased wear over time.

Poor sliding due to stabbing

When the clutch disc doesn’t slide smoothly and engages abruptly ("stabbing"), teeth may wear down faster.

This often stems from slight misalignments during installation.

Poor transverse vibration due to stabbing

Abrupt engagement can also lead to transverse vibrations,

causing uneven wear on the clutch disc teeth and reduced shift quality.

 Maintenance & Caution 

Use a home position jig during disc installation

Using a home position jig ensures the disc is accurately aligned with the main shaft,

preventing excessive wear and promoting smooth sliding.

Maintain the home position when installing the transmission

Keeping the correct home position during transmission installation reduces unnecessary friction and vibrations,

extending the component’s lifespan and maintaining performance.
