Replacement Steps (Using CBR150R as an example)
- Drain the engine oil and remove the clutch cover (usually 6–8 bolts).
- Remove the pressure plate springs (note: loosen them evenly in a crisscross pattern).
- Take out the old friction plates and steel plates, and clean the inner wall of the clutch drum.
- Soak the new friction plates in engine oil for 15–30 minutes (Important!).
- Install the friction plates and steel plates alternately in the original order.
- Install the pressure plate and tighten the spring bolts to the specified torque evenly in a crisscross pattern.
- Add engine oil and check the clutch feel.
Frequently Asked Questions
Q: Why does the new clutch plate slip after installation?
A: New plates require a break-in period (about 200–300 km), and slight slippage is normal initially. If it still slips after the break-in period, check if the spring tension is sufficient or confirm if the friction plate specifications are correct.
Q: Do the steel plates need to be replaced at the same time?
A: It is recommended to replace them at the same time. Steel plates can warp due to heat after long-term use. Even if the friction plates are new, warped steel plates will affect the smoothness of clutch engagement.
