Installation & Application Notes

Always replace brakes in axle sets. Bed-in new brake pads with 8–10 moderate stops from 40 km/h. Check disc runout with a dial gauge — maximum 0.1 mm. Inspect caliper slides and pistons when replacing pads.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of a failing clutch friction disc is often a noticeable slippage during acceleration, where engine RPM increases but machine speed does not proportionally. If ignored, this slippage will worsen, leading to difficulty engaging gears and potential overheating of the transmission. Continued operation with a severely worn disc can result in loss of drive power and damage to other transmission components.

Installation Tip

Ensure the flywheel and pressure plate surfaces are clean and free of oil or grease before installation. Avoid overtightening the pressure plate bolts, as this can warp the components and lead to premature failure.

Service Note

Inspect the pressure plate, release bearing, and flywheel for signs of wear or damage when replacing the clutch friction disc.
