Forklift Clutch disc

Forklift Clutch Disc： Friction Plate for Mechanical Transmission Systems

A forklift clutch disc is the friction plate sandwiched between the flywheel and pressure plate that engages and disengages engine power to the transmission. When it wears, the clutch slips under load, produces a burning smell, or fails to engage completely. Kingstream stocks replacement forklift clutch discs with organic and ceramic friction materials for Toyota, Komatsu, HELI, Hangcha, TCM, Nissan, Mitsubishi, and Linde forklifts. Every disc is checked for spline fit, friction thickness, and runout before shipment.

Signs Your Clutch Disc Needs Replacement

A worn forklift clutch disc shows clear symptoms: the engine RPM increases but the forklift does not accelerate proportionally under load, indicating the disc is slipping against the flywheel; a burning smell similar to overheated brakes comes from the clutch housing, caused by friction material overheating during slip; the clutch pedal engagement point moves progressively higher as the disc wears thinner; and in severe cases, metal-on-metal grinding occurs when the friction material is completely worn away. Operating with a slipping forklift friction disc generates excessive heat that can warp the flywheel and pressure plate, turning a disc replacement into a full clutch kit job.

How to Order the Correct Clutch Disc

When replacing a forklift clutch disc, verify the spline count and diameter — the disc hub must match the transmission input shaft exactly. Check the friction material type: organic facings provide smoother engagement for standard warehouse operation, while ceramic forklift clutch friction plates offer higher heat resistance for heavy-duty applications with frequent starts and stops. Also confirm the disc diameter and thickness — an oversized disc will not fit the pressure plate, and an undersized one reduces contact area. The fastest way to get the correct forklift clutch plate is to send us your original Toyota, Komatsu, or HELI part number.

Quality Control at Kingstream

Every forklift clutch disc replacement we ship undergoes inspection: spline fit is checked on a reference shaft to confirm smooth engagement without binding; friction material thickness is measured at multiple points around the circumference; and disc runout is verified to ensure the facing runs true against the flywheel. We also inspect for friction material delamination, oil contamination, and hub spring fatigue. You receive a forklift transmission clutch disc that is ready to install and break in — no facing resurfacing or hub fitting required.
