10 Teeth 300mm Forklift Clutch Disc — Heavy-Duty Friction Plate for 3-3.5 Ton Forklifts

This 10-teeth 300mm diameter clutch disc is a heavy-duty friction plate engineered for 3-3.5 ton diesel forklifts, the most common counterbalance capacity class in global material handling operations. The clutch disc is the central friction component in a manual transmission drivetrain, positioned between the engine flywheel and the pressure plate assembly. When the clutch pedal is released, the pressure plate clamps the disc against the flywheel, and engine torque is transmitted through the friction facings into the splined hub and onward to the transmission input shaft. When the pedal is depressed, the clamping force is released and power flow is interrupted, allowing gear changes. The 10-tooth hub spline count and 300mm outer diameter are critical dimensional specifications that must match the original equipment exactly — an incorrect spline count prevents installation entirely, while an incorrect diameter results in insufficient friction contact area or interference with the pressure plate housing.

Manufactured with high-friction coefficient organic or semi-metallic facing material riveted to both sides of a steel core plate, this clutch disc provides the consistent torque capacity needed for loaded forklift operation on gradients and during heavy acceleration. The hub incorporates a sprung-center design with multiple torsional damper coil springs that absorb the power-pulse vibrations inherent in diesel engine operation, providing smooth clutch engagement without judder or grab that would shock-load the transmission gears and cause operator discomfort. The facing material is formulated for high-temperature stability under the repeated friction heating cycles that occur during frequent stop-start forklift operation, resisting fade and maintaining consistent friction characteristics throughout the disc service life. The hub spline bore is precision-broached to ensure a precise sliding fit on the transmission input shaft with minimal radial play.

Direct replacement for 3-3.5 ton forklifts specifying 10-tooth spline count and 300mm clutch diameter, including Heli CPCD30-CPCD35, Hangcha CPCD30-CPCD35, Lonking LG30D-LG35D, TCM FD30-FD35, and Toyota, Komatsu models in the same capacity class using this spline and diameter specification. Always verify your existing clutch disc spline count, outer diameter, and spline bore diameter before ordering — these dimensions are the three critical fitment parameters. Replace the clutch disc, pressure plate, release bearing, and pilot bearing as a complete set for reliable, long-lasting clutch performance.
