Custom Forklift Transmission Clutch Disc — TCM, Lonking, Heli 2-3.5 Ton Compatible

This custom-application forklift clutch disc is manufactured to meet the exacting standards required for TCM, Lonking, Heli, and other major forklift brands in the 2-3.5 ton diesel segment. The clutch disc is the core friction component within the clutch assembly — sandwiched between the flywheel and pressure plate, its organic or semi-metallic friction facings grip both surfaces when the clutch is engaged, transmitting full engine torque to the transmission input shaft. When the driver depresses the clutch pedal, the pressure plate retracts and the disc spins freely on the transmission shaft, enabling smooth gear changes without grinding. A worn clutch disc — identifiable by slipping under load, shuddering during engagement, or a burning smell from overheated facings — progressively damages the flywheel and pressure plate surfaces, making timely replacement the most cost-effective maintenance decision for any forklift fleet.

Fabricated with a high-strength steel splined hub at its center, this disc engages the transmission input shaft with precision-cut involute splines that maintain zero-backlash torque transfer and permit smooth axial sliding for disengagement. The hub incorporates a torsional damper assembly — a series of coil springs arranged circumferentially within the hub flange — that absorbs combustion pulse vibrations and drive-line shock loads during clutch engagement. This damper mechanism is critical for protecting the transmission gears, differential, and axle shafts from fatigue damage caused by the abrupt torque spikes inherent to diesel forklift operation, especially during loaded starts on inclines or rapid direction changes. The friction facings are bonded to the disc carrier plate using high-temperature-resistant adhesive cured under controlled heat and pressure, with rivet-reinforced edges providing a secondary mechanical retention mechanism that prevents facing separation even if the adhesive bond deteriorates from sustained heavy-duty cycling. The friction material itself is a carefully formulated organic compound blended with aramid fibers, metallic particles, and friction modifiers that deliver consistent coefficient of friction across a wide temperature range while minimizing abrasive wear on the mating flywheel and pressure plate surfaces.

Compatible with TCM FD20-FD35, Lonking LG20D-LG35D, Heli CPCD20-CPCD35, and other 2-3.5 ton diesel forklifts sharing common clutch disc specifications. When replacing the clutch disc, always install a new release bearing and pilot bearing, inspect the flywheel surface for heat checking or scoring (resurface if necessary), and use a clutch alignment tool to center the disc before tightening the pressure plate bolts evenly in a cross pattern.
