The 515KL-1601900 Clutch Pressure Plate and Housing Assembly is a heavy-duty, precision-manufactured component engineered to provide the high clamping force required to engage the driven plate against the flywheel under extreme torque loads. This assembly comprises a reinforced stamped steel housing, a high-performance diaphragm spring with optimized lever geometry, and a hardened pressure plate with a precision-ground friction surface, all designed to work in perfect harmony.
The diaphragm spring is manufactured from premium-grade spring steel, heat-treated to deliver consistent load-deflection characteristics and exceptional fatigue resistance, even after millions of clutch cycles. The pressure plate friction surface is induction-hardened and machined to a fine finish, ensuring excellent heat dissipation and resistance to scoring, which guarantees stable pedal feel and uniform wear across the driven plate facing.
Designed as a direct OEM replacement, the 515KL-1601900 guarantees that your HOWO chassis maintains its factory clutch engagement characteristics, providing the exact pedal effort, take-up point, and modulation that drivers expect. The assembly is dynamically balanced to minimize vibration, ensuring smooth operation at all engine speeds and reducing bearing loads.
With the 515KL-1601900, SINOTRUK HOWO sets a new standard for pressure plate durability in high-torque applications. Every unit undergoes rigorous testing for clamp load, lever height consistency, and runout, ensuring that each assembly provides reliable torque transmission and a long, trouble-free service life.
