Features of MACK Clutch Kit
High-strength Durable Materials for Extended Service Life Under Heavy Loads
Pressure Plate Assembly
High-toughness ductile iron housing with integral quenching and hardening treatment, resistant to bump impacts and less prone to warping and deformation under high temperatures. Reinforced diaphragm spring delivers excellent fatigue resistance, maintaining stable clamping force without degradation during long-term heavy-load operation.
Built-in flow-guiding heat dissipation grooves rapidly dissipate high frictional heat, mitigating thermal damage caused by frequent half-clutch engagement on mountain slopes.
Clutch Disc (Multiple Formulas Available)
Organic variant for long-haul trunk routes: Stable friction coefficient, light pedal feel and low noise, ideal for standard-load highway freight transport.
Ceramic / copper-based powder metallurgy variant for heavy-duty engineering use: Maximum heat resistance up to 380°C, effective against disc burning and heat fade. Service life increases by over 60% under high-frequency start-up conditions for muck transport, mining and steep slope operations.
Thickened wear-resistant friction linings and high-rigidity steel core disc. Built-in multi-stage shock-absorbing springs and damping rubber blocks absorb engine torsional vibration, protecting transmission gears and drive shafts.
Complete Matching Release Bearing & Guide Bushing
The full kit includes pressure plate, clutch disc, release bearing, guide bushing and mounting shims. One-stop replacement eliminates separate purchase of individual spare parts, enabling complete repair in a single service session.
3. Self-adjusting Structure & Light Pedal Comfort to Reduce Driver Fatigue
Mainstream models are equipped with an automatic clearance adjustment mechanism. It automatically compensates clamping travel as the friction disc wears, eliminating frequent manual clutch adjustments and drastically cutting fleet maintenance workload.
Optimized diaphragm spring mechanics deliver a lighter pedal actuation force, preventing leg and foot fatigue during long-distance driving. Smooth linear engagement ensures no jerking or shaking when starting under heavy loads.
4. Superior Stability in Severe Working Conditions (Aligned with MACK's Engineering Heritage)
Dustproof and waterproof sealed structure prevents contaminants from entering to wear splines and bearings in muddy, wet worksites and mining areas with water spraying.
Precisely calibrated dynamic balance at factory delivery ensures no shaking or resonance at high speeds, reducing abnormal wear on flywheels.
Endurance standards matching military-grade operating conditions. Failure rate is far lower than generic aftermarket parts during continuous high-intensity operations in extreme cold, high heat and long-distance scenarios.
