Material & Advantages

1. Integral high-strength cast iron clutch cover, anti-deformation under long-term high torque impact, good vibration damping performance

2. Alloy steel diaphragm spring overall quenching & tempering treatment, stable elastic force, anti-fatigue, resistant to high-temperature softening caused by frequent slipping

3. Ductile iron pressure plate working surface precision grinding + surface thermal refining, uniform heat dissipation, avoid local hot spot warping

4. Built-in automatic clearance compensation self-adjust mechanism, automatically offset friction disc wear clearance, maintain consistent pedal travel without manual adjustment

5. Standard OEM mounting hole layout, flywheel positioning spigot size, direct bolt-on installation without modification during overhaul

6. Optimized diaphragm spring finger design, light pedal operation force, reduce driver fatigue during long-distance transportation

7. Adapt to full-load highway logistics, mountain heavy climbing, frequent start-stop bulk cargo transport conditions

Application Scenarios

• Replace softened spring, warped friction surface original Eaton pressure plate marked 170002-31 for ZF/Fast 16-speed gearbox

• Fix vehicle faults: clutch slipping under heavy load, incomplete clutch separation, stiff gear shifting, power drop during climbing, inconsistent pedal travel

• Complete full clutch system disassembly overhaul and scheduled maintenance for logistics heavy truck fleets

• Assemble matched 430mm clutch disc and SACHS release bearing following Eaton official clutch assembly standards; full overhaul recommended to replace clutch disc, pressure plate and release bearing as a complete set
