Clutch Cover Assembly 3400125701 for DAF Trucks

OEM-specification clutch cover (pressure plate) assembly 3400125701, designed to fit DAF heavy-duty trucks at φ430*φ215*φ475. Cast iron housing, heat-treated diaphragm spring and precision dynamic balancing deliver stable release force and low driveline vibration under demanding operating cycles. Supplied factory-direct from an IATF 16949 certified plant in Jiangxi, China.

Installation & Maintenance Tips

1. When to replace. Persistent slip under load (RPM climbs without matching road speed), unusual pedal free-play, or driveline judder that is not engine-related usually points to a worn cover assembly.
2. Replace the disc at the same time. Cover wear almost always travels with disc wear. Replacing one side only leads to short cover life and repeat labour.
3. Flywheel surface matters. Inspect the flywheel face for hot-spots, cracks or runout beyond 0.10 mm before fitting the new cover. A glazed or warped flywheel will destroy a new cover quickly.
4. Bolts and torque. Tighten cover-to-flywheel bolts in a star pattern in 2–3 stages to the torque specified in the truck’s workshop manual. Do not rely on a generic torque value here — confirm against the model.
5. Break-in. For the first 500 km after replacement, avoid riding the clutch, hold-stop launches and high-load dragging in upper gears.

General guidance for heavy-duty truck clutch components. Always refer to the vehicle manufacturer’s workshop manual for model-specific torque values, runout limits and break-in procedures.

Product Features

• Heat-treated diaphragm spring — release force and clamp load held across the full RPM range, reducing pedal-effort drift as the facing wears.
• OEM dimensions — direct replacement for the OE number above with no modification to flywheel, bell housing or release mechanism.
• Precision dynamic balancing — residual unbalance controlled to low values, limiting driveline vibration and protecting the gearbox input shaft bearing.
• Cast iron housing — high thermal capacity for stop-start duty cycles on long-haul logistics, mining haul roads, construction sites and port container shuttle.

Application

Built for heavy-duty commercial vehicles running high annual mileage: long-haul logistics, mining transportation, construction vehicles and port container trucks. Matched to DAF truck series at φ430*φ215*φ475.
