Shacman Truck Clutch Driven Disc Plate DZ93189160307

The DZ93189160307 is a Φ430 mm heavy-duty truck clutch driven disc (clutch plate)​ originally specified by Shaanxi Automobile (SHACMAN) for the Delong series. It sits between the engine flywheel and the gearbox input shaft, engaging and disengaging engine torque to allow smooth starting and gear shifting. It is the friction-disc half of the clutch system-normally paired with cover assembly DZ93189160306​ and release bearing DZ93189160302.

430 mm pull-type design​ – standard for Chinese heavy trucks, gives high heat capacity and stable engagement under continuous load.

Damper-hub cushioning​ – torsional vibration dampers reduce gearbox shock during heavy-start and low-speed maneuvering.

High-temperature resistance​ – friction mix and riveted segments withstand repeated half-engagement on slopes or job sites without rapid glazing.

OEM interchangeability​ – direct replacement for SHACMAN Delong drivetrains; no flywheel or pressure-plate modification needed when matched with DZ93189160306 cover.

Long service life​ – rated for long-haul mileage; wear compensation stays within diaphragm-spring characteristics.

 

 

1. What are the signs that the DZ93189160307 clutch disc needs replacement?

Heavy-duty truck drivers should watch for three specific failure indicators that suggest the clutch disc friction material has worn down to its limit.

Clutch Slipping: The engine RPM increases rapidly, but the vehicle speed remains sluggish. This is especially noticeable when hauling heavy loads uphill.

Gear Shifting Difficulties: The transmission grinds when trying to engage a gear, or the gear stick feels unusually stiff and resistant to movement.

Abnormal Noises or Odors: A distinct burning smell emanates from the clutch housing area, or a sharp squealing noise occurs when the clutch pedal is depressed

 

2. How long does the DZ93189160307 clutch disc typically last?

The lifespan of this 430mm clutch disc heavily depends on driving habits and terrain, generally ranging from 50,000 to 100,000 kilometers under normal conditions. Aggressive driving behaviors can severely shorten this timeframe. The most damaging habit for this component is prolonged "half-clutching" or resting a foot on the pedal while driving, which causes continuous micro-slippage and accelerates heat buildup and material degradation.

3. Can I replace this disc without replacing the pressure plate?

Answer: It is highly discouraged. Because heavy-duty trucks carry massive loads, a worn disc usually leaves heat spots, cracks, or uneven wear on the pressure plate and flywheel. For long-term reliability, it is best to install it as a complete Shacman F3000/F2000 clutch kit (disc, pressure plate, and release bearing).

4. Which side of the DZ93189160307 disc faces the flywheel?

Answer: The flat side of the disc always faces the flywheel. The side with the protruding center hub and torsion springs must face away from the engine, toward the gearbox / pressure plate. Installing it backward will immediately damage the transmission input shaft or prevent the clutch from disengaging. 

 

5. What causes clutch disc contamination and how is it fixed?

Oil contamination is a common cause of clutch failure in heavy trucks. If oil leaks from the engine's rear main seal or the transmission's input shaft seal, it can seep onto the clutch disc. This creates a slippery surface that prevents proper friction, leading to severe slipping and overheating. The definitive solution requires fixing the source of the leak by replacing the faulty seals, thoroughly cleaning the entire clutch assembly, and installing a new clutch disc.
