SINOTRUK SITRAK Truck Clutch & Transmission System Parts C5H C7H ZF Clutch Pressure Plate Assembly WG9925160621/1

The SITRAK C5H/C7H WG9925160621/1 Clutch Pressure Plate Assembly is a key component of the clutch and transmission system, designed for compatible heavy-duty truck powertrains using the ZF 16S2530TO 16-speed transmission configuration. Installed between the clutch disc and the flywheel, the pressure plate generates the clamping force required to establish frictional contact between the clutch disc and flywheel, allowing engine torque to be transmitted into the gearbox during normal driving. When the clutch is released, the pressure plate moves away from the driven disc, temporarily interrupting torque transmission and allowing the driver to select or change gears. Because this component operates through repeated engagement and disengagement cycles under high engine torque, its diaphragm spring, friction surface, release mechanism, and mounting condition all influence clutch response and transmission operation. Excessive wear, uneven contact, weakened spring force, deformation, or incorrect installation can result in clutch judder, incomplete engagement, difficulty changing gears, or inconsistent pedal response. The WG9925160621/1 reference is associated with SINOTRUK SITRAK C5H and C7H applications and ZF 16S2530TO transmission configurations in current parts references. When replacing the pressure plate, the clutch disc, flywheel working surface, release bearing, clutch release mechanism, and mounting bolts should be inspected at the same time. Buyers should confirm the original part number, transmission model, clutch diameter, and existing clutch configuration before ordering to avoid mismatching components from different clutch specifications.
