This 430 mm clutch disc is listed for selected XCMG QY70K carrier configurations. No confirmed part number is supplied. Verify the disc diameter, gearbox-input spline, hub offset and thickness against the installed clutch before ordering.
Match the disc to the pressure plate
Record the carrier serial and clutch assembly reference. Compare the disc with the original and confirm that the pressure plate is the matching 430 mm configuration. Check spline engagement and hub clearance in the bell housing; a disc can share the same diameter yet fail to fit the shaft or sit at the correct depth. Ask the supplier to confirm the complete clutch combination.
Inspect why the old disc wore
Check for uneven friction wear, contamination, glazing or heat damage and inspect the flywheel and release mechanism. Follow the service manual for clutch installation and adjustment. If a disc has been slipping, diagnose the cause before replacing it. The page does not provide friction material, thickness limits or torque specifications.
Related QY70K components are the 430 mm pressure plate and the clutch release bearing. Confirm all three references and interfaces for the installed carrier.
