Clutch identification FAQ

Answers buyers can use before requesting a quotation.

How do I identify a heavy-duty truck clutch?

Start with every stamped OE or cross-reference number, then confirm clutch diameter, spline count, spline diameter, hub profile, transmission and vehicle configuration. A visual match alone is not enough for final fitment.

Can I search by clutch part number?

Yes. Search the CHUANGJIN product database with the OE number or a cross-reference. If no exact record appears, send clear photos and dimensions so the technical team can compare the application.

What information should a B2B buyer send?

Send the vehicle model, engine, transmission, required quantity, destination market, OE reference, clutch diameter, spline details and product photos. This reduces quotation errors and speeds up application confirmation.
