1982 Honda CB750C · Honda Clutch Lock Nut Buying guide

Match the nut by reference and retaining position

The genuine Honda part has its own replacement and superseded references. Match those with the retained assembly rather than using nominal size alone. Surrounding washers and locking pieces should be inspected and identified separately.

An individual nut requires a complete hardware check

One nut is supplied per product. Compare it with the removed part and the assembly information, including the relevant replacement references. Keep washers and other retaining pieces separately identified so an individual nut purchase is not treated as a complete clutch-hardware kit.

Check changed assemblies by their own parts

An engine or clutch replacement can alter the required retaining hardware. Identify the actual assembly and its nut before ordering. Use the proper locking and tightening procedure during service, with the surrounding threads and retained hardware assessed as part of the repair.

Honda Clutch Lock Nut questions

Is this a genuine Honda part?

Yes, the nut is identified as genuine Honda, reference 90231-KCS-651. Compare that reference and the retaining arrangement with the actual clutch assembly before ordering.

How many nuts are supplied?

The nut is sold individually. Count the positions being serviced and inspect the surrounding hardware so the order covers the particular retaining repair required.

Can the 16mm description alone establish fit?

Also compare the reference, nut form and exact retaining position. This is especially important when another engine or clutch assembly has been installed in the original frame.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
