A genuine Honda hardware part

This genuine Honda 16mm lock nut is sold each. Use its replacement reference and the relevant assembly diagram to identify it rather than choosing on nominal size alone.

Keep application wording precise

The listing spans clutch-basket and oil-filter-rotor uses on different Honda models. Establish the correct location on the CB750C and retain the appropriate locking hardware and service procedure for that assembly.

Clutch Lock Nut questions

Is this nut sold as a pack?

It is sold individually. Determine quantity from the assembly being serviced rather than treating the product’s range of applications as a package count.

Will it replace an older Honda lock-nut reference?

The product records several superseded references, including 90231-200-010 and 90231-028-000. Compare your original reference and the relevant CB750C assembly before selecting the current Honda nut.

Can I select the nut only from its 16mm label?

Compare the reference, locking arrangement and original component as well. A nominal size alone does not verify the correct fastener for a safety-critical assembly.

Not sure which part you need?

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