Confirm the lock nut by its reference and location

A broad clutch and oil-filter-rotor product title does not identify every application on this motorcycle. Use the listed OEM reference and the correct parts diagram to confirm the nut needed for the specific assembly.

Use the parts diagram to identify the nut

The product is listed as genuine Honda 90231-KCS-651 and includes several replacement references. Confirm the required reference and location in the diagram for the actual assembly fitted. The model listing narrows the search but does not make every similarly sized lock nut interchangeable.

Keep hardware separate from the removal tool

This listing supplies an individual installed lock nut. A clutch center nut removal tool is separate workshop equipment and has its own working dimensions and drive fitting. Choose the replacement nut by its reference, then choose any service tool for the actual nut and procedure.

Common questions

Is this a lock nut or a removal tool?

It is an individual genuine Honda lock nut intended to remain in the specified compatible assembly. It is not a removal socket or other workshop tool. Choose any required service tool separately.

Can I use it anywhere a 16mm nut is needed?

No. The size description alone does not establish the correct threads or application. Confirm the OEM reference and assembly location against the relevant parts diagram before ordering this particular Honda lock nut.

Does the oil-filter-rotor wording prove that application on my bike?

The listing covers several Honda models and applications. That broad wording does not establish the nut’s location in every listed motorcycle. Confirm the reference in the specific diagram for your 1975 CB750K assembly before relying on it.
