1982 Honda CB750K · Service Lock Nut Buying guide

Confirm the nut reference and installed position

This selection contains an individual genuine Honda 16mm lock nut. The listing covers multiple assembly uses across several models, so its exact application needs to be checked against the component being serviced.

Use the reference to identify the location

The product gives Honda reference 90231-KCS-651 and a list of superseded references. Compare those details with the parts diagram for the specific assembly on the motorcycle. A broad clutch and oil-filter-rotor title should not be read as proof that both locations apply to this bike.

Keep the nut separate from tools and washers

The nut is sold individually. Inspect related locking hardware and check the service procedure before deciding what else the repair requires. A special removal tool or a separate washer is a different product and is not established as included by the lock-nut listing.

Common questions

Is this a complete engine fastener assortment?

No. The current populated selection is an individual service lock nut. Review its reference and application before buying it rather than assuming the category contains a general hardware kit.

Does the broad product title establish its location on my CB750K?

The title spans multiple Honda applications. Confirm the exact nut reference and position in the diagram for the assembly being serviced, especially if the engine or clutch has been changed.

Does the nut come with its removal tool?

The listing describes the nut itself. Service tools and related washers are separate selections, so identify the complete repair requirements and review the individual product contents before ordering.
