1974 Honda CB360K0 Oil-Filter Rotor Locknut

The 16 mm slotted locknut shown here belongs at the CB360K0 oil-filter rotor. It is sold under a broad clutch-and-rotor product title, but this bike’s clutch retention is different. Match the original reference and service location before ordering the genuine Honda replacement.

1974 Honda CB360K0 · Oil-Filter Rotor Locknut Buying guide

Match the replacement nut to the rotor

The genuine Honda nut is supplied individually. Its replacement references include the original 90231-200-010 rotor nut, so identify that location rather than using the product title as a general engine-fastener guide.

Use the original reference to identify the part

Honda’s CB360 parts list identifies 90231-200-010 at the oil-filter rotor. The current genuine Honda replacement is 90231-KCS-651 and includes that original number in its supersession list. Check the fitted assembly if an engine swap or nonstandard rotor makes original-model identification uncertain.

Order by the service position

The nut is sold individually. Honda shows one at the rotor location, while the clutch uses an external snap ring. Inspect the old nut’s slots and threads and follow the service manual for the complete assembly; do not assume the broad product title makes it a clutch-center fastener here.

Buying questions

Is this a genuine Honda part or an aftermarket replica?

It is sold as a genuine Honda 90231-KCS-651 locknut. The replacement references include 90231-200-010, the original number shown for the CB360 oil-filter rotor location.

How many nuts does one purchase supply?

The product is sold individually. The CB360 parts list shows one at the oil-filter rotor location, so order for the specific service position rather than assuming a pack or a clutch-and-rotor set.

Does this nut retain the CB360K0 clutch?

Honda’s clutch procedure uses an external snap ring. This 16 mm slotted nut belongs at the oil-filter rotor; identify the assembly and original reference before selecting it from the broadly titled listing.
