1969 Honda CL450K2 · Drain Plug & Rotor Washer Buying guide

Check the oil-service location before selecting hardware

The magnetic plug is supplied with an O-ring and has defined external dimensions. The rotor washer is a separate 16 mm angled component; choose it by location and reference rather than diameter alone.

Check more than the threaded opening

The offered magnetic plug has a 45 mm outside diameter and is described as projecting 19 mm from the case. Compare surrounding clearance as well as the thread, particularly where guards or other equipment have been changed. These measurements describe this replacement plug, not a factory case specification.

Keep the rotor washer tied to its assembly

The rotor washer is an angled part with its own replacement reference. Match the correct location before ordering and use the applicable service manual for its orientation and fastening procedure. Do not substitute a generic flat washer merely because the nominal size appears similar.

Drain Plug & Rotor Washer questions

Does the magnetic plug arrive with its sealing O-ring?

Yes, the offered plug includes an O-ring. Still compare the thread and available case clearance before ordering, and follow the appropriate service information for installation rather than deriving a tightening specification from its socket size.

Will the magnet collect every kind of debris in the oil?

The magnet is described for capturing steel debris. Do not treat it as a substitute for the engine’s normal oil-service checks or as proof that all wear material will be collected.

Is the rotor washer chosen only by its 16 mm size?

No. Its angled form and replacement reference are also relevant. Match it to the rotor assembly being serviced and obtain the correct orientation and installation procedure from the applicable service information.
