1974 Honda CB550K · Oil Service Buying guide
The stock arrangement uses a paper element inside a housing held by a centre bolt. The chrome spin-on unit does away with the housing, bolt and element in favour of a modern filter, so decide which system you are servicing.

Installation instructions for the chrome conversion have the threaded bung going into the engine before the filter itself is spun on. Once it is fitted, the original housing, centre bolt and paper element are no longer used, so skip ordering those.
The five-pack supplies oil-filter washers referencing 15414-300-000 for original-type paper elements. The drain-plug washer is a different listing, specified as 12 × 18 × 1mm. Match the repair location first; similar washer names do not establish the same dimensions or sealing arrangement.
The magnetic plug is listed as 12mm diameter × M1.5, replacing 92800-12000, with CB550K application. Confirm that listed specification against the installed plug; the source notation is not an independently verified thread measurement.
The element description offers O-rings, springs and washers separately. The washer five-pack supplies five pieces, while the factory-type bolt and spring have their own listings. Choose the associated parts required by the installed filter arrangement.
Its detailed application also names the CB500K, CB550F, CB750K and CB750F. The replacement reference is 15150-300-000. It is a strainer screen component, rather than a complete oil pump or the paper filter element.
