1977 Honda CB550F · Clutch plates & adjuster seals Buying guide
Six #1 friction plates and one #2 friction plate form the friction requirement. Steel plates are a separate order: check the engine application and distinguish the later regular plates from its additional plate B.

Honda’s later assembly uses five regular 22321-329-000 plates plus one separate 22322-390-000 plate B. The featured regular plate is listed for engines above 1139189; Honda’s change starts at that number. Confirm eligibility for an engine numbered exactly 1139189. Five regular plates alone are not a complete late steel stack.
The linked early steel plate is listed through engine 1139188, with six individual pieces required. That limit matters if an earlier engine or clutch has been fitted to the bike. Compare the engine number and assembly with Honda parts information before selecting steels; the two-pack adjuster O-rings are separate service items, not plate-stack components.
The stated CB550F requirement also includes one different friction plate #2. Both products are individual plates. Identify the existing assembly, then include the correct six-plus-one combination instead of treating six #1 plates as the complete friction order.
Honda begins the later five-regular-plus-plate-B assembly at 1139189, while the featured regular plate’s application says above that number. Confirm its eligibility for that exact boundary engine before ordering, and identify the separate plate B as well.
The later Honda assembly identifies 22322-390-000 as a separate plate B alongside five 22321-329-000 regular plates. Do not substitute an additional regular plate without verified application information. Inspect the removed parts and confirm the complete assembly before ordering.
