Parts and fitment guide for your 1984 CB550SC

Identify your CB550SC (1984)

Compare the full frame/VIN and engine markings with records for the motorcycle’s original market. Use the complete CB550SC identity when selecting parts; earlier CB550K and CB550F charts are for different model families.

Check year, position and quantity

Fork oil-seal set 27-1028 explicitly lists the 1984 CB550SC with replacement dimensions of 37 × 50 × 11mm. Dust-seal set 27-1050 separately lists this year and supplies two dust seals. Compare the fitted forks before choosing either set; an oil-seal repair and a damaged outer dust seal call for different parts.

Fitment questions

Can the 1983 clutch master-cylinder listing be carried forward to 1984? Master kit 08-0207 and pushrod kit 08-0301 name the 1983 CB550SC, without a 1984 entry. The 1983–84 application of friction plate 39-1112 does not establish those hydraulic-component applications. Confirm the fitted master cylinder and its replacement parts before ordering for 1984.

Does the steel clutch-plate listing cover both Nighthawk years? Steel plate 39-1241 lists the 1983 CB550SC only, whereas friction plate 39-1112 explicitly includes 1984. Do not extend the steel-plate application or its listed count from the friction-plate coverage. Identify the installed clutch and obtain confirmation for the steel plates.
