1983 Honda CB550SC Parts

Parts and fitment guide for your 1983 CB550SC

The 1983 CB550SC Nighthawk is a different model family from the earlier CB550K and CB550F. Its shaft drive and hydraulic clutch call for model-specific service parts; a shared CB550 name does not establish compatibility.

Identify your CB550SC (1983)

Confirm the full frame/VIN and engine markings against documentation for the 1983 CB550SC and its original market. The earlier CB550K and CB550F serial charts do not identify this Nighthawk.

For help locating identifiers, use our Honda CB model guide.

Separate master- and slave-cylinder repairs

The 1983 CB550SC has separate catalog repairs for the clutch master and slave assemblies. Master kit 08-0207 is distinct from pushrod-and-bushing kit 08-0301. Slave piston 29-0501 is also separate from seal kit 08-0310, which lists an oil seal, spring, piston cup and bleeder cap. Identify the worn or leaking assembly before choosing the repair parts.

Fitment questions

Why do the friction and steel clutch plates have different listed counts? They are different components of the clutch assembly. Friction plate 39-1112 lists six pieces for the CB550SC; steel drive plate 39-1241 lists five for the 1983 CB550SC. Keep the two product quantities separate and check the fitted assembly instead of ordering the same number of each by assumption.

Can I use the earlier CB550K fork-seal listing for the Nighthawk? The catalog lists 27-1028 for the 1983–84 CB550SC at 37 × 50 × 11mm, while the earlier K/F seal 27-1007 is listed at 35 × 48 × 10.5/11mm. These are replacement-seal dimensions. Match the installed forks and removed seals before ordering, especially after a front-end swap.
