1976 Honda CB550F · Gaskets & Oil Seals Buying guide

Choose top-end gaskets, overhaul gaskets or oil seals

The location of a leak and the parts removed during repair determine the sealing order. Compare flat gaskets, shaft seals and cap O-rings separately, then check each package against the work being carried out.

Parts to consider

1971-78 Honda CB550F / CB550K / CB500K Athena Gasket Set (Top End Set Only)

Compare the two Athena gasket scopes

The Athena top-end set is aimed at upper-engine gasket work, while the overhaul option is listed for broader engine service on this model. Compare the actual contents with your repair plan before choosing between them. Do not infer that a gasket-set name includes every shaft seal or every piece disturbed during disassembly.

Order caps and cover seals for their own locations

Individual alternator and head-cover gaskets are linked for smaller repairs, along with original-type tappet-cap O-rings. Check the cap design before selecting that O-ring set: it is specified for OEM-type covers. Custom finned caps use their own sealing arrangement, so a matching engine model alone does not settle the seal choice.

Common buying questions

How is the oil seal kit different from the Athena sets?

The oil seal kit has nine listed engine sealing pieces, including shaft and tach-drive seals. The Athena products are gasket sets for their stated repair scopes. Compare both contents rather than treating their names as identical coverage.

Can I buy a gasket for one removed cover?

Yes. Separate alternator-cover and cylinder-head-cover gaskets are linked here. Match the component, gasket shape and reference to the installed engine before choosing a single replacement, especially after previous cover or engine changes.

Will the stock tappet-cap O-rings fit custom finned caps?

The linked eight-piece O-ring set is limited to OEM-type tappet covers. A custom finned cap has a different stated sealing arrangement and its own included gasket. Identify the cap you have before buying replacement seals.
