1975 Honda CB550F · Gaskets & Oil Seals Buying guide

Match the sealing part to the opened joint

Oil around a cover does not automatically mean a shaft seal has failed. Identify the source and repair scope first, then compare the gasket shape, seal dimensions and kit contents with the engine in front of you.

Parts to consider

Choose a set for the work, not the name

The Athena set is intended for top-end work; the overhaul set has a broader stated purpose. Neither name establishes a complete bill of materials. Compare the product contents with your repair plan, then add only the individual gaskets or oil seals that are still needed.

Check covers and mating surfaces too

A new gasket cannot correct a damaged cover or worn seal surface. Compare the original gasket outline and reference, inspect the joint, and follow the Honda manual for preparation and assembly. For tappet caps, the linked O-ring set is limited to OEM-type caps; custom caps may seal differently.

Common buying questions

Which set should I buy for top-end work?

Start with the Athena top-end set and compare its pictured contents with the joints your job will disturb. If additional covers or shaft seals need attention, identify those pieces separately rather than assuming they are included.

Do the tappet-cap O-rings fit the finned chrome caps?

The eight-piece O-ring set is specified for OEM-type tappet covers only. The aftermarket finned chrome cap has its own included gasket; compare the cap and its sealing arrangement before choosing a replacement.

Can I replace a single alternator cover gasket?

Yes. An individual alternator cover gasket is linked here for reference 11691-323-306. Compare the cover and gasket outline with the installed engine, especially if covers have been replaced during an earlier restoration.

Not sure which part you need?
