1974 Honda CB550K · Engine Covers Buying guide

Replacing worn engine covers

The alternator, points and head breather covers replace different components. Their written contents also differ: the finned rocker cap includes a gasket, while the genuine Honda breather cover explicitly excludes its gasket.

Gaskets go with covers

The finned chrome rocker cap is sold each with a gasket included. The separate eight-piece tappet O-ring set is restricted to OEM-type covers. Identify the caps fitted before adding seals; an aftermarket cap’s included gasket does not establish compatibility with stock-type O-rings.

Check each cover’s supplied contents

The chrome points cover offers mounting hardware separately. The breather cover explicitly excludes its gasket, while the alternator cover description does not state an included gasket or fastener package. Check each purchase on its own terms instead of extending one cover’s contents to the others.

Engine cover questions

Is the alternator cover genuine Honda?

Yes. It is a genuine Honda part matching OEM 11632-323-003 and lists the CB500K, the CB550K from 1974 to 1976 and the 1975-76 CB550F Supersport.

Do the rocker caps come with gaskets?

Yes. The finned chrome rocker cap is sold individually with a new gasket included, replacing OEM 12361-300-000. Count how many caps your engine uses and order that quantity.

What is the breather cover for?

The description identifies the small cover on the cylinder head cover as part of the CB550 breather system. It names genuine Honda reference 12320-374-000, sold individually, and expressly says the matching gasket is not included.
