1977 Honda CB550F · Fuel Caps, Seals & Tank Mounts Buying guide

Decide between a complete cap and a seal-only repair

Inspect the cap hardware and seal before choosing the repair scope. Then check tank supports independently: front cushions and the rear support rubber have different profiles and references.

Account for the installed gasket and absent chain

The replacement cap is supplied with its rubber gasket already installed, so that package does not require an additional loose seal just to complete it. No chain is attached or included. Compare the fitted cap, filler connection and any retained tether arrangement before ordering.

Choose tank cushions by reference and position

The front rubber replaces 17611-283-010 and is sold individually, with two used per motorcycle. The linked rear cushion replaces 17613-286-000 and serves another support position. A change to the tank or its brackets warrants comparison with the actual mounting arrangement.

Your buying questions

When should I choose a loose seal instead of the replacement cap?

Inspect whether the existing cap hardware remains suitable and compare its seal profile with reference 17631-329-003. A seal-only repair addresses that rubber; choose the complete cap when its own assembly needs replacement, after checking the filler connection.

Will the new cap supply a replacement retaining chain?

No chain is included with this cap. Check the existing tether arrangement separately and compare the fitted cap connection before ordering. The pre-installed rubber gasket and any retaining chain are different package details.

Does one front cushion renew both front tank supports?

The front cushion is sold individually, and two are used per motorcycle. Count the pieces being replaced and order that quantity. The rear support rubber is a separate profile and purchase.

Not sure which part you need?
