1972 Honda CB175K6 · Tank Caps & Hardware Buying guide

Decide what to retain on the tank

The chrome cap supplies an installed gasket, while the separate seal supports retaining an existing cap. Emblem clamp nuts have a different role and are ordered according to the fasteners needed.

Choose by the sealing assembly

Inspect the cap and the tank sealing surface together. A new rubber cannot correct an unsuitable cap attachment, and a changed tank may need a different cap altogether. The complete chrome cap includes its gasket, which helps avoid buying a redundant seal for that new assembly.

Retain the emblem with the right hardware

The tank-emblem clamp nut references 87311-634-600 and 87311-516-000. Compare the emblem and its attachment before ordering individual replacements. Count the actual missing or damaged retainers rather than assuming one fastener serves an emblem or a complete motorcycle.

Questions before buying

Will a replacement cap suit an aftermarket tank?

Confirm the filler-neck attachment and sealing arrangement on that tank first. A cap selected for the motorcycle model is not enough to identify an aftermarket tank, even where the tank looks similar to the original.

Do I need to add a gasket when buying the chrome cap?

The chrome filler cap comes with a gasket installed. A separate replacement seal is more relevant when retaining an existing compatible cap; check the repair scope before adding both to the same order.

Are the tank-emblem clamp nuts supplied as a pair?

They are sold individually. Examine the emblems and count the retainers being replaced. Match the clamp style and reference to the fitted emblem rather than borrowing a quantity from another tank or model.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
