1971 Honda CB175K1 · Tank Caps & Hardware Buying guide

Choose the right scope for a tank-side repair

A separate seal keeps a serviceable cap in use, while the chrome cap includes a gasket. Small mounting pieces have their own sold-each quantities and should be counted at the affected locations.

Avoid ordering the same seal twice

The chrome filler cap arrives with its gasket installed. Choose the separate cap rubber for a seal-only repair after checking that the retained cap remains suitable. If the tank has been replaced, compare its filler arrangement with the cap references rather than relying only on the bike year.

Check support and valve clearance separately

The linked rear tank holder replaces 17613-246-000 and is sold each, with one normally required. Check the retained mounting arrangement after any tank changes. If replacing the petcock too, allow for the replacement being longer than the original 1969–71 CB175K valve and compare its clearance.

Common ordering questions

Do I need a separate gasket for the complete chrome cap?

The complete cap includes a gasket already installed. A separately sold cap rubber is useful for a different job: renewing the seal while retaining a suitable existing cap.

Are the tank emblem clamp nuts sold as a pair?

They are sold individually. Count the fixings needed for the emblems you are repairing and compare references 87311-634-600 and 87311-516-000 with the retained hardware.

What changes if the motorcycle has a replacement tank?

Check the actual filler, petcock attachment and rear support arrangement. A tank swap can change those requirements, and the available petcock already has a longer-than-original qualification for the early CB175K application.
