1981 Honda CB400TB Hawk · Swingarm Caps & Shock Bushings Buying guide

Identify pivot caps and lower shock bushings separately

Four dust caps protect the original swingarm pivot arrangement, while two lower shock bushings serve the rear mounting points. Match the location before choosing between these individually supplied service parts.

Four caps for the original pivot assembly

Honda’s 1981 swingarm diagram shows four dust seal caps using the current 52144-356-005 reference. The genuine Honda cap is sold individually. Count which caps are missing or damaged before ordering; a full original-layout renewal calls for four, rather than a presumed pair.

The lower shock bushing is a separate repair

The replacement bushing references 40548-268-000 and measures 19 mm long, 22 mm outside and 10 mm inside diameter. Honda specifies two lower bushings on the original swingarm. These are separate from its pivot bushes, collars and dust caps, so identify where the wear is located.

Buying questions

How many dust caps should I order for a full refresh?

The original 1981 CB400T swingarm assembly uses four caps at the pivot arrangement. This genuine Honda product is sold individually, so order four only when renewing all those original positions. Check modified assemblies separately.

Is one lower shock bushing enough for both sides?

No. Each bushing is supplied individually, and the original motorcycle uses two lower shock bushings. Order the number that needs replacement after checking both mounting points and confirming the original bushing dimensions.

Will the dust caps remove play at the swingarm pivot?

The caps cover the pivot components; they do not replace the pivot bushes or collars. Have the source of play inspected before ordering and include any worn internal components required by the repair.

Not sure which part you need?

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