1986 Honda CB450SC Nighthawk Pivot Cap References and Connection Bushing Details

Swingarm-related ordering for the 1986 Honda CB450SC Nighthawk distinguishes a genuine pivot dust cap from the bushing at the shock connection. The cap has a documented Honda supersession path, while the bushing has three stated measurements. Both are individual purchases, and neither listing gives a complete CB450SC piece count.

1986 Honda CB450SC Nighthawk · Pivot Cap and Shock Connection Buying guide

Identify the reference path and service location before counting pieces

The genuine cap is Honda 52144-356-005. It replaces several earlier cap references, and its quantity notes warn that applications differ. The shock-to-swingarm bushing is 40548-268-000, measuring 19 mm long, 22 mm outside diameter and 10 mm inside diameter, sold as an individual piece.

Keep the protective cap order tied to the retained pivot condition

Inspect pivot bushings or bearings, inner collar, seals and bolt for wear, corrosion and lubrication. The genuine cap protects the sealing area but cannot correct play caused by worn pivot parts. Those findings determine whether cap renewal is only one part of the required work.

Use every bushing measurement rather than a single matching bore

The written bushing dimensions describe length, outside diameter and inside diameter. Verify the required 40548-268-000 connection against all three. Individual sale gives no model-specific total and does not establish that the same bushing replaces the different hardware at an unidentified modified joint.

Common questions

How should I check an older Honda cap number against the current genuine replacement?

Confirm that the required cap follows the stated supersession to 52144-356-005 from 52144-268-000, 52144-286-000, 52144-329-000, 52144-356-003 or 52144-965-005. Also identify the fitted pivot arrangement, since an earlier swingarm change can affect the application being ordered.

Which details should be recorded for the bushing at the shock-to-swingarm connection?

Record 40548-268-000, 19 mm length, 22 mm outside diameter and 10 mm inside diameter, together with the shock-to-swingarm location. The bushing is sold individually. Confirm its required quantity and joint match instead of treating one matching measurement as complete identification.

How should cap quantity be resolved after earlier work changed the swingarm?

Confirm the installed pivot arrangement and its correct parts diagram before counting individual caps. The listing says some applications use one and others two, without a CB450SC total. Its original model coverage does not establish the quantity required by a changed swingarm.
