1973 Honda CB450K · Swing Arm Parts Buying guide

Identify the pivot pieces without borrowing shock bushing dimensions

Thrust bushings reference 52109-283-300, caps 52144-283-010 and felts 52145-283-000. The locknut purchase includes its washer but no stated pivot bolt or sleeve. Shock bushing 40548-268-000 is individually supplied with separate length, OD and ID measurements.

Compare each bronze bushing at the actual component replaced

The thrust set gives 52109-283-300, while another bronze swingarm bushing product lists its own two-piece set without dimensions. Identify the removed component and confirm the required measurements if the swingarm is altered. Shared material and set quantity do not establish the same replacement part or a guaranteed modified fit.

Keep the shock mounting specification at that connection

Shock bushing 40548-268-000 is sold individually and measures 19mm length, 22mm OD and 10mm ID. Compare the original at the shock-to-swingarm mount before ordering. Those measurements do not specify the thrust bushings or metal pivot caps, and individual supply leaves the needed repair quantity to inspect.

CB450K buying questions

Does ordering the pivot locknut and washer provide a replacement bolt or sleeve?

Those additional components are not stated as included. The purchase names locknut 90354-268-000 and washer 90526-268-000. Inspect the retained bolt, sleeve and pivot sealing pieces, then identify any separate replacements required instead of assuming a complete pivot hardware kit.

How can I compare the bronze bushing sets for a non-original swingarm?

Identify which pivot component is being replaced and obtain its required measurements. The thrust product gives a Honda reference but no full dimensions, and the other bronze set also leaves dimensions unstated. Material and two-piece supply do not verify an altered swingarm’s fit.

Are felt seals confirmed inside the metal end-cap purchase?

The metal cap listing states two pieces against 52144-283-010. Felts are a separate left-and-right set at 52145-283-000. Compare both components removed and choose their required replacements independently rather than treating the cap package as a combined sealing kit.
