1971 Honda CB350K3 Swingarm & Shock Bushes

The lower shock bush and swingarm pivot parts occupy different places on the K3. Identify the worn location before ordering: a lower shock bush is not a swingarm pivot bush, and a dust cap is separate from the sealing rubber used with it.

Order lower shock bushes by position

Honda specifies two lower shock bushes referencing 40548-268-000 on the K3. The replacement is sold each and has stated 19 × 22 × 10mm dimensions. Inspect both sides, but do not confuse those bushes with the separate pivot bushes inside the swingarm.

Keep the cap and seal scope clear

The genuine Honda dust cap replaces earlier references including 52144-268-000 and is sold individually. The original K3 uses two caps with separate sealing rubbers. The grease fitting pack supplies two fittings; neither product should be treated as a complete swingarm bearing and seal kit.

Buying questions

Does the lower shock bush replace a swingarm pivot bush?

No. The 40548-268-000 replacement belongs at the lower shock mounting point. The swingarm pivot has its own bushes, so identify the location of play before ordering a replacement.

How many dust caps does an original K3 use?

Honda lists two swingarm dust caps, and the current genuine replacement is sold individually. The original sealing rubbers are separate parts; do not assume a cap order supplies those too.

How many grease fittings are supplied?

The grease fitting product is a pack of two. That is the package quantity, so compare the fittings on the installed swingarm and order for the positions being serviced rather than assuming two packs are needed.

Not sure which part you need?

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