1978 Honda CB550K Clutch Plates & Adjustment Seals

The 1978 Honda CB550K clutch listings identify two friction types and a steel plate described for all 1978 engines. Those descriptions state required pieces per motorcycle, which need a separate sale-quantity check. Compare the clutch and removed components before calculating the order or choosing seals.

1978 Honda CB550K · Clutch Plates & Springs Buying guide

Keep plate requirements separate from purchase quantities

Friction plates #1 and #2 have different references and requirements. The steel listing states five required pieces for 1978, all engines; compare those application statements with the fitted engine and confirm the supplied sale quantity before ordering.

Use the 1978 line in the steel-plate application

The steel description expressly lists 1978 CB550K, all engines, with five pieces required per bike. Its separate earlier-model serial conditions should not be applied to that 1978 statement. Compare the fitted engine and removed plates anyway, particularly where previous work changed the clutch or engine assembly.

Confirm spring information without guessing a corrected package

The separate spring kit describes DOHC application and six springs while also naming CB550K fitment. Clarify that combination before choosing it. For the plate order, distinguish the stated six #1 friction plates, one #2 and five steel pieces from any unconfirmed sale-package quantities; count the assessed clutch components first.

Common ordering questions

Does the current 1978 steel listing impose an engine-number cutoff?

Its 1978 CB550K line expressly says all engines and five pieces per bike. Compare the actual engine and removed plates with the listed reference. Do not import a separate earlier-model serial condition into that clearly stated 1978 application.

Do the friction descriptions establish a complete clutch pack?

They identify different friction types and state six #1 pieces and one #2 for the applicable model. Those are motorcycle requirements rather than an itemized complete-pack sale description. Confirm sale quantity and compare the fitted clutch before placing the order.

What does the clutch-adjuster seal package contain?

The separate listing identifies two clutch-adjuster O-rings with reference 91301-704-000. Compare the required seal position before adding that package; its contents are separate from friction plates, steel plates and the unresolved spring-kit application.
