1974 Honda CB550K · Clutch Plates Buying guide

Separate usage counts from package quantities

The plate descriptions give seven friction plates and six steel plates used on this application. In contrast, the spring set and O-ring pack state their package quantities directly. Keep those two kinds of quantity distinct.

The spring set states quantity and application

The spring description identifies a four-piece Japan-made set and specifically names the 1974 CB550K. It does not supply a spring rate, free-length measurement or quantified performance result. Use the application and package count without assuming a particular change in lever effort.

Small seals at the adjuster

The clutch adjuster O-rings are a pack of two and reference OEM 91301-704-000. Their application includes the CB550K from 1974 to 1978. Compare the fitted adjuster and old seal before choosing this pack; it is separate from the plate and spring orders.

Clutch questions

What friction plate count suits a 1974 CB550K?

The friction-plate description states seven used per motorcycle for the 1974–75 CB550K. It references OEM 22201-286-010. That is a usage count, so confirm package quantity rather than assuming one order contains seven plates.

And how many steel plates are needed?

The steel-plate description states six used per motorcycle for the CB550K from 1974 to 1976 and references OEM 22321-MT3-000. It does not explicitly describe a six-piece package or state a sold-each quantity.

What quantity is in the adjuster O-ring pack?

The adjuster O-rings are expressly a pack of two and reference OEM 91301-704-000. The application includes the 1974–78 CB550K. This package statement is distinct from the per-bike usage counts in the plate descriptions.
