1973 Honda CB500K Clutch Plate Counts & Spring Package

For clutch work on a 1973 Honda CB500K, distinguish the installed stack quantity from the quantity in each product package. The friction and steel plates are sold individually. The spring listing instead supplies a matched four-piece set, so its ordering unit is different.

1973 Honda CB500K · Clutch Plates & Springs Buying guide

Order individual plates and the matched spring set correctly

The current CB500K friction application specifies seven pieces; the 1972–73 steel Plate B application specifies six. Both plate listings supply one piece each. The Japanese-made spring package contains four springs for one compatible clutch, rather than one individual spring.

Choose quantities from the work on the actual stack

A quantity of one on either plate listing means one disc. Replacing all listed friction and steel pieces means seven friction plates and six Plate B discs, ordered as individual pieces. Inspect retained plates and the installed sequence before choosing a partial repair or full plate replacement.

Keep spring replacement separate from worn friction material

The four matched springs are supplied together. The source explains that firmer springs do not repair glazed friction material, warped steel plates or a notched basket, and lever effort can increase. Establish the clutch’s mechanical condition rather than treating a spring package as a substitute for worn stack components.

Common questions

How many steel Plate B pieces are listed for this year?

The detailed 1972–73 CB500K application specifies six discs under 22321-KA4-700, supplied individually. Compare that reference with the fitted clutch and engine before counting replacements. The friction listing separately specifies seven pieces, also supplied one per order unit.

How should a full friction-plate order be counted?

The CB500K requires seven friction plates under the listed application, and each purchase supplies one plate. Steel Plate B discs and the four-spring package have separate quantities. Verify the installed stack if the engine or clutch has been replaced or modified.

What should influence the decision to fit the performance springs?

The matched Japanese-made package contains four springs and is intended to be installed together. The source notes increased lever effort is possible. Springs do not correct glazed friction material, distorted steel plates or basket wear, so evaluate those parts independently.
