1970 Honda CB750K · Clutch Plates & Springs Buying guide
Honda’s original wet clutch has seven friction discs, six steel plates and four springs. The friction stack originally uses six discs A and one disc B. Compare the fitted clutch and the replacement maker’s stack instructions as well as the individual catalog quantities.

Check friction-plate wear, steel-plate condition and the fitted clutch before building the order. Honda describes six friction discs A and one B in the original seven-disc stack. An aftermarket replacement may use a different design, so confirm its exact application and assembly instructions rather than assuming the original types are interchangeable or that the replacement is incompatible.
Review the retained bolts and washers alongside the spring replacement. Match them to the fitted clutch and its service information before adding hardware; replacing springs does not by itself establish that every fastener needs replacement.
Honda’s original stack uses six friction discs A and one B. The catalog lists seven of its individual replacement friction plate for the early CB750K, but does not explain that replacement design’s treatment of the original two types. Confirm the replacement maker’s complete-stack application and sequence for your clutch before ordering all seven.
Check clutch adjustment, friction-plate wear, steel-plate distortion and basket condition first. The performance spring listing says the springs do not repair worn plates, a notched basket or incorrect adjustment. Select springs after identifying the fault, and use the Honda procedure for the fitted clutch.
The tab washer replaces 90431-292-000; the special angled washer replaces 90481-292-000. Their shared 16mm description does not make them interchangeable. Match the reference and washer profile to its position in the fitted clutch.
