The listed stack uses seven type 1 friction plates and one type 2, with six ordinary steel plates and one riveted steel B plate. These are individual components, not interchangeable descriptions of a complete kit. Follow the Honda assembly sequence rather than grouping all similar-looking plates together.
Inspect springs against the service limits instead of assuming stronger springs will cure every slipping clutch. The rubber-damper repair kit addresses a separate part of the assembly; it does not supply the friction and steel plate stack.
First check for insufficient cable free play. If adjustment is correct, inspect friction wear and spring condition. Honda lists both worn discs and weak springs as possible causes, so diagnose the assembly before ordering.
Too much free play can prevent full release, and warped steel plates can cause creeping with the lever pulled in. Check adjustment, plate flatness and assembly order rather than replacing friction plates again.
Use the specified plate type and stack arrangement. The riveted B plate is a distinct double-plate component; the catalogue does not establish an ordinary single plate as a substitute.
