1985 Honda CB450SC Nighthawk Clutch Plate Groups and Spring Set

A clutch-stack order for a 1985 Honda CB450SC Nighthawk needs the plate groups kept distinct. The main friction and steel listings specify six individual pieces each. A different friction item and Steel Plate B each have a one-piece CB450SC requirement, while the spring package supplies the full four-spring set.

1985 Honda CB450SC Nighthawk · Clutch Stack Components Buying guide

Count individual plate groups without borrowing another model’s total

Main friction plates identify 22201-333-010 / 22201-ML4-610 and are supplied singly, six used. The separate friction listing requires one for the CB450SC despite its modern CB900 title reference. Main steels identify 23311-413-000, six used; 22321-333-010 is the single Plate B. The spring set contains four.

Read the CB450SC line on the multi-model friction listing

The separate friction product’s title highlights 22201-MAS-E00 and its modern CB900 application, where six are specified. Its CB450SC application instead names the older reference group and one required piece. Use that model-specific line, then preserve the exact Honda plate sequence and orientation during the planned service.

Use inspection results to set the replacement scope

The steel listings call for checks for warpage, heat spots and scoring, alongside the other clutch components. The spring guidance adds free-length measurement and basket/hub inspection. No numerical wear limit or stack order is supplied here; use the correct Honda service procedure when deciding which individual groups require renewal.

Parts ordering FAQs

How many of the multi-model friction item belong in the CB450SC order?

Its CB450SC line specifies one, with references 22201-302-000, 22202-ML4-610, 22202-ML4-611 and 22202-MV8-920. The six-piece 22201-MAS-E00 application belongs to the modern CB900F. Keep that item separate from the six main 22201-333-010 / 22201-ML4-610 friction plates.

Can the main steel plate count be used for Steel Plate B too?

The listings give different groups: six individually supplied 23311-413-000 steels and one 22321-333-010 Plate B for the compatible motorcycle. Preserve those identities and the specified Honda stack positions. The one-piece Plate B listing is not a six-piece steel-set purchase.

Which checks determine whether plates should be ordered alongside new springs?

Measure spring free length and inspect friction plates, steels, basket fingers and hub. The steel guidance also names warpage, heat spots and scoring. Use those findings to choose individual plate replacements; the four-spring package establishes spring supply, not the condition of the retained stack.
