1982 Honda CB650SC Nighthawk Master Cylinder Service Parts

Identify the master cylinder fitted to the 1982 CB650SC before choosing its repair parts. The two-screw reservoir package, internal rebuild kit and chrome cover address different needs. A universal replacement unit can require its own internals and lever even when mounted on the correct motorcycle.

1982 Honda CB650SC Nighthawk · Master Cylinder Service Parts Buying guide

Separate internal service from reservoir and cover repairs

Internal hydraulic service, reservoir replacement and a chrome-cover change call for different purchase scopes. Identify the unit actually fitted and inspect the affected components before combining those products.

Parts to consider

Confirm the internal repair-kit inventory

The internal rebuild-kit record identifies reference 45530-MA5-671 but does not itemize the supplied components. Confirm that inventory against the planned repair before adding individual seals or hardware.

Match the chrome cover by reference and interface

The chrome cover replaces 45513-MA5-671 and 45513-413-941. Compare those references and the mounting and sealing interface with the actual reservoir; a two-screw description alone does not establish fit on a changed master cylinder.

Master Cylinder Service Parts questions

Should I order a separate diaphragm with the reservoir kit?

The reservoir kit explicitly includes a diaphragm. Compare that included part with the repair list before adding another diaphragm for the same reservoir.

Does the separate chrome cover include screws and a diaphragm?

The written cover listing does not itemize those accessories. Confirm the supplied contents before ordering if your repair needs them, rather than treating the cover as the larger reservoir package.

Will the internal rebuild kit fit a replacement master cylinder?

Compatibility is not established by the motorcycle application. Identify the fitted master cylinder and obtain internal repair parts specified for that actual unit.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
