1986 Honda CB700SC Steering-Stem Nuts & Washer

Identify the steering-stem hardware needing replacement on the 1986 CB700SC before ordering. The top nut, its separate washer and the thread-on head lock nut are different parts. Compare their positions and references, and inspect the fitted stem and seating surfaces for additional damage.

1986 Honda CB700SC · Steering-Stem Nuts & Washer Buying guide

Match each steering fastener to its exact position

A shared steering label does not make the hardware interchangeable. Use the installed assembly and service information to identify the top nut, washer or lock nut that the repair requires.

Keep the washer separate in the order

The top nut replaces reference 90304-425-000 and its washer replaces 90503-425-000. Both are sold individually. Inspect the two pieces and order each according to condition rather than assuming that a top-nut purchase supplies a matching washer automatically.

Identify the head lock nut

Honda’s CB700SC steering diagram separates the top-bridge hardware from the lock nut, tabbed lock washer and bearing-adjustment nut beneath it. Match the actual position before ordering 90302-425-830. The listed 90503-425-000 top-nut washer should not be assumed to supply the separate tabbed locking part.

Buying questions

Is the washer part of the top-nut package?

The washer is supplied separately, and both products are individual sale items. Inspect the original pieces and order the ones required by the condition of the assembly.

Is the listed top-nut washer the tabbed steering lock washer?

Do not treat them as interchangeable. Honda shows a separate tabbed lock washer below the top bridge, alongside the lock nut and bearing-adjustment nut. Identify the position and reference of the worn part before ordering the listed top-nut washer.

Will a new stem nut fix notchy steering bearings?

A nut is not a bearing repair. Honda calls for bearing and race inspection, and specifies replacing the bearing and its inner and outer races as a set when that replacement is needed. Confirm the cause of roughness before choosing hardware alone.
