1982 Honda CB650SC Nighthawk · Rear Chain-Adjuster Hardware Buying guide

Identify each rear adjustment piece before replacing it

The set contains six named pieces for two adjuster positions. Inspect the surrounding axle fittings and stopper surfaces independently, so a component outside that contents list is not overlooked when planning the rear-wheel hardware repair.

Compare the six-piece adjuster package

The set replaces reference 40543-425-000 and supplies two adjusters, two adjusting bolts and two nuts. Check which components remain sound at both axle positions. Stopper pieces and other nearby hardware are not named in that contents list, so assess those retained parts independently.

Do not derive final-drive length from the primary chain

The 50-link primary chain belongs inside the engine. That product’s link count cannot identify the external chain needed at the rear wheel. Confirm the actual final-drive chain and sprockets when planning a separate drive replacement.

Rear Chain-Adjuster Hardware questions

Can I rely only on swingarm marks to align the rear wheel?

No. Use both adjusters evenly, verify rear-wheel alignment with an accurate method and set chain slack to the Honda specification. Worn or mismatched index marks are not enough to establish alignment.

What should I inspect and recheck during chain adjustment?

Check the drive chain, both sprockets, axle, wheel bearings and adjuster seating. Tighten the axle and adjuster hardware using the service-manual procedure, then recheck chain slack after the axle is secured.

What should I check after a swingarm change?

Identify the installed axle-adjustment arrangement before relying on the original CB650SC application. Compare the adjuster mounting and fasteners with the altered swingarm, and resolve differing dimensions before purchase. A different swingarm may require different hardware even when the frame retains this model identity.
