When replacing rear-chain fittings on a 1973 Honda CB500K, inspect the adjuster bodies as well as their screws. The complete set and custom screw pair contain different hardware. The black plastic guard is a separate cover whose mounting points must match the fitted swingarm.

1973 Honda CB500K · Rear-Chain Hardware Buying guide

Inspect the adjuster bodies before ordering screw replacements

Two bodies, two adjusting bolts and two nuts are named in the complete set. Joker Machine supplies two screws with nuts, while the guard covers the rear drive-chain area. Select according to the existing part needing repair.

Parts to consider

Honda CB750 / CB550 / CB500 Drive Chain Adjuster Set Bodies, bolts and nuts for both sidesThe current set contains two adjuster bodies, two adjusting bolts and two nuts, replacing 95014-19000. It supplies the described hardware for both sides of the compatible rear wheel.View part Honda CB Drive Chain Adjuster Screws ~ Black ~ Joker Machine ~ Replaces 90119-283-000 Black Joker Machine screws with nutsTwo black adjuster screws and two gold-cadmium-plated nuts are stated, against 90119-283-000. Their knurled, hex and Allen adjustment features do not make the pair a replacement for the separate bodies.View part 1971-78 Honda CB550K / CB500K Chain Cover Guard ~ Replaces 40510-323-000B Japanese-made black plastic chain coverThe guard lists reference 40510-323-000B and CB500K fitment. Compare the installed shape and mounting points; it is a cover for the drive-chain area rather than a replacement chain.View part

Select the hardware format the repair requires

If the adjuster bodies need replacement, the complete set expressly includes them alongside bolts and nuts. The Joker Machine package names screws and nuts instead. Assess the retained bodies before buying those custom screws so the order does not leave the actual missing component unaccounted for.

Use component function to separate similar drive names

An engine primary chain and its rubber dampers work in the internal primary-drive assembly. The rear axle adjusters work in a different drive arrangement, and a rear shock swingarm bushing supports a suspension mount. None of those internal-drive or shock components is described as a rear-chain adjuster body.

Buying questions answered

Which option includes the adjuster bodies?

The complete drive-chain adjuster set explicitly lists two bodies, two adjusting bolts and two nuts. The Joker Machine alternative lists two screws and two nuts, so inspect the existing bodies before choosing that option.

How can I compare the Joker Machine screws with access at the fitted axle?

Their knobs offer a knurled hand grip, an external hex for a wrench and an internal Allen drive. Compare those adjustment methods with the installed hardware and access. The package remains two screws with nuts, without replacement adjuster bodies.

Can I rely on CB500K fitment after a swingarm change?

Compare the actual guard mounts and the retained adjuster arrangement after modifications. The listed motorcycle application does not establish clearance or hardware fit for every substituted swingarm or custom rear-end configuration.
