1970 Honda CB450K Chain Adjuster Components & Custom Screws

Decide which adjustment components need replacement on your 1970 Honda CB450K before ordering. An adjuster with its nut and bolt is a different package from two custom screws with nuts. Compare the fitted arrangement, then calculate quantity for the specific pieces required.

1970 Honda CB450K · Drive Chain & Adjusters Buying guide

Match the purchasing unit to the missing component

One product supplies the adjuster, nut and bolt. The Joker Machine option supplies two screws with nuts and three ways to turn each screw. Those access features do not establish a pair of complete adjuster assemblies.

Parts to consider

Honda CB Drive Chain Adjuster Screws ~ Black ~ Joker Machine ~ Replaces 90119-283-000 Black Joker Machine adjuster screw pairTwo screws with gold-cadmium-plated nuts, referenced to Honda 90119-283-000. Knurled knobs, hex surfaces and Allen access provide adjustment choices.View part Honda CB Drive Chain Adjuster with Nut & Bolt Adjuster with nut and boltIncludes an adjuster, nut and bolt; lists 95014-18000, 40543-390-000 and 40532-283-010. Order two if two assemblies are required.View part

Count components before comparing appearance

A custom screw pair addresses screw-and-nut requirements; it does not list the adjuster components supplied with the other product. Count the damaged or missing pieces first, then compare the package that covers them. The black finish alone cannot establish compatibility with a modified rear-wheel arrangement.

Check access on the fitted motorcycle

The custom knobs can be turned by hand at the knurled section, by a wrench on the hex, or with Allen access through the end. Compare that access with the installed arrangement. The description lists the screws and nuts, rather than a supplied set of adjustment tools.

Buying questions

How do I distinguish a screw pair from two complete adjusters?

Read the contents for the exact purchase. The Joker Machine package states two screws and nuts. The other product includes an adjuster with nut and bolt and instructs buyers to order two if needed. Do not transfer one package’s count to the other.

What should I check if the swingarm or rear wheel has been changed?

Identify the fitted adjuster arrangement and compare the listed references and required hardware. Neither product describes universal compatibility with every modified setup. Confirm the component match before choosing the custom screw finish or the number of adjuster assemblies.

Does the custom knob remove the need to check the rest of the adjustment hardware?

Its features concern how the screw is turned. Inspect the adjuster components, screws and nuts to establish the pieces required. The package does not promise that replacing the screws alone resolves every issue in the fitted arrangement.

Not sure which part you need?

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