1978 Honda CB550K · Drive Chain & Adjusters Buying guide

Choose complete adjusters or replacement screws

The complete set names adjusters, bolts and nuts, while the Joker Machine package names screws and plated nuts. The chain guard is a separate cover purchase, with its own reference and mounting comparison.

Compare the two packages component by component

The complete adjuster set contains two adjusters, two bolts and two nuts. The custom product names two screws with plated nuts. Compare both lists with the existing assembly and required work before choosing; a screw package does not establish that replacement adjuster bodies are supplied with it.

Treat the guard as a separate fitted component

The guard description identifies black plastic construction and reference 40510-323-000B. Compare its pictured shape and mounting points with the motorcycle, especially after rear-end changes. Choose it for the required cover replacement rather than assuming an adjuster order also includes a guard or its mounting pieces.

Common ordering questions

What does the complete adjuster set supply?

The itemized description names two chain adjusters, two adjusting bolts and two adjuster nuts, with reference 95014-19000. Compare those pieces with the current assembly and the components identified for replacement before ordering the set.

What features are named on the custom screws?

The Joker Machine description lists a knurled knob section, a hex for an open or box wrench and an Allen-wrench provision. Compare the pictured screw arrangement and supplied nuts with the fitted adjusters before choosing this custom option.

Does a primary-chain listing identify a drive-chain adjuster?

No. The primary-chain product is separately described as a primary chain, while the featured adjuster set names the adjustment pieces. Use the required part position and product description when selecting from similarly tagged drivetrain items.
