Check the complete chain-adjuster set contents

The adjuster package lists two adjusters, two adjusting bolts and two nuts. Compare those contents with the parts missing or worn on your motorcycle.

Parts to consider

1979-83 Honda CB750 / CB650 Drive Chain Adjuster Set ~ Replaces 40543-425-000 Complete DOHC Chain Adjuster SetIncludes two chain adjusters, two adjusting bolts and two nuts. Listed against Honda reference 40543-425-000 for CB750K applications including 1980.View part

Inventory the fitted parts before choosing the package

Record the condition of the adjusters, adjusting bolts and nuts on both sides. The complete set covers those named pieces; account for any other hardware required by the fitted assembly separately.

Recognize the separate primary-chain application

The primary-chain product describes an internal engine chain with its own reference. It is not the rear-wheel drive chain and does not replace an adjuster or stopper. Keep that product out of a rear-wheel adjustment order unless you are also planning a separately identified internal engine repair.

Common questions

What does the complete adjuster set include?

The set contains two chain adjusters, two adjusting bolts and two nuts. Stopper plates are not named in its contents list.

What reference identifies the complete adjuster set?

The set replaces reference 40543-425-000. Match it to the fitted adjuster assembly before ordering.

Is the primary chain a replacement rear-wheel drive chain?

No. Its listing describes the primary chain for the engine application and gives a separate reference. Rear-wheel adjustment parts serve another assembly. Do not treat the shared category tag as proof that the chains perform the same job.

Not sure which part you need?

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