1977 Honda CB750K · Drive Chain & Adjusters Buying guide

Separate rear-wheel adjustment from internal primary drive

Check which rear-wheel pieces are missing

The adjuster package contains two adjusters, their two bolts and two nuts. The steel stopper pair is a separate listing. Compare those contents with the rear-wheel assembly on your motorcycle so replacement adjusters are not mistaken for a package containing every nearby plate or mounting component.

Primary drive is a separate engine repair

The featured primary chain pair is an internal engine component, and the related tensioner is identified specifically for the primary chain system. Neither replaces the cam chain or the external chain driving the rear wheel. Keep these engine items on a separate repair list from rear-wheel adjustment hardware.

Common questions

Does the adjuster set include two sides of hardware?

The listing contains two chain adjusters, two adjusting bolts and two adjuster nuts. The stopper plates are listed as a separate pair. Compare the installed assembly and its missing or worn pieces before combining the sets.

Are the steel stoppers supplied individually?

The featured stopper listing supplies a set of two, made in Canada from steel. It lists the 1977–78 CB750K application and references 52136-405-000 and 52136-ME1-670. Verify the fitted stopper pattern and required quantity.

Can the primary chain set replace my rear-wheel chain?

No. The genuine Honda set contains two chains for the engine primary-drive system. It is distinct from both the cam chain and the chain between the front and rear wheel-drive sprockets. Choose by system and part location.
