Frequently Asked Questions

What is included in the Honda 40543-392-000 drive-chain adjuster set?

The complete set includes two adjusters, two adjusting bolts and two nuts—enough for both sides of one rear wheel on the listed 1975-1978 CB750F, CB750K and CB750A applications.

How should the rear wheel be aligned after installing chain adjusters?

Use both adjusters evenly, verify rear-wheel alignment with an accurate method and set chain slack to the Honda specification. Do not rely only on worn or mismatched swingarm index marks.

What else should be inspected during chain adjustment?

Check the drive chain, front and rear sprockets, axle, wheel bearings and adjuster seating. Tighten the axle and adjuster hardware to the service-manual procedure, then recheck slack after the axle is secured.
