1978 Honda CB400TII Hawk II Drive-Chain Adjusters

Rear-wheel positioning depends on sound adjustment hardware as well as the chain itself. Compare the Hawk II’s existing adjuster and swingarm arrangement with the replacement, then decide which positions need service before ordering the adjuster, nut and bolt combination.

1978 Honda CB400TII Hawk II · Chain Adjusters Buying guide

Match the adjuster to the rear-wheel assembly

This replacement is an individual rear drive-chain adjuster with its nut and bolt. It is useful when the fitted hardware is bent, corroded or damaged during rear-wheel service.

Parts to consider

Honda CB Drive Chain Adjuster with Nut & Bolt ~ Replaces 40543-471-000 / 40543-312-010 Rear drive-chain adjusterOne drive-chain adjuster with nut and bolt for the listed Hawk II application. Match the installed swingarm arrangement and order each required position.View part

Check the surrounding hardware

An adjuster works with the axle and swingarm, so inspect those areas while the rear wheel is being serviced. A damaged mounting point or incorrect axle arrangement needs attention before adjustment. Replacement hardware should match the parts fitted to the motorcycle.

Set alignment after the repair

Once the correct hardware is fitted, use the Honda manual for chain adjustment and rear-wheel alignment. Replacing a bent adjuster does not by itself establish correct chain slack, and adjustment cannot restore a worn chain or sprocket.

Common questions

Does one order supply a pair of adjusters?

The product is one adjuster with nut and bolt. Inspect the positions on the motorcycle and order the number of complete adjuster assemblies required, rather than treating the item as a pair.

Will it fit a replacement swingarm?

Check the replacement swingarm’s adjuster shape, mounting arrangement and axle hardware first. The Hawk II model application describes the listed stock-type fitment, not every swingarm conversion.

Should I replace the adjuster when the chain needs adjustment?

Not automatically. Inspect the adjuster and its threads for damage, and check chain and sprocket wear. Serviceable hardware can still be used to make the manual-specified adjustment.

Not sure which part you need?

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