1981 Honda CB400TB Drive-Chain Adjusters

Damaged rear-wheel adjusters can make a routine chain adjustment difficult. This 1981 Hawk selection offers an adjuster with its nut and bolt. Inspect both sides of the fitted swingarm, then order for the positions that need replacement rather than assuming a paired kit.

1981 Honda CB400TB · Chain Adjusters Buying guide

Count the adjuster positions that need new hardware

The featured item is one rear drive-chain adjuster assembly. Compare its plate and bolt arrangement with the motorcycle, particularly if a previous owner fitted a different swingarm or rear wheel.

Parts to consider

Honda CB Drive Chain Adjuster with Nut & Bolt ~ Replaces 40543-471-000 / 40543-312-010 Rear drive-chain adjusterOne adjuster supplied with its nut and bolt. Order the number of adjuster positions being renewed.View part

Plan the quantity by side

Each purchase provides an adjuster, nut and bolt. Two purchases are needed when renewing both positions. Check the remaining axle hardware at the same time so that a missing or damaged surrounding part does not leave the repair unfinished.

Finish with a complete drive inspection

New adjusters do not restore a worn chain or sprocket. Check the rear drive components before setting wheel alignment and chain slack, then follow the Honda service procedure. Modified swingarms require direct comparison of the adjuster arrangement before relying on model-specific application.

Buying questions

Is this a left-and-right pair?

No. The supplied parts make one adjuster unit with its nut and bolt. Order two units if both positions need replacement, or one when inspection confirms the other side remains serviceable.

What should I check on a modified swingarm?

Compare the adjuster plate, axle opening and bolt arrangement with the installed hardware. A replacement swingarm may use another design even when the frame is a 1981 CB400TB.

Should a worn chain be replaced with the adjuster?

Assess the chain and sprockets independently. The adjuster positions the rear wheel; it does not repair worn chain joints or teeth. The inspection determines whether those parts also belong in the repair order.

Not sure which part you need?

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