1981 Honda CB750K Drive Chain Adjuster Hardware

The rear-wheel choices here are the chain adjuster set and its separate stopper set. Compare both packages with the hardware on your 1981 Honda CB750K. The primary-chain listing also appearing in this category should not be treated as a rear-wheel chain.

1981 Honda CB750K · Drive Chain & Adjusters Buying guide

Replace the correct pieces of the adjustment hardware

The adjuster package supplies two adjusters with bolts and nuts. The stopper package supplies two separate stoppers. Use the removed hardware to decide which package or combination the repair needs.

Parts to consider

1979-83 Honda CB750 / CB650 Drive Chain Adjuster Set ~ Replaces 40543-425-000 Chain adjuster, bolt and nut setIncludes two chain adjusters, two adjusting bolts and two nuts. The listed adjuster replacement reference is 40543-425-000.View part

Compare the complete hardware arrangement

Inspect the adjusters, their bolts and nuts, and the stoppers as separate pieces. The two packages have different inventories. Photograph the assembled adjustment hardware before placing the order so the contents can be compared with both sides of the motorcycle, including any missing pieces.

Identify a wheel chain separately

The chain product shown alongside these adjusters is explicitly titled a primary chain, with its own replacement reference. For a wheel drive chain, provide the installed chain and sprocket details so that requirement can be reviewed separately from the adjustment hardware.

Common questions

Are adjusters and stoppers supplied in one package?

The featured adjuster set lists two adjusters, two bolts and two nuts. The stopper set is a separate product containing two stoppers. Compare those inventories with the parts on the motorcycle before deciding whether both packages are needed.

Can I order just one adjuster from the featured set?

The featured listing describes a pair of adjusters with two adjusting bolts and two nuts. It is a set rather than an individual adjuster listing. Review that package quantity against the parts required for your repair.

Is the primary-chain listing the rear-wheel drive chain?

The product is specifically described as a primary chain. Keep it separate from a wheel drive chain requirement when planning the order. Ask for help identifying a wheel-chain option using the installed chain and sprocket details.

Not sure which part you need?

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