1981 Honda CB750K Cam Chains, Guides & Tensioners

The 1981 Honda CB750K cam-drive listings distinguish silent chain A from chain B and offer separate guides and tensioners. Start by identifying the component being replaced. Similar names do not establish that a chain, tensioner, spring or joining link is interchangeable.

Identify chain A, chain B and the matching component

Chain A is listed as 412H with 124 links, while chain B is listed as 412H with 82 links. Keep their identities separate and compare each replacement reference with the inspected component.

Use the chain designation before the length

The two featured chains share the 412H designation but have different named positions and link counts. The A listing gives 124 links; B gives 82. Record which chain is being serviced, then compare its replacement reference and specification rather than choosing whichever length appears close.

Order guides and tensioners as individual choices

The guide and two tensioner listings describe separate components, rather than an all-in-one cam-drive repair package. Compare their references and photographs with the dismantled parts. For a joining link, confirm exact compatibility and the relevant installation guidance before combining it with either featured chain.

Common questions

Are the A and B cam chains the same product?

No. Chain A is listed as 412H with 124 links, while chain B is 412H with 82 links and different replacement references. Identify the chain position on the engine before choosing; a shared chain-type label does not make the lengths interchangeable.

Does a cam chain purchase include a guide or tensioner?

The featured products are separate chain listings, and the guide and tensioners have their own listings. Do not treat the chain as a complete repair kit. Read each product’s contents and add only the separately identified components the repair requires.

Can the listed silent-chain rivet link be assumed to fit?

The rivet-link listing uses a chain-type designation that differs from the 412H designation on these chains. Exact compatibility is not established here. Ask for confirmation using both product links before selecting the link or planning an installation around it.
