1981 Honda CB900F Cam Chains & Tensioners

The 1981 CB900F cam drive uses distinct A and B service listings: a 126-link chain A and an 82-link chain B, plus position-specific tensioners, springs and a guide. Identify the worn component before choosing parts; similar names do not make the two positions interchangeable.

1981 Honda CB900F Supersport · Camshaft Drive Buying guide

Keep A and B timing parts distinct

The CB900F cam drive has separate A and B chain listings, guides and tensioners. Diagnose the source of noise before ordering: a new spring or tensioner cannot correct every worn chain, damaged guide or timing fault.

Choose by position and reference

The two chains differ in length, and the smaller B tensioner has a separate identity from the main tensioner. Compare the old component and the service-manual diagram before ordering. A spring named B belongs to the smaller B tensioner; the A spring is for the larger main unit.

Do not pair these chains with an unmatched rivet link

The featured chains are specified as 412H. The separate 82RH2015 rivet-link listing expressly excludes 412H compatibility. Do not combine them merely because both appear among cam-drive parts; any joining link and installation method must be approved for the exact chain.

Buying questions

Will a new tensioner cure every cam-chain rattle?

No. Inspect chain wear, guide surfaces and tensioner movement and confirm cam timing. The CB900F manual specifies cold-engine cam-chain tension adjustment; use its complete procedure rather than treating noise as proof that one tensioner has failed.

Can the 82RH2015 rivet link join the listed 412H chains?

No. Its listing specifically excludes 412H. Both chain series and construction must match the joining link approved by the chain manufacturer. A shared category or similar-looking silent chain is not evidence of compatibility.

How do I avoid mixing the two tensioner positions?

Match the removed component and Honda diagram. The larger main unit uses 14500-series references and spring A; the smaller B unit uses 14530-series references and spring B, 14538-425-000. Keep those assemblies and their springs separate.
