Keep A and B timing components distinct

Cam chain A is listed as 412H × 124 links; chain B is 412H × 82 links. The smaller B tensioner is a separate component, not a substitute for the main tensioner.

Two chains, different jobs

The featured A and B chains share the 412H designation but have different link counts. Keep their packaging and assembly positions distinct throughout the repair. A broad DOHC CB750 application does not make the two chain products interchangeable.

Tensioner parts are separate

The B tensioner is explicitly the smaller tensioner. Its spring differs from the spring for the larger main A tensioner. Match the actual component and reference, then follow the appropriate manual rather than improvising a timing procedure.

Camshaft Drive Parts questions

Are chains A and B the same length?

No. The A chain is listed as 124 links and the B chain as 82 links. Select by the chain designation and its position in the DOHC timing system.

Does a tensioner include its matching spring?

Separate springs are listed for the larger A and smaller B tensioners. Check the selected product’s contents and the condition of the existing spring before assuming a complete assembly.

Which spring belongs with tensioner B?

Choose the spring specifically identified for the smaller B tensioner. The larger main A tensioner has a separately listed spring; compare the original assembly and reference before ordering.
