1983 Honda CB750SC Cam Chains & Tensioners

Identify the worn cam-drive position before selecting parts for the 1983 CB750SC. The A and B chains differ in length, and the tensioner choices are also distinct. Build the order from the engine diagram and inspection rather than assuming all DOHC cam-drive pieces interchange.

1983 Honda CB750SC · Cam Chains & Tensioners Buying guide

Identify chain and tensioner positions before purchase

The listed A chain is 412H × 124 links; B is 412H × 82. The smaller B tensioner is separate from the genuine Honda larger tensioner choice, so keep their references tied to the correct positions.

Keep the two chain specifications distinct

A and B identify separate cam-drive chains, not simply different brands of the same replacement. Match the 124-link or 82-link specification to its location. If the engine has been exchanged, identify that engine before using the frame’s model year to build the order.

Include the supporting parts in the inspection

Worn guides, springs and tensioners need their own assessment alongside the chains. The smaller B tensioner is linked separately here. Cam timing work should follow the exact service procedure, and a rivet-link choice requires confirmation against the actual chain specification.

Cam Chains & Tensioners questions

How long are the two cam chains?

The A product is specified as 412H × 124 links and B as 412H × 82 links. Match each to its intended position in the engine diagram before ordering.

Does one tensioner suit both positions?

The catalog distinguishes the smaller B tensioner from the main tensioner. Compare the position and part reference; the shared engine application does not establish that the two pieces interchange.

Will a chain order include guides and springs?

The chain products describe the chains themselves. Guides, springs and tensioners are separately listed, so inspect them and confirm each required component before completing the service order.
