Write down A or B alongside the chain reference and link count. The two featured chains share a 412H description but have different lengths. That shared description does not make them interchangeable, and neither listing describes the external chain driving the rear wheel.
Check the appropriate tensioner, spring and guide while planning timing-drive repairs. The B tensioner is identified as the smaller assembly, and its spring is a separate item. Use the service procedure for inspection and installation rather than treating a new chain as a complete timing-system rebuild.
The A chain is listed as 412H with 124 links, while B is 412H with 82 links. Choose the correct position and reference from the DOHC timing-drive arrangement.
The separate spring B listing explicitly describes the spring for the smaller B tensioner. The A spring belongs to the larger tensioner, so compare the assembly identification before ordering.
The chains, tensioners, springs and guide have separate listings. Check each description and inspect the supporting parts, then add only the components required by the measured condition and repair plan.
