The 124-link A and 82-link B products are separate chains, both carrying the stated 412H designation. Confirm the engine position before ordering and follow the correct Honda timing procedure during the work. Neither is simply an alternative length for the same position.
The smaller B tensioner has a separate spring, reference 14538-425-000. The larger A tensioner spring uses 14514-425-010. Compare the retained assembly and inspect guides and related components so the repair scope is established before parts are selected.
No. The A and B chains are separate products with different link counts. Identify which position requires service and select the corresponding chain or both deliberately.
The B-tensioner spring replaces 14538-425-000. Compare the retained tensioner and engine diagram before selecting it; the larger A assembly uses a different spring reference.
Inspect the associated assembly first. Chain, tensioner and guide condition inform the repair, and replacing one component may leave another worn part in the timing system.
