The Royal Enfield 573918/B Auto Chain Tensioner Assembly Black is an OEM replacement component designed for compatible Royal Enfield UCE engine applications.

Royal Enfield parts data identifies 573918/B as “AUTO CHAIN TENSIONER ASSY BLACK.” The earlier 573918/Ais listed as “AUTO CHAIN TENSIONER,” while 573918/B is the black-finish assembly version.

The automatic chain tensioner maintains appropriate tension in the engine’s chain drive, helping reduce excessive chain slack, noise and unwanted movement. A worn or faulty tensioner can contribute to chain noise and incorrect chain tension.

This assembly is intended as a direct OEM-style replacement where 573918/B is specified. Always match the complete part number before ordering.
