Description
Wärtsilä 121 1003 is listed as VALVE ROTATOR TRW in the supplied Wärtsilä 9L26 main-engine spare-parts documentation. The rotator forms part of the exhaust valve spring arrangement and promotes incremental valve rotation during operation, helping distribute thermal loading and wear around the valve face and seat. Dimensions and spring interfaces depend on the original valve configuration. The source specifies 18 pieces per engine and 36 pieces for two engines. Verify the mating valve, spring and retainer before installation.
