Product questions
What is Yanmar 119574-11880 and where is it listed?
Part 119574-11880 is listed as a seat, valve in a cylinder-head parts diagram. It is also described as an injector seating washer. It is not an operator seat; verify the part number and intended position before ordering.
Will 119574-11880 fit my Yanmar 6LYA-STP engine?
A 6LYA-STP cylinder-head parts list includes 119574-11880, but also lists a different nozzle seat. The correct choice depends on the engine configuration. Provide the engine model and serial number and, if possible, the existing seat or nozzle details for verification.
Is 119574-11880 interchangeable with nozzle seat 119625-11880?
Do not assume they are interchangeable. A 6LYA-STP parts diagram lists them as separate items, and a technical discussion describes a case where 119574-11880 had an opening too small for the nozzle protector. Confirm the correct seat against the engine serial number and nozzle configuration.
