SEAT - VALVE SPRING-OUTER (Komatsu KO8772236)

A worn valve spring outer seat can lead to reduced valve sealing pressure and eventual cylinder misfire. This aftermarket replacement part references Komatsu as the OE maker and carries the cross-reference number KO8772236. The seat provides a stable mounting surface for the outer valve spring, ensuring consistent spring force during operation. Over time, a degraded seat may allow the spring to shift, causing uneven valve motion and potential loss of compression. The item ships at approximately 0.007 pounds.
