SPONGE (Komatsu KO37B-1CV-2151)

KO37B-1CV-2151: A worn sponge can allow debris to bypass the intended barrier, leading to contamination of sensitive components. The Komatsu catalog reference KO37B-1CV-2151 identifies this aftermarket replacement part. This sponge serves as a compressible seal or filter element, providing a physical barrier against particles and moisture. Its plain mechanical function is to block or absorb unwanted material in a designated cavity. A common failure consequence is that a degraded sponge loses its sealing ability, permitting ingress of dirt or fluid. Verify the serial number or application, then call (562) 693-7748. This part is listed as a sponge, a generic type-level component used for cushioning or filtration.
