One New Aftermarket Replacement Hydraulic Cylinder Assembly for Caterpillar (Cat) Excavators
This aftermarket replacement hydraulic cylinder assembly (replaces Caterpillar part number 1709938 / 170-9938) is a direct-fit cylinder for the hydraulic system on a wide range of Caterpillar (Cat) mid-size excavators. Hydraulic cylinders on these machines control boom, stick, and bucket movement, and a failed or leaking cylinder assembly requires prompt replacement to restore full digging force and cycle speed. Verify your specific machine model and serial number prefix before ordering to confirm correct fitment.
