803070608 XGYG01-153B Left Boom Cylinder for XCMG Loader – Genuine Spare Part

803070608 XGYG01-153B Left Boom Cylinder — XCMG Loader Working Device Hydraulic Cylinder

The left boom cylinder (Part No. 803070608 / Drawing No. XGYG01-153B) is the core lift actuator in the working hydraulic system of XCMG wheel loaders. Installed between the frame and the boom, it converts hydraulic pressure into linear mechanical force to drive boom lifting and lowering, working in tandem with the tilt cylinder to complete the full loading-lifting-dumping cycle .

As a member of XCMG's XGYG01 cylinder family, this left boom cylinder is engineered to XCMG's original design specifications. The XGYG01 series covers multiple cylinder types within the loader working hydraulic system — boom cylinders, tilt cylinders, steering cylinders — and must be carefully distinguished when ordering . This part (803070608 / XGYG01-153B) is specifically the left-side boom lift cylinder.
