Hydraulic System Spare Parts
Hydraulics are the muscle behind every excavator boom, loader lift, and dozer tilt — and when pressure drops or a cylinder starts weeping, production stops. Parts in this category rebuild and maintain that circuit end to end: main and pilot pumps, travel and swing motors, main control valves and spool valves, boom and bucket cylinders, plus the seal kits, o-rings, and hoses that fail long before the iron does.
Slow cycle times, drifting cylinders, and internal leakage past a worn spool are the usual reasons parts get pulled, and the right replacement has to match displacement, pressure rating, and port configuration exactly. 3GEN supplies 100% OEM hydraulic components for 40+ machine brands, all shipped free worldwide — to any country — with full tracking and duties paid. Send our specialists a serial number, OEM number, or hydraulic schematic and they will match the correct pump or valve against 3,300+ parts in stock and a cross-reference of 564,000+ part numbers.
