Product Description
Premium factory-direct HZ-74318-DCE Fixed Displacement Axial Piston Motor, precision-engineered as a 100% direct drop-in replacement for OEM Eaton / Char-Lynn 74318-DCE (74318 / 74315 Series). Built to heavy-duty industrial and mobile mounting specifications, this compact swashplate piston motor delivers dynamic startup torque, exceptional volumetric stability, and low-noise rotation under continuous operation. Ideal for agricultural combine harvesters, turf maintenance equipment, hydraulic winches, and auxiliary mobile drives, our HZ-74318-DCE motor reliably operates at continuous pressures up to 210 bar with intermittent peak shocks up to 250 bar .

FAQ
Q1: Will your HZ-74318-DCE motor replace our original Eaton 74318-DCE directly without changing port fittings or shaft couplings? A: Yes, 100%. The ‘DCE’ suffix specifies exact mounting bolt patterns, shaft splines/keys, and fluid port locations. Our HZ-74318-DCE is built strictly from factory blueprints to ensure an absolute 1:1 drop-in replacement with zero hydraulic line or mechanical mounting modifications.
Q2: Piston motors on mobile sweepers and harvesters suffer from RPM loss under high pressure. How does Haozheng maintain stable output speed? A: Output speed drop under load is caused by internal fluid slippage between the cylinder block and valve plate. At Guangdong Haozheng, our cylinder barrels and valve plates undergo automated micro-honing and vacuum-sintering processes to ensure tight dynamic oil sealing. Every motor is 100% load-tested on our digital test benches to verify volumetric efficiency before packing.
