103-1004-012 | 103-1004 Hydraulic Motor | Direct Replacement for Eaton Char-Lynn S Series | Cast Iron High Torque | Displacement 160cc/r | Maximum Pressure 138BAR | 4-Hole Flange |
【Precise Matching · Upgraded and Reinforced】 Original Part Number: 103-1004-012 | 103-1004. This motor is a direct replacement for the Eaton Char-Lynn S series. ⚠️Note: Unlike the original motor, we have added an extra reinforcing bolt in the middle to improve structural strength. This unique optimized design enhances overall stability during high-speed, heavy-load operation, effectively reduces vibration, improves operational safety, and does not affect the original motor's mounting dimensions, assembly compatibility, or daily use.
【Stable Output Performance】Suitable for various applications:Displacement (m³): 160; Maximum working pressure (BAR): 138; Recommended flow rate (LPM): 53; Maximum speed (RPM): 374; Maximum torque (N.m): 297; Output shaft: Straight shaft; Mounting flange: 4-hole flange; Rotation direction: Clockwise.Utilizing an advanced gear design, it achieves stable high torque output at low speeds, effectively avoiding power decay and stalling during heavy-load operation.
【High Volumetric Efficiency & Anti-Heat Degradation Design】Equipped with an advanced gear ring structure, it boasts a volumetric efficiency of up to 96%, resulting in extremely low energy loss. Even under continuous high-load conditions (such as zero-turn lawnmowers and snowplows), it maintains stable torque and controllable temperature rise, preventing power decay or seal failure due to overheating, significantly reducing equipment downtime.
【Leak-Free Design & All-Weather Durability】 The housing is made of precision cast iron in one piece, with a black anti-rust paint coating for corrosion resistance and impact resistance. SAE O-ring seals with dust caps are standard at the inlet and outlet, completely eliminating external leakage. Each motor undergoes 100% pressure testing before leaving the factory to ensure leak-free operation under harsh conditions.
【Professional Installation Guide (Must Read)】⚠️ Before installation, please verify that your equipment part number matches this motor. If in doubt, please send us your model number or original factory code, and we will confirm it for you. Before connecting the new motor, thoroughly flush the hydraulic lines to remove impurities or water from the old oil. Apply clean hydraulic oil to the O-rings; tighten the connections and then lock them to the manufacturer's specified torque. It is strongly recommended to replace the hydraulic oil filter and fluid simultaneously, which can extend motor life by more than 30%.
