Product Overview
158-3990-001 belongs to Eaton Char-Lynn/Danfoss 158 series medium-duty low-speed high-torque geroler orbit hydraulic motor, our aftermarket replacement strictly copies original OEM structural and performance standard for universal repair replacement.
Adopting mature roller geroler rotor-stator + precision disc distribution valve technology, this hydraulic motor features outstanding anti-overload and anti-stall capability, capable of steady high torque output under low rotating speed. All installation specifications fully consistent with original drawing to avoid secondary machining during equipment overhaul. It’s extensively used for medium-size harvesters, large lawn cutters, skid steer auger drives, small road sweepers and various industrial auxiliary hydraulic drive systems.
Key Features
✅ 100% OEM Drop-in Compatibility: Identical mounting, shaft, port dimension as original 158-3990-001 for no-mod installation
✅ High-efficiency Roller Geroler & Disc Valve Core: Stable torque output, small flow pulsation and high volumetric efficiency
✅ Thickened Cast Iron Housing: High-strength cast iron shell resists impact, mud and harsh field working environment
✅ Premium Sealing Option: Standard NBR nitrile seals, optional FKM high-temperature seal for extreme heat working condition
✅ Heavy-duty Dual Bearing Configuration: Strong radial & axial load resistance to extend whole service lifespan
✅ Economical Aftermarket Alternative: Same OEM-grade performance with much more competitive cost vs original brand spare parts
✅ Full Factory Hydraulic Pre-test: All motors complete pressure, flow and leakage test before outbound delivery
