Description

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

    Applications
  • Construction Machinery:Excavators, skid steer loaders, backhoe loaders, road rollers, and compact construction equipment.

  • Agricultural Equipment:Tractors, harvesters, sprayers, hay balers, agricultural winches, and general farm machinery.

  • Material Handling:Forklifts, belt conveyors, lift tables, sweepers, and aerial work platforms.

  • Industrial Machinery:Hydraulic winches, drilling rigs, hydraulic power units, industrial automation systems, and conveyor systems.

  • Mobile Equipment:Refuse trucks, snow plows, utility vehicles, and marine hydraulic systems.
