Danfoss Eaton Char-Lynn 158-2944-001 hydraulic motor Hydraulic Torque Motor0 MT0049MA39AF0200000000000AA00A

Product Overview

The 158-2944-001 geroler orbit hydraulic motor is a universal heavy-duty aftermarket replacement unit for original Eaton Char-Lynn 158 series hydraulic drive assemblies, cross-compatible with Danfoss MT0049MA39AF020000000000AA00A equivalent hydraulic motors, widely applied on heavy intermittent-load hydraulic machinery including skid steer loaders and winter snow removal attachments.

It adopts mature integrated balanced geroler disc valve design, which converts high-pressure hydraulic oil into smooth ultra-high low-speed torque rotary power. All internal core transmission parts are precision machined from high wear-resistant alloy, supported by double-sided heavy tapered roller bearings and multi-layer NBR integrated sealing structure. The entire motor strictly follows OEM engineering drawings for bearingless 4-bolt square pilot mounting flange, spline drive shaft, staggered main and case flow SAE O-ring port arrangement, realizing true plug-and-play replacement without pipeline reworking or bracket adjustment.

Extra thickened cast iron outer housing offers superior anti-collision, anti-freeze and anti-corrosion protection in low-temperature snow removal and muddy farm heavy-duty working conditions. The factory pre-installed built-in check valve with leakage orifice eliminates the need for an independent case drain port, simplifying vehicle hydraulic pipeline layout while effectively suppressing reverse hydraulic pressure surges when equipment shuts down, preventing uncontrolled sudden rotation and lifting overall operation safety. All finished motors pass complete hydraulic bench testing to verify torque stability, rotation smoothness and zero-leakage performance under rated max intermittent working pressure.

Key Features

✅ 1:1 Full OEM Interchangeability Direct drop-in replacement for Eaton Char-Lynn 158-2944-001 and Danfoss MT0049MA39AF02, fully consistent with original bearingless 4-bolt pilot mounting flange, spline drive shaft and staggered SAE O-ring oil port layout, no machining modification required.

✅ Precision Balanced Geroler Disc Valve System High-precision alloy geroler gear set matched with balanced disc valve delivers even ultra-high torque output, low pulsation and smooth quiet variable-speed operation under high flow conditions.

✅ Extra Thick Reinforced Cast Iron Housing Robust thick cast iron shell provides outstanding resistance to impact, mud, ice, dust and wide temperature swings, perfectly suited for harsh cold winter snow removal and heavy construction field environments.

✅ Integrated Full Anti-Leak Sealing Package Heat-resistant standard NBR shaft seal + external dust seal dual sealing structure blocks internal & external oil seepage, maintaining steady output pressure under continuous max intermittent heavy load running.

✅ Dual Front & Rear Tapered Roller Heavy Bearings Dual heavy tapered roller bearing structure bears extreme radial and axial loads, reduces internal friction loss and greatly prolongs the whole motor service lifespan under frequent heavy impact work cycles.

✅ Built-In Anti-Reverse Safety Check Valve Standard integrated one-way check valve with leakage orifice cancels separate case drain pipeline, stops hydraulic backflow and unexpected machine runaway during power cut-off, significantly boosting skid steer & snow equipment operation safety for operators.

✅ Complete Factory Hydraulic Quality Inspection Each finished unit passes full flow, working pressure and leakage bench testing before shipment to filter defective goods and ensure consistent stable heavy-load performance.
