Danfoss Eaton Char-Lynn 104-3155-006 hydraulic motor Hydraulic Torque Motor0 M02119AC01AA0100010000000ABAAF

Product Overview

The 104-3155-006 geroler orbit hydraulic motor is a universal medium-heavy duty aftermarket replacement part for original Eaton Char-Lynn 104 series hydraulic drive assemblies, cross-compatible with Danfoss M02119AC01AA0100010000000ABAAAF equivalent hydraulic motors, widely applied on agricultural harvesting, medium construction trenching and wood processing hydraulic machinery.

It adopts mature integrated balanced disc valve geroler design, converting medium-high pressure hydraulic oil into smooth low-speed high-torque rotary power. All internal core transmission components are precision machined from high wear-resistant alloy, supported by double-sided heavy tapered roller bearings and multi-layer NBR integrated sealing structure. The whole motor strictly follows OEM engineering drawings for 4-bolt Magneto mounting flange, straight keyed drive shaft, staggered manifold main and drain port arrangement, realizing true plug-and-play replacement without pipeline reworking or bracket adjustment.

Thickened cast iron outer housing delivers superior anti-collision and anti-dust protection in crop harvesting and trenching field working conditions. The factory pre-installed built-in check valve effectively suppresses reverse hydraulic pressure surges during equipment shutdown, avoiding dangerous uncontrolled sudden rotation of auger bits and harvester reels and lifting overall operation safety. All finished motors pass comprehensive hydraulic bench testing to verify torque stability, rotation smoothness and zero-leakage performance under rated medium-heavy working pressure.

Key Features

✅ 1:1 Full OEM Interchangeability Direct drop-in replacement for Eaton Char-Lynn 104-3155-006 and Danfoss M02119AC01AA01, fully matched with original 4-bolt Magneto mounting flange, straight keyed shaft and staggered manifold port layout, no mechanical modification required.

✅ Balanced Disc Valve Geroler System High-precision alloy geroler gear set with balanced disc valve drive delivers uniform high torque output, low pulsation and smooth quiet variable-speed operation under medium-high flow pressure.

✅ Reinforced Thick Cast Iron Housing Robust thick cast iron shell provides outstanding resistance to impact, crop debris, mud and wide temperature fluctuations, perfectly suited for dusty harvesting and rugged trenching working environments.

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

✅ Dual Front & Rear Tapered Roller Heavy Bearings Dual tapered roller bearing assembly withstands large radial and axial impact loads, reduces internal friction loss and significantly extends motor service life under frequent start-stop heavy-duty cycles.

✅ Built-In Anti-Reverse Safety Check Valve Standard integrated one-way check valve prevents hydraulic backflow and uncontrolled machine runaway when hydraulic power cuts off, greatly improving operation safety for harvester and trencher operators.

✅ Complete Factory Hydraulic Quality Inspection Every finished unit undergoes full flow, working pressure and leakage bench testing before delivery to screen defective products and ensure consistent stable medium-heavy load performance.
