MHM75C878BEOL2511MG042 Hydraulic Gear Motor Replacement For Mobile Construction Equipment

Hydraulic Gear  Motor Introduction

Model MHM75C878BEOL2511MG042 is heavy-duty ductile cast iron external hydraulic gear motor of MHM75 series, specially designed for drive systems of mobile construction machinery. The prefix MHM stands for hydraulic gear motor, different from MHP gear pump, they cannot be interchanged. It adopts three-piece integrated ductile iron housing, fully identical SAE mounting flange, port size, output shaft, rotation direction and seal layout as original MHM75 motor. Direct replacement without pipeline modification, widely used in dump semi-trailers, road sweepers, agricultural harvesters and auxiliary drive units of light construction equipment.

Normally, it is packaged in cardboard boxes and then shipped on pallets or wooden crates. 

Hydraulic Gear Motor Advantages

• Rugged Ductile Cast Iron Housing
  
  
  Integral casting structure with excellent shock resistance and pressure resistance, stable under rated 210bar continuous pressure and max 240bar intermittent peak pressure. Hard to deform or leak under harsh construction and transportation conditions, much longer service life than aluminum gear motors.
• High Precision Wear-resistant Internal Parts
  
  
  Quenched alloy steel spur gears with balanced floating thrust plates to minimize internal leakage, volumetric efficiency keeps over 88%. Low-friction bush bearings bear heavy radial loads, wide speed range 500-3000rpm, fast response for frequent start-stop and forward-reverse switch, low operation noise.
• Good Anti-pollution & Low Maintenance Cost
  
  
  External gear structure tolerates minor impurities in hydraulic oil, less stuck failure for field machinery, no frequent filter replacement required. Simple internal structure for easy disassembly and repair, ideal bulk stock for overseas hydraulic repair shops.
• Universal Standard Installation
  
  
  Standard SAE flange, inlet/outlet ports and spline output shaft. Suffix MG042 defines exclusive seal kit, rotation direction and drain port layout. Customization available for different displacements, port types and shaft forms within MHM75 series.
• Wide Fluid Compatibility & Reliable Warranty
  
  
  Compatible with mineral hydraulic oil and water-glycol fire-resistant fluid, stable operation under high & low outdoor temperature. Every motor passes strict factory test on torque, pressure and leakage, standard 12-month warranty, extended warranty for bulk orders.
