Product Overview
The MSE05-2-133-R05-1220-EJ00 is a large-displacement radial piston hydraulic motor from Poclain Hydraulics’ MS/MSE05 series, featuring a displacement of 750 cc/rev, belonging to the MSE05 series (E-version, 400 bar maximum working pressure). This model has manufacturer part number A01847H and weighs approximately 41 kg. The MS/MSE05 series is the mid-frame offering in Poclain’s multi-purpose motor line, covering displacements from 260 to 750 cc/rev with up to 50 kW (67 HP) power, 4,770 N·m (3,518 lb-ft) maximum torque, 450 bar maximum working pressure for MS version and 400 bar for MSE version, with a multi-speed concept reaching up to 700 rpm.
The MS/MSE05 series is built on a tried and tested radial piston cam design that is continually being improved, delivering high efficiency at any speed or operating pressure, making a major contribution to machine energy efficiency. The motor features low noise, high radial load capacity and high starting torque, with a multi-piston cam ring structure. Hydrostatic dynamic braking is an inherent design feature. The MS05 series employs imported bearings and oil seals, modular design, and smooth running even at very low speeds, with permissible radial and axial loads and multi-disc brake availability.
The model code breaks down as follows: MSE05 identifies the MS/MSE series 05 frame size (E-version, 400 bar maximum working pressure); 2 denotes displacement group 2 (750 cc/rev configuration); 133 is the flow-distribution/function module code; R05 is the shaft and mounting configuration code (wheel flange mounting, 10×Ø18 on Ø140); 1220 is the mounting flange and output-end code; EJ00 denotes additional options.
Every MSE05-2-133-R05-1220-EJ00 unit undergoes 100% simulated operating-condition bench testing prior to shipment, covering pressure cycling, speed stepping and volumetric efficiency verification. Mounting flange, shaft end and port dimensions match the original Poclain MSE05 series exactly, enabling true drop-in interchangeability with zero modification required.

Key Technical Advantages
1. Internal Curve Radial Piston Design for High Startup Torque and Smooth Low-Speed Operation
The MSE05-2-133 employs Poclain’s patented internal curve radial piston design, with multiple pistons arranged radially around a cam ring to deliver high torque at extremely low speeds. With theoretical torque of 1,193 N·m at 10 MPa and maximum torque of 4,770 N·m at full displacement, the motor operates smoothly across the 0–265 rpm speed range without stick-slip. High startup torque ensures reliable starting under load, making it ideal for wheel-drive and tool drive applications requiring high startup torque.
2. Modular Architecture with TwinLock™ Anti-Skid System
The MS/MSE05 series employs Poclain’s modular design concept, allowing displacement group, flow-distribution module, brake module and output-end module to be reconfigured, with the modular design easing use on all demanding applications for the most demandable market as construction equipment, material handling, agricultural, environment, mining, on rail, marine and industry. The wheel flange mounting configuration (10×Ø18 on Ø140) supports wheel-drive mounting for skid steer loaders, harvesters, forklifts and more. Optional TwinLock™ integrated anti-skid provides differential locking via hydraulic control for improved traction on challenging terrain.
3. High-Precision Cam Ring and High Radial Load Capacity
The MSE05-2-133 cam ring is manufactured from high-hardness alloy steel with precision grinding to resist high-frequency contact fatigue from piston rollers. A hydrodynamic oil film forms between rollers and cam ring, significantly reducing wear rate and extending overhaul intervals. The motor features high radial stress design, enabling direct handling of wheel or tool-end radial loads without additional bearing support mechanisms, simplifying drivetrain design. The modular design allows replacement of individual worn modules rather than the entire motor, substantially reducing total cost of ownership.
4. Low Noise Design and High Starting Torque
MS series motors are renowned for low noise output, with the coordinated action of multiple pistons and the cam ring effectively reducing operating noise and torque pulsation. The high starting torque characteristic combined with 4,770 N·m maximum torque ensures reliable starting and stable operation under load. The MS05 series maintains high volumetric and mechanical efficiency at 50 kW maximum power and 450 bar maximum pressure, making a major contribution to machine energy efficiency.
5. 100% Simulated Load Testing & Drop-In Interchangeability
Each MSE05-2-133-R05-1220-EJ00 unit is bench-tested under simulated operating conditions prior to dispatch, covering pressure cycling, speed shifting and thermal variation. Mounting flange, shaft end and port dimensions match the original Poclain MSE05 series exactly, enabling direct replacement without pipework or interface modification. Both complete motors and spare parts are 100% interchangeable.

Expert Maintenance Tips
1. Oil Cleanliness and Temperature Control: Maintain system oil cleanliness at ISO 4406 18/16/13 or better. HV46 hydraulic oil is recommended. Operating oil temperature should be kept below 80°C; elevated temperatures accelerate seal degradation. Replace hydraulic oil and filter after the first 500 hours, then follow a 2,000-hour or annual replacement cycle. Case drain temperature is affected by pressure and speed and is always higher than circuit temperature—system temperature must not exceed 115°C at any point.
2. Drain Line Management and Housing Priming: The drain port must return to the reservoir independently—housing back pressure must not exceed 2 bar. The drain line end must remain submerged to prevent air ingestion. Fill the housing with clean hydraulic oil before first startup. After extended shutdown, fill the housing again before restarting.
3. Wheel Flange Mounting Surface Inspection: The MSE05-2-133-R05-1220-EJ00 features wheel flange mounting (10×Ø18 on Ø140). Periodically inspect the output flange plane and wheel hub mating surface for wear or deformation. Ensure flange mating surface parallelism deviation does not exceed 0.05 mm during installation, and tighten bolts evenly in a diagonal sequence to Poclain technical manual torque values. Mounting surface flatness requirement is 0.2 mm with Ra 12.5 μm surface roughness.
4. Periodic Piston Group and Cam Ring Inspection: As a radial piston motor, the MSE05-2-133’s primary wear points are the piston rollers and cam ring contact surface. Inspect piston roller wear and cam ring working surface every 2,000 hours. Abnormal noise or efficiency loss requires immediate shutdown and service. Use Poclain original specification parts when replacing piston groups to ensure fit accuracy and assembly torque per technical manual requirements.
5. Modular Repair Strategy: The MS/MSE05 series modular design allows replacement of individual worn modules rather than the entire motor. Establish a modular spare parts inventory including flow-distribution module seals, piston groups and cam rings to minimize machine downtime. When replacing modules, follow Poclain official technical manual torque values and assembly sequences.
