MK04-2-114-K04-3340-3000 Poclain MK Motor

Product Overview

The MK04-2-114-K04-3340-3000 and related models (MK04, MK18, MKE18, MK35, MK47) belong to the Poclain Hydraulics MK series of high-pressure radial piston motors (cam-lobe design). Designed for direct drive applications, these motors deliver high torque at low speeds, ideal for wheel motors on road rollers. Fully interchangeable with original Poclain interfaces and performance (100% match), every unit undergoes 100% simulated operating condition testing. Ideal for mobile equipment, the series features precision radial piston technology, high starting torque, compact design and optional parking brake.

Key Technical Advantages

1. Precision cam and radial piston design delivers high starting torque and smooth low-speed operation with excellent volumetric efficiency.
2. Compact high-torque density: Direct-drive design reduces intermediate transmissions, saving space and weight.
3. Long-life bearings and high reliability: Supports high pressure and vibration for continuous roller operation.
4. 100% simulated duty testing and full interchangeability: Exact match to original Poclain interfaces and performance curves—true drop-in replacement with no modifications.
5. Flexible options and integrated braking: Optional parking brake and multiple flange configurations for diverse machinery.

Application Areas

Wheel drives on road rollers, travel drives in construction machinery, agricultural equipment, mining machinery, environmental machines and applications requiring high-torque low-speed direct drive.

Expert Maintenance Tips

Ensure the housing is correctly filled with oil through the drain port before start-up to prevent dry-running damage. Use hydraulic fluid meeting recommended viscosity and cleanliness levels. Periodically inspect seals, brake and bearings; perform moderate-load break-in initially. Strictly observe maximum pressure and speed limits. When replacing, verify the complete model code (including brake and flange options) for full interchangeability. Refer to official Poclain MK technical manuals for precise torque-speed curves.
