MCR3 MCR03 Hydraulic Motor | Rexroth & Caterpillar

MCR3 MCR03 Hydraulic Motor

The MCR3 MCR03 hydraulic motor is a radial piston hydraulic motor designed for low-speed, high-torque hydraulic drive applications. SEIMT supplies complete aftermarket MCR3 / MCR03 hydraulic motors for equipment replacement, maintenance, repair and rebuild projects.

Complete motors are available for customers who need to replace an existing hydraulic motor rather than rebuild individual internal components. Depending on the application, the correct motor configuration may vary by displacement, shaft, mounting arrangement, brake configuration and other options.

Rexroth MCR3 MCR03 Hydraulic Motor

The MCR3 MCR03 series is commonly used in mobile and construction equipment where high torque and compact hydraulic drive solutions are required. We supply aftermarket replacement motors for applications using Rexroth MCR3 / MCR03 configurations.

Because MCR3 and MCR03 motors are available in different configurations, the complete model code or reference number is important when selecting a replacement motor. A motor that looks similar externally may have different displacement, shaft, mounting or braking specifications.

MCR3 MCR03 Hydraulic Motor for Caterpillar Applications

MCR3 MCR03 hydraulic motors are also found in Caterpillar equipment and replacement applications. Caterpillar parts information identifies MCR3 radial piston motor applications on equipment including models such as the 216B, 226B, 232B and 242B, as well as other skid steer and multi-terrain loader models.

For some Caterpillar applications, the motor may be identified by a Caterpillar part number rather than the original Rexroth model code. For example, Caterpillar 370-6073 is commonly associated in the replacement market with the Rexroth MCR3A400A45Z32B2M1L12F1P0SO522E motor and Rexroth reference R921811109.

When ordering a replacement motor for Caterpillar equipment, we recommend checking the machine model, existing motor nameplate and Caterpillar part number together before confirming the order.

Common MCR3 MCR03 Models and Reference Numbers

The following are examples of MCR3 MCR03 motor configurations and reference numbers that are commonly found in the replacement market. They are provided as reference only, as the final motor configuration should always be confirmed against the original motor.

Complete MCR3 MCR03 Hydraulic Motor for Replacement

A complete MCR3 MCR03 hydraulic motor can be used when the existing motor requires full replacement because of internal wear, mechanical damage or other service conditions. This can be a practical solution for equipment repair and maintenance projects where rebuilding the original motor is not the preferred option.

SEIMT supplies aftermarket complete motors for replacement and rebuild projects. The motor can be supplied according to the required configuration, with the exact specification confirmed from the original motor information before shipment.

Typical Replacement Applications

• Caterpillar and other construction equipment
• Hydraulic travel and drive systems
• Mobile machinery requiring low-speed high-torque hydraulic motors
• Hydraulic motor replacement and maintenance projects
• Equipment repair and hydraulic system rebuild projects

How to Identify the Correct MCR3 MCR03 Hydraulic Motor

The MCR3 MCR03 series includes many configurations, so identifying the correct complete motor by appearance alone is not recommended. Before ordering, please provide as much of the following information as possible:

• Motor nameplate or identification plate
• Complete Rexroth MCR3 / MCR03 model code
• Rexroth reference or part number
• Caterpillar machine model and part number, if applicable
• Clear photos of the motor, shaft and mounting interface

For applications such as Caterpillar 216B, 226B and other equipment using MCR3 motors, providing the machine model together with the motor nameplate or part number helps us check the correct replacement configuration more accurately.

Need MCR3 MCR03 Spare Parts or Seal Kits?

Not every hydraulic motor requires complete replacement. For customers who prefer to repair or rebuild the existing motor, we also supply MCR3 / MCR03 spare parts including major internal replacement components.

For sealing maintenance or repair, see our MCR3 / MCR03 seal kit for replacement sealing components.
