MCR5 MCR05 Hydraulic Motor | Rexroth & Caterpillar

Moteur hydraulique MCR5 / MCR05

The MCR5 MCR05 hydraulic motor is a radial piston hydraulic motor designed for high-torque, low-speed drive applications. SEIMT supplies complete aftermarket MCR5 / MCR05 hydraulic motors for equipment replacement, maintenance, repair and rebuild projects.

A complete replacement motor can be a practical solution when the existing hydraulic motor has extensive wear or damage, or when replacing the complete unit is more suitable than rebuilding individual components.

Rexroth MCR5 / MCR05 Hydraulic Motor

The Rexroth MCR5 / MCR05 series is used in mobile and construction equipment where compact hydraulic drive systems require high torque at relatively low operating speed. Different motor configurations may use different shaft, mounting, displacement, braking or control arrangements.

For this reason, the MCR5 or MCR05 designation alone may not be sufficient to identify the correct replacement motor. The original motor model, nameplate and configuration should be checked before an order is confirmed.

MCR5 / MCR05 Hydraulic Motor for Caterpillar Applications

MCR5 / MCR05 radial piston motors are also found in Caterpillar mobile and construction equipment applications. Replacement motors may be required when an MCR5 motor used on Caterpillar equipment needs to be replaced during machine repair or maintenance.

For Caterpillar applications, the machine model and Caterpillar part number can help identify the correct hydraulic motor configuration. We recommend providing these details together with the motor nameplate whenever available.

Complete MCR5 / MCR05 Hydraulic Motor for Replacement

A complete MCR5 / MCR05 replacement motor can be supplied for customers who need to replace an existing motor without rebuilding every internal component. This option may be suitable for equipment repair projects where minimizing downtime and simplifying the replacement process are important.

Typical Applications

• Construction and mobile equipment
• Hydraulic travel and drive systems
• Caterpillar equipment using MCR5 / MCR05 motor configurations
• Hydraulic motor replacement and maintenance projects
• Equipment repair and hydraulic motor rebuild projects

MCR5 / MCR05 Motor Replacement or Rebuild?

Replacing the complete motor is not always necessary. If the housing and major internal components remain suitable for reuse, individual components can be replaced during a hydraulic motor repair or rebuild.

For customers repairing an existing motor, we also supply MCR5 / MCR05 Spare Parts for selected internal and replacement components.

When the main issue is external oil leakage or worn sealing components, a MCR5 / MCR05 Seal Kit may be a more suitable repair option.

How to Identify the Correct MCR5 / MCR05 Hydraulic Motor

MCR5 / MCR05 motors are available in different configurations, so the complete model identification is important when selecting a replacement. Please provide as much of the following information as possible:

• Plaque signalétique ou plaque d'identification complète du moteur
• Full MCR5 / MCR05 model code
• Référence ou numéro de pièce Rexroth
• Caterpillar machine model or part number, when applicable
• Clear photos of the motor, shaft and mounting interface

Providing the original motor information helps us confirm the required displacement, shaft and mounting configuration before supplying a complete replacement motor.

MCR5 / MCR05 Hydraulic Motor Troubleshooting & Repair

If the motor is not rotating, running slowly, overheating, making abnormal noise or leaking oil, the complete hydraulic system should be checked before deciding whether the motor needs replacement.
