MCR3 MCR03 Seal Kit | Rexroth & Caterpillar

Rexroth MCR3 / MCR03 Seal Kit

The MCR3 MCR03 seal kit is an aftermarket replacement sealing solution for Rexroth MCR3 / MCR03 radial piston hydraulic motors. It is suitable for hydraulic motor repair, maintenance, overhaul and rebuild applications.

Worn or damaged seals can cause hydraulic fluid leakage and affect the sealing performance of the motor. Replacing the seals during routine maintenance or motor overhaul can help restore proper sealing and reduce the risk of contamination and premature component wear.

MCR3 / MCR03 Seal Kits for Caterpillar Applications

MCR3 / MCR03 radial piston motors are also found in Caterpillar construction and mobile equipment. For customers repairing Caterpillar equipment equipped with MCR3 motors, a replacement Caterpillar MCR3 / MCR03 seal kit may be required when the original motor is being serviced or rebuilt.

The correct seal kit depends on the motor configuration, so the Caterpillar machine model, motor identification and original part information should be checked before ordering.

Seal Replacement for Repair & Rebuild

The MCR3 / MCR03 seal kit can be used when the existing hydraulic motor is being repaired instead of replaced as a complete unit. It is suitable for maintenance work, hydraulic motor overhaul and rebuild projects where sealing components need to be renewed.

If the motor requires replacement of major internal components, see our Pièces de rechange MCR3 / MCR03 page for additional replacement components.

How to Identify the Correct MCR3 / MCR03 Seal Kit

MCR3 / MCR03 motors are available in different configurations, so the correct seal kit should be confirmed from the original motor information whenever possible. Please provide the motor nameplate, complete model code, original seal kit reference, part number or clear photos of the motor.

For Caterpillar applications, please also provide the machine model and Caterpillar part number when available. This information helps us check the correct replacement seal kit for your application.
