Our used CATERPILLAR hydraulic parts come with a 12-month warranty after refurbishment in our specialized workshops. Each hydraulic component undergoes rigorous bench testing simulating real usage conditions, validating performance under pressures up to 400 bars to ensure your peace of mind.

Verification begins with precise identification of your excavator's model and its machine serial number. Check the data plate to gather these essential details, then verify the references of existing hydraulic components. Our specialists analyze this information to confirm the perfect fit for your Caterpillar machine from series 312 to 349.

Reconditioned hydraulic pumps have technical characteristics that vary depending on the Caterpillar machine model concerned. Selection mainly depends on the type of pump (main, secondary, swivel), displacement, and complexity of your earthmoving machine's hydraulic system. Our specialists assist you in choosing the component best suited to your specific needs.

Maintenance of CATERPILLAR swivel hydraulic motors requires hydraulic oil changes every 2000 operating hours along with replacement of high-pressure filters. Regularly check the sealing of O-rings and watch for leaks around fittings. Clean the hydraulic cooler to maintain optimal temperature and bleed the circuit to remove air.

Mixing new and used components is technically possible on a Caterpillar hydraulic circuit provided that pressure specifications and manufacturer references are respected. Verify the compatibility of operating pressures among all elements and ensure that seals and fittings withstand the same stresses to avoid premature failures.

Replace hydraulic distributors when movements become jerky, slow, or imprecise despite correct circuit pressure. Visible external leaks, unusual noises during operations, and loss of cylinder power are also warning signs requiring immediate replacement to avoid damage to other hydraulic components.
