Reman/Exchange Parts

Your business depends on the equipment you own and the quality of repair parts you use. Over the life of your equipment, you periodically replace parts to support your overall investment and keep your equipment running strong. Cat® Reman parts give you another way to access genuine Cat parts quality, offering same-as-new performance at fraction-of-new costs.
Remanufacturing is the process of returning an end-of-life, broken or blemished product to “same-as-new” condition in a manufacturing environment.

Good for Customers
Cat Remanufactured Parts and Components provide same-as-new performance and reliability at a fraction of the cost of new parts-while reducing the negative impact on the environment. The results are maximum productivity and lower costs.

Good for Business
The remanufacturing program is based on an exchange system whereby you return a used component (core) in return for our remanufactured products. Reman options are one more way we support your equipment and help you lower owning and operating costs.

Good for the Environment
Because we are in the business of returning end-of-life components to same-as-new condition, we reduce waste and minimize the need for raw material to produce new parts. Through remanufacturing, we make one of the greatest contributions to sustainable development—keeping nonrenewable resources in circulation for multiple lifetimes.
Massy Cat’s Re-manufactured Cat components offer attractive benefits.

  • Up to 60% cost saving over new
  • Same as-new warranty
  • Environmentally friendly – fewer parts are thrown away, reducing landfill pollution. And what was once viewed as waste is now being reused
    Components can be upgraded to utilize the latest technology advances

Ground Engaging

Selecting the right Ground Engaging Tool (GET) is critical to achieving the maximum return on your machine investment. GET protects the expensive parts of your blades, buckets and ripper shanks, resulting in longer life and reducing maintenance costs. GET also plays a big part in determining how well your machine performs in a specific application.

At Massy Cat, we offer many GET options, because every machine and application has its own special needs. Massy Cat’s GET specialists are well trained and experienced in matching the right tools to the application.


Cat Advansys is built for machine productivity, balancing tip wear material and penetration requirements. Integrated hammerless retention ensures you are back to work in minutes without a separate retainer.

Wider top surface reduces drag on the tip and adapter side as the tip moves through the material. Reduced side drag results in less force required to move the hex bucket through the material.

Adapter design directs material flow over adapter strap, which can extend adapter service life and bucket lifecycle.

Hammerless system. A 3/4 inch retainer lock requires no special tools for installation and removal.

Available for 950 through 994 Wheel Loaders and 311 through 390 Hydraulic Excavators.


The hydraulic system of a machine plays a key role in its level of productivity. The condition of your machine hydraulics is directly related to the amount of work done and the costs associated. No matter how well built or managed a machine is, its hydraulic system will eventually need servicing. The decisions you make about the maintenance and servicing of these systems directly affects your bottom line.

At Massy Cat, we understand the importance of operating and maintaining a clean and efficient hydraulic system. We are committed to providing you with the best possible option to ensure that your equipment’s hydraulic system is operating at maximum efficiency. Our workshop is fully equipped to help you get the most out of your hydraulic systems for the lowest possible cost.

Massy Cat combination of repair options, service expertise and the support of the Cat® parts system will get you back to work fast.

Cylinder & Rods

Most new and Cat Reman cylinder rods are induction-hardened and inertia-welded. The resulting superior strength and dent resistance deliver longer component life and reduced risk of system contamination.

Cat cylinders feature an innovative sealing system that absorbs pressure spikes, withstands side loading, and guards against contaminant entry better than competitive designs.
