LEARN ABOUT THE CAT DIFFERENCE
We offer repair options for a wide range of specific needs and budgets. Choose anything from reseals to full rebuilds, replacements with Cat® Reman or new components, and you’ll get the most up-to-date engineering improvements to maximize machine productivity and component life.
Engine Parts
Engine parts must endure incredible stresses and extreme temperatures - so Caterpillar continually improves its design and manufacturing processes to ensure Cat engine components work hard as a complete system and can be remanufactured for a second life.
Pumps and Motors
For real benefits, choose Cat® pumps and motors. Don’t wait for failure – this can lead to unplanned downtime and additional costs. Look out for the warning signs that include excessive noise or vibration.
Hydraulic Hoses and Couplings
Cat® is the only major OEM to build its own hose products, and continue to invest in improving engineering, reliability and value to make sure you get the safest, most dependable hose possible.
Cat® Remanufactured Parts
Remanufacturing is the process of returning an end-of-life, broken or blemished product to "same-as-new" condition in a manufacturing environment.
Batteries
Cat® Batteries stand up to intense vibration and deliver dependable starting power in any condition or application. They can be used across all construction and power generation brands.
Filters and Fluids
Cat® filters and fluids provide the superior quality and protection you need to maximise your engine and other component system’s life.
Cylinders and Rods
Hydraulic cylinders and rods provide the muscle for your machines. And just like your own muscles, they need proper care.
Ground Engaging Tools
Protect expensive machine components. Reduce your operating costs. And get the most out of your machine's performance.
Undercarriage
Your undercarriage accounts for up to 50% of your machine’s owning and operating costs, so it makes sense to invest in a system that will deliver the most value. We have the expertise and options to suit any application.
Drivetrain
Final drive and transmission parts work together to transmit power to the ground and propel Cat® earthmoving equipment through a variety of applications all over the world. Genuine Cat drive train parts, along with excellent maintenance and repair options.

What Good Maintenance Looks Like
It’s no secret that regular maintenance protects both your machines and your business. But what does good maintenance look like?
Protecting Against Hydraulic Contamination
Hydraulic contamination can have a dramatic effect on your machine - increasing wear, reducing efficiency and costing you money.
The Inside Story on Cat Filters
Contamination, even by particles too small to see, costs money. Whether that cost comes from low productivity, increased maintenance work or component failures, contaminants can cause serious damage to machinery.
Undercarriage Through The Years
The undercarriage is – quite literally – the component that keeps machines driving along. Not only that, it is also responsible for about half a machine’s owning and operating costs.
The Story of Hydraulic Contamination
Modern hydraulic systems produce more power and have finer control than those of the past due to precision engineering and closer fitting parts. The downside is the increased danger of foreign contaminants damaging machines.
