Identify the signs, don’t wait for failure!
21 October, 2021
For optimal hydraulic system operation, the performance and durability of your pumps and motors is critical. Waiting for a breakdown can result in unplanned downtime and additional costs.
WHY ARE CAT® MOTORS AND PUMPS THE BEST CHOICE?
Genuine Cat pumps and motors offer high standards of quality and reliability. They are designed by Caterpillar to deliver optimum performance for Cat machines. Cat engines and pumps are made of very high quality materials to help provide strength, power, productivity and reliability. Make sure to keep an eye out for warning signs and repair indicators. The table below highlights some of the key repair indicators and possible causes. Keep an eye out for them or talk to your Cat dealer about the right service options. They ensure that customers always have the right parts and service solutions, customized for their equipment and operation. With their expertise in Cat components and their applications, your dealer can guide you in fine-tuning and optimizing your hydraulic pump and engine control settings. Their diagnostic services can identify problems and provide solutions. Many Cat dealers use specialized equipment, such as a test bench, to test and adjust pumps and motors, helping them to be more needed in their repair and replacement recommendations. This can reduce rework and keep your service and repair bills to a minimum. That is Aftermarket Smarts.
