UNIQUELY DESIGNED FOR CAT MACHINES

Precisely matched to your machine specs, Cat pumps and motors protect your productivity and profits. Only genuine Cat parts can ensure optimized machine performance, long component life and the option to rebuild if you wear them out.

100% TESTED TO PERFORM

Get back to work fast with pumps and motors ready to run right out of the box. Only genuine Cat parts can ensure that you get same-as or better-than-new performance, validated for durability through on-machine testing, and rigorously tested and inspected when the pump or motor is made. If you purchase a pump from a competitor, there may be additional labor to adjust the pump to meet the hydraulic system specifications.

12-MONTH CAT PARTS WARRANTY

Work worry-free knowing that Cat covers the parts and even more when installed by Yancey. Did you know that no competitor covers resultant damage when a part fails? When Yancey installs the parts, both repair labor and resultant damage are covered. That is part of the genuine Cat parts warranty advantage. For peace of mind you can trust, choose genuine Cat parts. A pump or motor failure repair can cost over $100,000 USD if other parts are damaged and a hydraulic system clean-out is needed. Contact us for full warranty details.
