Don’t forget about the impressive Remanufacturing options the Altorfer  Cat Parts & Service Department offers. Remanufacturing is the process of returning a product at the end of its life to same as “new” condition in a manufacturing environment. It operates as a one-for-one exchange, where end-of-life products are returned for a remanufactured product — reducing waste and minimizing the need for raw materials to produce a brand new item. Cat Reman offers you a sustainable business model and high-quality, lower cost product support option.

Cat Remanufacturing offers:

  • Off-the-shelf availability
  • Same as new warranty and quality
  • Fraction of new price
  • Lower owning and operating costs
  • Worldwide availability
