    The pillar of the USCO product range, repair parts represent the kingpin around which the Modenese company has grown and developed since its creation and in the course of the 90’s. The product range has continuously been developed over time, not only by  building up the distribution network, but also through acquisitions aimed at the manufacture of more delicate products. In parallel, USCOhas considerably bolstered the Engineering and R&D Departments from a qualitative and a quantitative point of view developing  strong design expertise.  Another important aspect that makes the ITR repair parts stand out lies in the numerous quality controls carried out at its production plants, at its suppliers, and when the products come into the USCO warehouses. These controls guarantee that the high level of quality is maintained for all the macro areas in which the repair parts department is divided, that is to say, engine, hydraulic, transmission and frame parts being the pulsating heart of an earth moving machine must be kept under tight and constant control. USCO can today boast to be a company offering one of the most complete product ranges in the world, permanently available on stock. USCO, through ITR Meccanica, has an annual production capacity of 60.000 pumps with more than 400 different types for Caterpillar and Komatsu machines.All the items in the ITR spare parts range can be ordered online via the dedicated e-commerce section.
