Without specific product documentation from Caterpillar, it's difficult to determine the exact displacement value precisely. However, for hydraulic piston pumps used in wheel loaders of this class, the displacement is an important parameter that affects the pump's ability to supply hydraulic fluid to power various functions such as bucket lifting, arm articulation, and steering. The displacement could typically range from several tens to a few hundred cubic centimeters per revolution (cm³/rev). A higher displacement value generally means the pump can move more fluid per revolution, enabling faster and more powerful operation of the loader's hydraulic actuators.
Operating Pressure
These pumps are designed to withstand high pressures to meet the demanding requirements of wheel loader operations. The maximum operating pressure is a critical specification. In the case of pumps for Caterpillar 980G and 980H wheel loaders, the maximum operating pressure could be in the range of 200 bar (20 MPa) to 400 bar (40 MPa). This high pressure is necessary to drive the large hydraulic cylinders and motors that perform the heavy lifting and moving tasks of the loader. The actual maximum operating pressure for the 1053635/105-3635 pump would need to be confirmed from Caterpillar's official specifications.
