This is the factory Caterpillar repair set for the 226B3 skid steer loader with the Cat C2.2 diesel, 2008-2014 machines, bundled as 15 section PDFs totaling 2440 pages. You get all three layers Cat dealers work from: Systems Operation to understand how a circuit is supposed to behave, Testing and Adjusting with real numbers (main relief 23000 kPa / 3336 psi, charge pressure 3100 kPa at low idle, high idle 3195 rpm), and Disassembly and Assembly for the actual wrench work. The test procedures are Cat's family-wide B3 series content, so they apply to your 226B3 exactly as the dealer would run them. Coverage runs from the hydraulic system and power train through the fuel, cooling, electrical and operator station.
