Factory Caterpillar SIS repair manual bundle for the 236, 246, 252 and 262 skid steer loaders, serial prefixes 4YZ, 5SZ, FDG and CED (roughly 2004-2011 hydrostatic machines with the CAT/Mitsubishi diesel). This is the real dealer service literature, split into section PDFs: engine, hydrostatic power train, hydraulic testing and adjusting, electrical and starting system, operator station, implements and work tool coupler, plus full electrical and hydraulic schematic libraries and standard fastener torque charts. The hydraulic section has the numbers you actually need at the gauge - charge pressure 3300 kPa (480 psi) at high idle, pilot pressure 2500 kPa (365 psi), accumulator charge 900 kPa (130 psi). Searchable PDFs, instant download, print what you need.
