All 41 pages of this Linde HPV repair manual cover the complete axial piston pump family: HPV 55 ... 135-02, and the HPV...-02R variant. Inside, you get hydraulic schematics with full port identification (high-pressure, boost pump suction, control pressure supply, and drain), plus a full set of exploded views walking you through every sub-assembly from the rotating unit and valve plate housing down to the boost pump and servo control. Step-by-step procedures take you through complete disassembly, bearing adjustment, swash plate assembly, and M1, H1, and E1 control device mounting, with a dedicated tightening torques table covering standard and fine-pitch threads across property classes. Set cylinder barrel lift-off clearance to 0.1-0.3 mm; keep your mechanical zero position within 0.06 mm side-to-side or the pump will never track straight. Your machine is down. Get the numbers right the first time. Bookmarked by section so you can jump straight to bearing preload, shaft seal specs, or torque values without scrolling.
