Name: Rexroth A10VG Hydraulic Pump Service Manual
Author: Rexroth

Within the hour you could have an A10VG clamped on the bench with its boost pump cover off, and this Rexroth A10VG service manual PDF is the 54-page factory repair manual (OEM ID 647255EN-DE) for that hydraulic pump. Sectional views open the book and trace the pressure cut-off, control unit, rotary group and positioning piston, so you know what sits behind each fastener before you touch it. The procedures that follow cover sealing the drive shaft, boost pump and valves, pulling the rotary group, fitting the Turcon-Glyd-ring and servicing the HW, DA, HD and EP control units. A good share of the back of the book goes to adjustment: mechanical and hydraulic zero position, high pressure valves and pressure cut-off. Set boost pressure to 18 bar nominal, with a 40 bar peak, and tighten the pole tube to 19 Nm. It's just you, a bare housing and nobody to ring. Bookmarked, text-searchable and bought once, it stays yours for as long as this pump runs.
