The factory workshop manual for seven Liebherr excavators of one family - wheeled A 308, A 310B, A 312 and A 316, plus crawler R 308, R 310B and R 312.
Nineteen repair groups bound from three volumes cover the engine (BF 4 M 1011 F / BF 4 M 2011), splitterbox, hydraulic pumps and components, swing gear and swing ring, two speed travel gearbox, axles, steering, oscillating axle stabilizer, brakes, cab and heater.
You get electrical circuit diagrams, the full hydraulic circuit diagram, and the pressure values that actually matter on these machines: 320-10 bar operating, 32+/-1 bar servo on the R 312. Text runs trilingual German/English/French. It is a scan with no text layer, but real PDF bookmarks jump you straight to each group.
