The factory service manual Liebherr issued for the A 900, A 902, A 912, A 922 and A 932 Litronic wheeled excavators, split into nineteen bookmarked repair groups running from safety and service fluids through diesel engines, hydraulics, electrics, swing gear, axles, steering, brakes and the hydraulic tank.
Engine data covers the Deutz BF 4 L 913, the Deutz BF 4 M 1013 E and Liebherr's own diesels. The hydraulic groups walk through operating pressures, pressure checks and relief valve adjustment on the variable displacement double pumps, and the electrical group carries the basic machine schematic plus circuit board and slip ring coverage.
It is a scan of the paper book - no text search, but real PDF bookmarks jump you straight to each group.
