Part of the New Holland Repair Manuals.
The New Holland E80BMSR workshop manual, print number 84365680B, edition 09/2010, 948 pages on the E80BMSR midi excavator. The Outline and Specifications section carries the numbers a buyer checks first: the Isuzu AU-4LE2X water-cooled 4-cycle direct injection diesel with intercooler turbocharger, rated output net 41 kW / 2,200 min-1 to ISO 9249 and net 42 kW / 2,200 min-1 to ISO 14396, fully equipped weight 8,730 kg (19,250 lbs), and an 8-spool control valve fed by a variable displacement axial piston plus gear pump.
Two drawings from the book are rendered on this page. The electric circuit diagram runs as sheets 1 to 8 starting at page 185, drawn around the Mechatro controller TCO-60-2 with every pressure sensor named at its pins, the key switch terminal table, the relays and solenoids, and every wire carrying its code, gauge and colour. The hydraulic circuit drawing on page 158 shows the main pump, hydraulic tank and main control valve with its 32.3 MPa settings, plus a parts table naming the control valve, boom, swing and dozer cylinders and pilot valve with their part numbers.
Pages 721 to 948 are a complete Isuzu 4LE2 engine manual bound in behind the machine book, with its own section numbering, from cylinder head to preheating circuit.
