Part of the Doosan Repair Manuals.
This is the factory shop manual for the Doosan DX140LC-5 crawler excavator, publication 950106-01141E, 1st Edition February 2015. It covers the whole machine: the Perkins 1204F Tier 4 Final engine rated 81.6 kW at 2,000 rpm (page 167), the main pump and control valve with real test specs, swing device, joysticks, cab and ROPS, swing bearing, boom and arm in both one piece and two piece versions, plus full hydraulic and electrical system chapters. The back of the book carries the oversize foldout hydraulic schematic (page 1503) and electrical schematic (page 1504). Fault code tables are printed too, engine ECU codes on page 1328 and panel communication codes on page 1367. This is the book the dealer techs work from.
