Doosan DX340LC-5 DX350LC-5 Excavator Shop Manual 950106-01001E – April 2014

This Doosan DX340LC-5 DX350LC-5 Excavator Shop Manual 950106-01001E – April 2014 provides detailed service and repair information for DX340LC-5 and DX350LC-5 excavators with Serial Number 10001 and Up. Across 1,631 pages, it brings together machine specifications, performance standards, component service procedures, hydraulic and electrical information, engine repair data, adjustment procedures, troubleshooting, torque specifications, attachment systems, and schematics.

The manual is organized around the excavator’s major assemblies, allowing a technician to move from machine-level specifications and testing into individual components such as the main pump, control valve, swing device, travel device, front attachment, cylinders, and electrical and hydraulic circuits. Removal, installation, disassembly, reassembly, inspection, testing, and troubleshooting information is included throughout the relevant sections.

Machine Specifications and Performance Information

The specifications section of the Doosan DX340LC-5 DX350LC-5 shop manual identifies component locations and provides general dimensions for both one-piece and two-piece boom configurations. Working-range information covers different arm and bucket combinations, while general specifications include machine weights, digging forces, tank and hydraulic capacities, bucket capacity ranges, shoe choices, and ground-pressure data.

Performance testing receives its own detailed coverage. The manual explains test preparation, test-area requirements, measurement practices, and performance standards before moving into procedures for hydraulic cylinder cycle times, travel speed, track revolution speed, mistrack, swing speed, and swing drift. This gives technicians defined methods for comparing actual machine operation with the standards printed in the manual instead of relying only on subjective symptoms.

Examples of machine data included in the manual include a shipping weight of 34.9 tons (76,941 lb), a 600 liter (158.5 U.S. gal) fuel tank, 450 liter (118.8 U.S. gal) hydraulic system capacity, and 240 liter (63.4 U.S. gal) hydraulic reservoir capacity. The bucket heaped capacity range is listed as 1.25 – 2.01 m3 (1.63 – 2.63 yd3), with additional dimensional and working-range data provided for the available front configurations.

DC 9 Engine Service and Repair Coverage

A substantial engine section covers the DC 9 engine fitted to the machines in this manual. Engine specification data identifies a 5-cylinder, straight, 4-cycle water-cooled engine with air-to-air intercooling and direct injection. Rated net power is listed as 237 kW (318 HP) at 1,800 rpm, displacement as 9,300 cc, bore as 130 mm, stroke as 140 mm, and compression ratio as 17:1. The engine section also contains identification information, performance curves, special tools, tightening torques, inspection procedures, and extensive component-level repair instructions.

Coverage extends through the cylinder head, valve mechanism, cylinder block and liner, camshaft, connecting rod, crankshaft, flywheel, piston, roller tappet, timing gear, lubrication system, exhaust and aftertreatment components, cooling system, fuel system, and engine electrical controls. Fuel-system subjects include the accumulator, fuel manifold, overflow valve, feed pump, injectors, filter and heater, together with troubleshooting. Exhaust-system coverage includes the variable geometry turbocharger, oxidation catalytic converter, EGR system, reductant components and related sensors. The manual also provides numerous component-specific tightening procedures and torque values for engine assembly work.

Hydraulic Service, Testing and Troubleshooting

Hydraulic information is spread through both component chapters and dedicated hydraulic-system sections. The manual covers the main pump, main control valve, swing device, fan pump and fan motor, joystick and travel control valves, solenoid valve, accumulator, center joint, travel device, cylinders, hydraulic tank and related circuitry. General hydraulic maintenance guidance emphasizes system cleanliness, contamination prevention, oil-leak inspection, correct assembly practices and pressure-release precautions.

The dedicated hydraulic chapters explain system operation and include testing, adjustment and troubleshooting information. The hydraulic system identifies major components such as the two main pumps, control valve, swing and travel devices, boom, arm and bucket cylinders, pilot components, valves, filters, oil cooler, hydraulic tank, attachment-control valves and associated circuits. This makes the manual useful both when tracing a hydraulic function and when servicing the individual hardware responsible for that function.

Component Removal, Overhaul and Installation

The Doosan DX340LC-5 DX350LC-5 Excavator Shop Manual contains component-focused sections for the upper structure, undercarriage and front attachment. Depending on the assembly, these sections include specifications, parts identification, theory of operation, inspection, removal, installation, disassembly, reassembly, maintenance standards and troubleshooting. The swing device section, for example, covers the swing motor, reduction gear, parking brake, hydraulic circuit, removal and installation, complete disassembly and reassembly, troubleshooting and worn-part standards.

The lower structure covers the swing bearing, center joint, travel device and track assembly. Front equipment coverage includes the boom and arm, bucket and hydraulic cylinders. Procedures are supported by component illustrations, connection information, tightening values and service precautions where applicable.

Torque and Assembly Reference

General maintenance material includes welding precautions, hydraulic-system precautions, cleaning and inspection methods, bearing inspection and repair practices. A dedicated standard-torque section contains metric and U.S. fastener torque charts, Type 8 phosphate-coated hardware values, hose-clamp values, ORFS swivel nut recommendations, split-flange torque values and information on torque-wrench extension tools. Separate engine pages provide normal and special tightening torques as well as component-specific sequences for assemblies such as the cylinder head, connecting rods, flywheel, fuel system and other engine parts.
