That chapter list is the skeleton of a full machine teardown. Each SP-numbered section is a standalone service document – SP002261 covers the engine in full, SP002169 covers the K3V280DTH main pump, SP002171 covers the main control valve, SP002181 covers the pump regulator, and SP002140 covers the electrical system. The result is a shop manual that can be used section by section, so a technician working on the hydraulic system does not have to wade through engine overhaul data.

What This Manual Enables

Because the Doosan DX700LC is a large crawler excavator, the range of jobs this manual supports is broad. Engine mechanical work is covered in full: cylinder head removal and disassembly, rocker arm inspection and reassembly, camshaft disassembly and end-play measurement, timing gear and idle gear backlash, flywheel and flywheel housing, piston and connecting rod inspection, crankshaft runout, cylinder block and liner measurement. Cooling system, fuel system, lubrication system and turbocharger each get their own chapter with removal, inspection, reassembly and torque specifications.

The hydraulic section is where a lot of DX700LC work will concentrate. The main pump chapter covers the K3V280DTH twin-pump assembly – disassembly, inspection, reassembly, and the pump main body maintenance standard with wear limits for the piston, shoe thickness, cylinder spring free height and set plate clearance. The regulator chapter explains the KR3D-ZP53-V and KR3D-ZP54-V regulator operation – horsepower control, power shift control, flow control – and provides the adjustment table for maximum flow, minimum flow, input horsepower and flow control attributes.

Control valve work is documented at spool level. The main control valve chapter walks through neutral passages, single operation, combined operation, anti-drift valve operation, main relief valve and overload relief valve function, then covers disassembly and reassembly of the main spools, sub-spools, swing load check, load checks and relief valves, with torque values for every plug and flange. The remote control valve (joystick) and travel control valve (with damper) each have their own procedures.

Cylinder repair is covered in a dedicated chapter – piston and cylinder head assembly, seal ring, buffer ring, U-ring, wiper ring, bushing replacement, torque for piston nut and cylinder head bolts, and the wear limits for piston rod outside diameter, rod bushing inside diameter and piston slide ring thickness.

The swing and travel functions have full motor and reduction gear coverage. The M2X210 swing motor chapter includes the theory of operation, time delay valve, brake section, service limits for piston diameter, cylinder bore, shoe flange thickness and brake friction plate. The travel motor chapter covers the MSF-340VP series with counter balance valve, two-speed change mechanism, parking brake and relief valve operation. The travel reduction gear chapter covers the planetary unit with disassembly, reassembly and final test procedures.

Electrical coverage is extensive. The electrical system chapter documents the 24V supply, engine starting circuit, preheating, charging, monitoring system, the e-EPOS electronic hydraulic control system with power mode and economy mode control, engine control dial, automatic deceleration, engine overheat protection, power boost, automatic travel speed control, and the self-diagnostic function with failure codes. The air conditioner, wiper, lighting, overload warning and audio systems have their own procedures.

Specifications and Service Data

Throughout the Doosan DX700LC Shop Manual, every procedure is backed by the numbers needed to complete it correctly. Torque values for standard metric and U.S. fasteners, Type 8 phosphate coated hardware, hose clamps and split flanges. Maintenance standards for the engine – valve clearance, compression pressure, cylinder liner bore, crankshaft runout, camshaft runout, piston ring end gap and connecting rod bearing clearance. Hydraulic pressures – main relief at 320 kg/cm2 normal and 350 kg/cm2 pressure up, pilot pressure 40 +/- 5 bar, swing relief 300 kg/cm2, and the pressure settings used across the various control valves. Actuator speeds for boom, arm, bucket, swing and travel, plus the natural drop test limits.

Machine specifications are also included – shipping weight, operating weight, major component weights, digging forces, fuel tank capacity 900 liters, hydraulic system capacity 790 liters, hydraulic reservoir capacity 350 liters, and the working range dimensions for the standard boom and arm combinations.

Who This Manual Is For

This Doosan DX700LC Shop Manual is written for the technician who is going to actually take the machine apart. The procedures assume the reader has a workshop, lifting equipment, hand tools and the special tools called out where required. It is not a simplified owner’s guide – it is the full service documentation set, with disassembly and reassembly sequences, inspection criteria, wear limits, torque values and test procedures for each system.

Independent repair shops, fleet maintenance departments, and owner-operators who do their own servicing will all find the section-level structure useful. Because each SP-numbered document is a complete service guide for its component, the Doosan DX700LC Shop Manual works both as a full reference and as a quick lookup when only one system needs attention.

Instant PDF Delivery

The Doosan DX700LC Shop Manual is delivered as an instant PDF download – no shipping, no waiting for a physical book. Once payment is complete the file is available for download and can be viewed on a laptop, tablet or phone in the workshop, or printed for the pages you need at the machine. Having the full Doosan DX700LC Shop Manual on hand means the correct specification and procedure are always within reach, and the job gets done to the standard the machine was built for.
