Daewoo Solar 130LC-V, Solar 170LC-V, Solar 220LC-V, Solar 250LC-V, Solar 220N-V 2001 Service Manual

You’ve got a Daewoo Solar excavator in the shop with a hydraulic leak, a dead swing motor, or a track that won’t tension. The aftermarket PDF you obtained from some forum says the pilot pressure should be “around 400 psi” – but that guess cost you two hours and a blown seal. The Daewoo Solar 130LC-V, Solar 170LC-V, Solar 220LC-V, Solar 250LC-V, Solar 220N-V 2001 Service Manual is 582 pages of factory-correct data. No third-party rewrites, no missing pages. This is what Daewoo engineers wrote for their own dealers.

Every model listed on the first page – Solar 130LC-V (serial 0001 and up), 170LC-V (1001+), 220LC-V (0001+), 220N-V (1001+), and 250LC-V (1001+) – gets its own specifications and procedures. The manual covers the whole machine: engine, hydraulics, upper structure, lower structure, and drive train. You want the charge pressure for the travel motor? It’s in the hydraulic section. Need the removal sequence for the swing reduction gear? That’s chapter 4. I’ve used factory manuals for twenty-eight years, and this one doesn’t hide the numbers.

Safety Section: Not a Suggestion

The first 21 pages are dedicated to track excavator safety. The manual opens with a direct warning: “Unsafe use of the excavator could lead to serious injury or death.” It walks through general safety essentials, location of safety labels, and a summary of precautions for lifting in digging mode. Page 1 lists every Solar model covered – including the 220N-V and 250LC-V – with their serial number ranges. You get sections on work-site precautions, operation, equipment, maintenance, and shipping. The lifting-with-sling procedure alone saves you from guessing the center of gravity. If you’ve ever seen a counterweight drop because someone used a too-short chain, you’ll appreciate the diagrams.

Torque Specs and Standard Fasteners

The “Standard Torques” subsection under General Maintenance gives you torque values for metric fasteners, U.S. fasteners, Type 8 phosphate coated hardware, hose clamps, split flanges, and torque wrench extension tools. No more pulling an internet chart that may or may not match your excavator’s bolts. The table lists torque in N·m and foot-pounds – the manual was published for a global market, but the U.S. fasteners section is what you need for older SAE hardware. I’ve had guys strip a boom cylinder bolt because they used a generic automotive spec. This manual stops that.

Hydraulic System Troubleshooting: Where the Time Goes

The hydraulics chapter fills over 100 pages. It starts with general notes, a full hydraulic schematic, and operation of working components. Then it moves into procedural troubleshooting baseline recommendations. You get dedicated sections for pilot pressure, power mode valve, boom/front priority valve, pressure up valve, and pump input power control. The flow meter and flow meter kit installation procedure tells you exactly how to tap into the system without damaging the pump. Swing system troubleshooting covers the swing gearbox, control valve, travel control valve, and joystick control valve. There’s even a section for the accumulator and center joint (swivel). If you’re chasing a drift issue in the boom, you don’t guess – you follow the decision tree.

Another critical part is the travel motor chapter (Nabuko unit). It breaks down the travel motor (M3V270/160A), specifications, structure and function, disassembly and assembly, maintenance standards, and a cause-of-trouble chart. The reduction gear and brake valve (RBV-24DL4) get their own detailed procedures. The manual even tells you the special tools required – like the flow meter kit – so you can order them before you start the job.

Upper Structure Repairs: Cab, Counterweight, Fuel Tank

The upper structure section covers removal and installation of the cab, counterweight, fuel tank, and fuel transfer pump. The fuel transfer pump chapter includes troubleshooting steps and replacement of rotor and vane, rear cover, and armature. Swing bearing maintenance is spelled out with inspection intervals. The swing reduction gear (M105) has a full sequence: special tools, troubleshooting, removal, disassembly, reassembly, installation, and start-up procedures. If you’ve ever fought a binding swing gear because you skipped a step, you’ll appreciate the order here.

Related manuals for individual models: Daewoo Solar 130LC-V Workshop Manual, Daewoo Solar 170LC-V 2000 Workshop Manual, and Daewoo Solar 220LC-V Shop Manual are available separately if you need a dedicated volume for one machine.

Engine and Drive Train: Air-Conditioner System

The engine section includes a complete air-conditioner chapter. It covers refrigerant circulation, control panel, control specifications, temperature level control, air discharge path selection, and a system circuit diagram. The troubleshooting part helps you diagnose compressor or sensor issues without venting refrigerant. For the drive coupling (main pump), you get special tools and installation steps. The manual also references the Internal Combustion Engine for general theory, but the service procedures are what matter here – like how to align the coupling to avoid pump shaft damage.

Track Assembly and Lower Structure

Lower structure and chassis includes the track assembly chapter. It covers track tension adjustment, cleaning and inspection with wear limits, track shoes and links, front idler roller, lower roller, upper roller, and the track spring and track adjusting cylinder. The manual gives you the specific clearances and wear tolerances – not “replace if it looks worn.” You get actual measurements. And if you need to replace a track shoe, the removal sequence for the sprocket and idler is right there.

The manual also includes a section on the Manual Transmission general principles for the travel drive, but it’s the precise part numbers and torque values that save you phone calls to the dealer.

Does this manual cover the Solar 220N-V model?

Yes. Page 1 lists the Solar 220N-V with serial numbers 1001 and up. All sections in the manual apply to that model unless otherwise noted.

What torque specs are included?

The Standard Torques subsection gives you values for metric fasteners, U.S. fasteners, Type 8 phosphate coated hardware, hose clamps, split flanges, and torque wrench extension tools. Specific torque values for engine and hydraulic components are listed in their respective chapters.

Is this a factory OEM manual or a reprint?

It is a direct digital reproduction of the original Daewoo Heavy Industries & Machinery Ltd. publication from December 2001. Copyright 2001 Daewoo. No aftermarket editing or third-party content.

How many pages and what format?

582 pages in PDF format. The manual includes bookmarks for every chapter and subsection, plus a master table of contents. You can print what you need for the workbench.

You’ve got a machine that earns money when it runs. The difference between a repair that takes one shift and one that takes three is usually the documentation. Access the Factory Manual, get the correct pilot pressure, the right torque for your track adjuster bolts, and the full hydraulic schematic. Your service bay will thank you.
