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

If you are pulling wrenches on a Daewoo Solar 130LC-V, Solar 170LC-V, Solar 220LC-V, Solar 250LC-V, or Solar 220N-V from 2001, you have already found out that aftermarket manuals leave you hunting for torque values that don’t exist. This is the factory Service Manual – 601 pages of what Daewoo actually wrote for the guys who built these machines. I have been in the shop for 28 years. I have seen one too many track adjuster come off because someone used a generic spec. That ends here.

Safety and Track Excavator Procedures

The front section of this manual – roughly the first 22 pages – is all safety. Not the generic “wear safety glasses” junk you get in a Hanes manual. Daewoo spells out lifting precautions for digging mode, sling capacities, shipping tie-downs. Page numbers inside the TOC let you jump straight to Summary of Safety Precautions for Lifting in Digging Mode. If you are swapping a counterweight or pulling the cab, that section keeps you from crushing your foot. I make every new kid in my bay read the safety pages before he touches a hydro line. Work site precautions, location of labels – it is all in there. No filler.

Specifications for Solar 470LC-V (and How It Applies to Your Models)

You might wonder why a 2001 manual for series V machines includes specs for the bigger 470. Because the engines, pumps, and swing gear share design architecture. The chapter “General Specifications” lists engine performance curves per KS-R1004 standard, component locations, and working range dimensions. Need the charge pressure for the main pump on a Solar 220LC-V? The test procedure is the same platform. Do not assume a spec from a Cat 320 will work – it won’t. Stick to the factory data. That is what keeps seals from blowing out on a Friday afternoon.

Standard Torques: What You Actually Need

General Maintenance includes the Standard Torques section. Metric fasteners, U.S. fasteners, Type 8 phosphate coated hardware, hose clamps, split flanges, and torque wrench extension tools. That last one – extension tools – is something most aftermarket PDFs ignore. If you put a crows-foot on a torque wrench, the value changes. Daewoo tells you the correction factor. I have used those numbers on Solar 170LC-V track frame bolts more times than I can count. 601 pages means no shortcuts.

Upper Structure and Lower Chassis: Disassembly Without Guessing

The manual breaks down cab removal, counterweight, fuel tank, fuel transfer pump, swing bearing, and swing reduction gearbox. Each procedure lists required special tools – for example, for the swing gearbox removal you need a puller set and a dial indicator. The Cleaning and Inspection sub-sections give wear limits and tolerances. Track assembly, front idler roller, track tension adjustment – all in the Lower Structure chapter. Do not try to adjust track tension on a Solar 220N-V by feel. The factory spec is in the manual. I have watched guys overtighten and wipe out idler seals in a week. Use the book.

Hydraulics: Rexroth Main Pump, Swing Motor, Travel Motor

The hydraulic chapter runs about a third of the total pages. It covers troubleshooting, testing, and adjustment for the Rexroth main pump, swing motor, travel motor (A6V160HD with gearbox), cylinders, center joint (swivel), and accumulator. The procedural troubleshooting baseline recommendations tell you how to isolate pilot pressure problems vs. pump input power control issues. There is a full flow meter kit installation procedure. Want to know the rebuild steps for the travel motor speed reduction gearbox? The manual gives disassembly, cleaning, wear limits, and reassembly in that order. No skipping steps.

Does This Manual Cover the Engine and Drive Train?

Yes – the Engine and Drive Train section includes the air-conditioner system (refrigerant circulation, circuit diagram, troubleshooting) and the main pump drive coupling installation. The engine itself is covered across multiple chapters: removal, installation, performance curves. If you are swapping a powerplant on a Solar 250LC-V, the wiring diagrams and torque specs for the flywheel housing are on the pages referenced in the table of contents. Aftermarket sources like Internal Combustion Engine articles can give general theory, but for the specific bolt pattern on a Daewoo diesel, you need the OEM manual.

3 Reasons to Choose OEM Documentation Over Aftermarket Reprints

Number one: torque values. Aftermarket reprints often copy from a different year or model and skip the Torque Values for Split Flanges page. Number two: safety warnings specific to the daewoo track excavator design – aftermarket editors cut those to save space. Number three: hydraulic troubleshooting logic is proprietary; daewoo includes pump control module removal and control housing procedures that no generic book has. I have seen a three-hour job turn into a week because a tech trusted a $20 CD-ROM. Spend the money on the real thing once.

Who Should Buy This Manual?

If you own or maintain any of the Solar series V excavators – 130LC-V, 170LC-V, 220LC-V, 250LC-V, or 220N-V – and you plan to do your own repairs, this is the manual. Home-garage enthusiasts who are tackling a swing gearbox rebuild or a track adjuster replacement will find the step-by-step procedures with exact tolerances. Beginners, read the safety section first and then follow the Cleaning and Inspection checklists – they tell you when a part is scrap. Professional mechanics, this is the document to hand a green helper so he does not strip a split flange bolt.

What torque values are listed for the swing gearbox mounting bolts?

The standard torque section includes values for metric fasteners up to M30. For the swing gearbox, refer to the general torque table – Daewoo does not repeat those numbers in the specific procedure. Use the chart on the torque page. If you lose that page, you are guessing.

Does this manual cover the fuel transfer pump armature replacement?

Yes. The upper structure chapter has a dedicated fuel transfer pump subsection with replacement procedures for rotor, vane, rear cover, and armature.

I have been in this trade long enough to know that the difference between a job done once and a job done twice is having the factory spec on the bench next to you. This 2001 Daewoo Solar service manual gives you 601 pages of verified OEM data. Access the Factory Manual from AutoRepairManuals and get back to turning wrenches with the right numbers.
