Doosan Solar 340LC-V 2002 Workshop Manual – 656 Pages of Factory Specs

You got a Solar 340LC-V in your bay? Don’t touch that machine until you have the Doosan Solar 340LC-V 2002 Workshop Manual open on your bench. I’ve seen guys strip a counterweight bolt because they used a generic torque chart. That bolt alone costs $40 and a day of downtime. This manual is 656 pages of Daewoo (Doosan) factory print—no aftermarket rewriting, no lost data. It covers serial number 1001 and up, published May 2002. The safety section alone runs over 50 pages. On page 1 you’ll find the product label instructions—trim it out and stick it in the binder spine so you know exactly which revision you’re holding.

Working from memory on an excavator this size is like rebuilding a transmission blindfolded. You need the exact specs for the swing reduction gearbox, the fuel transfer pump, and the hydraulic system troubleshooting procedures. This manual has them all. The table of contents lists Safety, Specifications, General Maintenance, Upper Structure, Lower Structure and Chassis, Engine and Drive Train, and Hydraulics. Each section is numbered with a Daewoo part number (S0102000, S0202110K, etc.) so you can cross-reference bulletins.

Track Excavator Safety Essentials

Before you even start the engine, read the “Track Excavator Safety” chapter. It covers the signal words used with the safety alert symbol, the location of safety labels, and precautions for high-voltage cables. The manual explicitly warns about accumulator discharge, asbestos dust hazard prevention, and what to do when you find a hydraulic leak. There’s a whole subsection on “Precautions When Handling Fluids at High Temperature” that I’ve used more times than I want to admit. Safety isn’t a suggestion here—it’s written as a standard operating procedure. If you skip it, you’re gambling with your hands and your wallet.

Standard Torques: Get the Right Numbers

One of the first things I look for in any manual is the torque spec table. This one has “Standard Torques” under General Maintenance (section S0309000). You get torque values for standard metric fasteners, standard U.S. fasteners, Type 8 phosphate coated hardware, hose clamps, split flanges, and even torque wrench extension tool formulas. The section covers how to calculate torque multiplication when you’re using a crowsfoot or extension. Don’t guess—measure. On a machine this heavy, a loose hydraulic flange can blow a line and turn your shop into a slip-and-slide.

Upper Structure: Cab, Counterweight, and Fuel Tank

The Upper Structure section includes removal and installation procedures for the cab (S0402040K), counterweight (S0403050K), fuel tank (S0405130K), fuel transfer pump (S0405500), swing bearing (S0407000), and swing reduction gearbox (S0408030). Each procedure starts with a parts list and specifications. For the fuel tank, you get start-up procedures after installation—bleeding the air out of the system the correct way. I’ve seen guys crack injector lines because they thought “close enough” worked. It doesn’t. The manual gives you the step order and the required tool list. If you’re swapping a counterweight, pay attention to the warning for counterweight and front attachment removal—there’s a sequence that keeps the machine stable.

Hydraulic System Troubleshooting: Factory Testing Methods

The hydraulics chapter (S0702180K) covers troubleshooting, testing, and adjustment. It includes test conditions for travel speed, travel motor balance (steering deviation), swing speed, deceleration force, and cylinder performance. No aftermarket manual gives you those test parameters. The accumulator section (S0703010K) tells you how to discharge and recharge it safely. If you’ve ever had a high-pressure line burst in your face, you’ll appreciate the “Precautions with High Pressure Line, Tubes and Hoses” section. That’s the kind of detail that keeps you working tomorrow.

Who Needs This Manual?

If you own a Solar 340LC-V and do your own maintenance, this is your bible. Same if you’re a mobile heavy-equipment mechanic who can’t call the dealer every time a control valve sticks. The manual is written for someone who can read a specification sheet and follow a sequence—not for someone looking for “easy fix” shortcuts. Beginner? That’s fine if you’re willing to learn. The manual’s language is direct, and the diagrams are clear. But you need to respect the safety warnings. I’ve trained a few young techs with this manual, and they learn faster because they aren’t fighting bad data.

Pair this with the DOOSAN DX140W/DX160W Shop Manual if you also work on those models. The DH130W Shop Manual 2023-7049 covers a different wheeled excavator but same generation of hydraulics. For engine-specific specs, grab the Doosan Excavator S170 Engine Specifications. And if you’re maintaining other equipment with a Manual Transmission, don’t use excavator specs for that—different world. The same goes for the Manual Transmission video series I recommend to my guys—watch it after you’ve got the hydraulics down.

OEM vs Aftermarket: Why This One Works

This is a genuine Daewoo (Doosan) publication, not a scanned third-party reprint that lost half the resolution. The original PDF is 656 pages with bookmarks for every section—Safety, Specifications, General Maintenance, Upper Structure, Lower Structure, Engine & Drive Train, Hydraulics. I’ve compared aftermarket versions that leave out the “Asbestos Dust Hazard Prevention” page or the “Torque Values for Split Flanges” table. That missing data kills jobs. This manual gives you the exact factory procedures Daewoo released in 2002. No errors introduced by a typist in another country. The serial number coverage (1001 and up) matches the machine’s plate—no guesswork.

Frequently Asked Questions

Does this manual cover serial numbers below 1001?

No. It covers 1001 and up.

I need torque specs for the swing reduction gearbox bolts. Where are they?

The standard torque table in section S0309000 gives you the values for the metric fasteners used on the swing reduction gearbox. But for specific joint torque (like the gearbox-to-frame bolts), you also need the assembly procedure in section S0408030. The manual does not list a separate torque value for every single bolt—it expects you to use the standard table unless a note calls out a different spec. I’ve had to review that section three times on one machine because the bolt grade changed between production runs. The manual includes notes for “Type 8 Phosphate Coated Hardware” which is common on swing drivetrains. If you’re still unsure, check the machine’s serial number against the revision date; early 1001 machines used a different bolt pattern than later ones. That kind of detail is why you buy the factory manual instead of a $20 CD from eBay.

You need the factory data to keep that excavator running without surprises. Access the Factory Manual now and put it on your shop tablet or print the pages you need for the job. I keep mine grease-stained and dog-eared—it’s the only way to work.
