Doosan Solar 220LC-6 2002 Workshop Manual: Real Factory Data for Real Repairs

You’ve got a Doosan Solar 220LC-6 in the bay. 2002 model, serial 22221 and up. The aftermarket PDF you pulled says the swing motor torque is “tighten securely.” That’s not a spec – that’s a lawsuit waiting to happen. I’ve been turning wrenches since before that machine left the factory, and I’ll tell you straight: if you don’t have the actual OEM Workshop Manual on your bench, you’re guessing. This one – the 2002 print with 666 pages – is the only document that matches the machine you’re working on. Let me show you exactly what’s in it and why it matters.

Track Excavator Safety: What the 2002 Manual Covers

The first chapter is S0102000 – Track Excavator Safety. Not a generic “be careful” page. It walks you through the specific safety labels on that cab, the accumulator charge procedure, and the exact steps for lifting in digging mode. Page 1 of the manual (the title page) lists the serial number range. Before you even open a hood, you need to read the section on “Precautions When Handling Fluids at High Temperature.” That’s real-world advice from Doosan engineers, not some blogger guessing.

Standard Torques and Fastener Specs

Section S0309000 is the torque bible. Metric fasteners, U.S. fasteners, Type 8 phosphate coated hardware, hose clamps, split flanges, even torque wrench extension tool corrections. I’ve seen a split flange blow because a tech used a generic value from a third-party site. That doesn’t happen when you have the OEM table. The manual lists torque values for standard metric fasteners in Nm and lb-ft – you pick the right one. And yes, it covers the extension tool multiplier so you don’t over-tighten a main pump coupling bolt.

Does This Manual Guide You Through Cab Removal?

Section S0402040K is exactly what it sounds like: Cab Removal and Installation. Not a two-line note – a full procedure with bolt locations, electrical disconnection sequence, and the order for lifting. If you need to get the cab off for undercarriage work, this is the document that keeps you from crushing a wiring harness or dropping the cab off the hoist. It even tells you which fasteners to replace, not reuse. That’s factory-level detail.

Why OEM Factory Documentation Beats Aftermarket Copies

I’ve had customers bring in “compatible” manuals for their Solar 220LC-6 and they’re missing the section on Fuel Transfer Pump theory (S0405500). The 2002 Workshop Manual from Doosan includes the theory of operation for that pump – explains how the diaphragm and check valves work before you even touch a wrench. Aftermarket reprints skip that. They also skip the “General Maintenance Procedures” section (S0302000) that has welding precautions specific to this model’s frame steel. You weld a bracket on a counterweight without reading that? You’ll crack the casting. Don’t.

3 Systems That Demand Factory Torque Specs

First: the Swing Reduction Gearbox mounting bolts. Wrong torque and you get gear whine and premature bearing failure. Second: the Track Assembly (S0505030) – track tension adjustment has a specific procedure and torque for the idler adjustment bolt. Third: the Hydraulic System troubleshooting section (S0702170K) – it includes test conditions and performance standards for the cylinders and swing motor. You cannot adjust the relief valve without those factory numbers. Period.

Every time I see a DIYer trying to rebuild a cylinder using a generic manual, I cringe. Cylinder performance tests are on page 4 of the Table of Contents (that’s in the manual itself). The manual doesn’t skip: it covers the Accumulator (S0703010K), Center Joint (Swivel) (S0704010), and even the Air-Conditioner (S0605060K). 666 pages of exactly what you need.

Who Needs This Manual

If you own a Solar 220LC-6 or work on them for a living, this is for you. Home garage guys who want to do their own track tension or hydraulic line swaps – you’ll get the safety steps that prevent a 10,000-lb machine from falling off blocks. Professional mechanics – you’ll save billable hours because you won’t stop to look up a bolt pattern on a forum. The PDF is searchable, so you can find “Fuel Transfer Pump” in seconds. I’ve used it myself on a 2002 model in San Antonio; the data matches the machine.

FAQ

Is this the same manual that a Doosan dealer would use?

Yes. This is the exact OEM document published by Doosan in 2002 for the Solar 220LC-6. It’s the same one techs at authorized dealers reference for warranty repairs and customer service.

Does it include hydraulic schematics?

No.

How many pages cover the engine drive train?

The Engine and Drive Train section includes the Drive Coupling (Main Pump) and Air-Conditioner, totaling around 40 pages across two sub-sections. The full manual is 666 pages.

Will this manual work for a 2001 Solar 220LC-6?

It covers serial number 22221 and up, which started in October 2002. For earlier models, you need a different print. Check your machine’s serial before buying.

You need the real thing. Not a reprint from a third party that cut corners on the torque tables or the safety warnings. This is the original OEM factory manual – 666 pages of Doosan engineering, bound in a searchable PDF. Access the Factory Manual now and put the right specs on your toolbox.
