Daewoo G20S-2, G25S-2, G30S-2 Parts Catalog

If you’ve ever been stuck with a lift truck down because the parts counter sent you the wrong hydraulic fitting or a seal that doesn’t fit, you know the cost of guesswork. That’s why you need the Daewoo G20S-2, G25S-2, G30S-2 Parts Catalog — the actual factory document, not some aftermarket rehash. This book runs 432 pages, covers every serviceable part on these three models, and comes straight from Daewoo’s engineering files. It lists part numbers, quantities, illustrations, and the correct assemblies so you order the right piece the first time.

You’re not throwing money at a dealer’s parts department hoping they guess right. You’re handing them the exact number from page 73 of this catalog. That’s the difference between a 10-minute fix and a half-day wait for a return.

What This Parts Catalog Actually Covers

Daewoo built the G20S-2, G25S-2, and G30S-2 as a family — same frame architecture, different lift capacities. This catalog includes chassis, mast, attachments, and optional accessories. The foreword on page 3 states clearly: it lists all serviceable parts for these models. You get mast types covered — GS Type (figures 15.01 to 16.21) and Mast Type 1 (figures 12.03 to 13.38). If your truck has a two-stage or three-stage mast, the correct part numbers are inside.

The catalog uses a group-and-assembly layout. Each illustration shows the standard components and any attachments. The caption under each picture gives the group part number and name. Inside the illustration, a parts list identifies every individual part. When a part name is indented, it means that item is a sub-component of the major assembly above it. You won’t have to guess which bolt goes with which bracket.

432 Pages of Factory Part Numbers

Four hundred thirty-two pages. That’s not a quick-reference card; it’s a comprehensive breakdown of everything from the engine block to the steering cylinder. Every part number is an OEM Daewoo number. You won’t see cross-references to generic aftermarket numbers — those are guesses. This catalog gives you the exact digits the factory uses. If the part has been superseded, the catalog notes changes (abbreviation “C” indicates a change). If you see “Z” in the list, that part is not serviced separately — you order the whole assembly.

The table of abbreviations on page 4 explains every code. For example, “D” means order by meter (for hoses), “R” means a repair part may be available, and “X” indicates a major component exchange. Learn those codes and you’ll stop ordering pieces that don’t exist individually.

How to Identify Your Lift Truck Correctly

Before you start flipping pages, you need to know your machine’s model name and serial number. Daewoo stamps these on an identification plate mounted on the cover or top cover. If that plate is missing or unreadable, look for the decal on the top cover and the serial number stamped on the frame. Page 3 of the foreword drills this into you: “Daewoo dealers or parts depot need this information to determine which components were included on the machine when it was assembled at the factory.” I’ve seen guys order a water pump for a G25S-2 that didn’t match because they guessed the serial number range. Don’t be that guy.

Serial number ranges are printed at the top of the first page: EM009-00001-01278, EM010-00001-02497, EM011-00001-00948, EM012-00001-09723. These brackets tell you which revision of the truck you have. Match your serial number to the correct range before ordering.

Ordering Parts: The Right Way

When you call your dealer, have this ready: model name, serial number, quantity, part number, and part name. The manual says it on page 3: “If in doubt about the part number, please provide your dealer with a complete description of the needed item.” That’s not an excuse to skip looking it up — it’s a fallback. Look up the number yourself. The illustrations are labeled clearly. Cross-reference with the parts list on the same page. If you see an indented part, click down the hierarchy until you find the exact fastener or seal.

A common mistake: ordering the whole mast assembly when you only need a lift chain roller. The catalog shows the roller as a separate item under the mast group. You save hundreds of dollars by ordering the specific piece. And since the catalog is OEM, you won’t get a roller that’s a millimeter too small.

Why OEM Beats Aftermarket for Parts Identification

Aftermarket parts catalogs are often scanned from old copies, re-labeled, or missing revision notes. This Daewoo document is the original factory file. It includes the “UNNOTICED REVISION OF TRUCK” warning: continuing product improvement may cause changes not yet in this book. That honesty is valuable — it tells you to check for supersessions. No aftermarket reprint includes that nuance. If you’re rebuilding a G20S-2 that’s been in service for years, having the original part numbers means you can trace the revision history through the dealer.

The catalog also references the Internal Combustion Engine layout — engine components are grouped in their own section. For electrical diagnostics, you’d pair this with a wiring diagram (not included here) but for part ordering, this is your single source of truth.

FAQ: Daewoo G20S-2, G25S-2, G30S-2 Parts Catalog

Does this catalog include torque specifications for assembly?

No. This is a parts catalog — it lists part numbers and illustrations, not service procedures or torque values. You need a separate service manual for tightening specs. But knowing the exact part number ensures you’re using the correct bolt grade.

Can I use this to rebuild a mast from scratch?

Yes, if you have the service manual alongside. The parts catalog shows every mast component (rollers, chains, hoses, seals) with OEM numbers. Order them all, then assemble using the factory service procedure.

What if my machine has a serial number outside the listed ranges?

Contact a Daewoo dealer with your serial number. The catalog covers EM009 through EM012 ranges for these three models. Later production runs may have been updated. The foreword warns about unnoticed revisions, so always verify.

How do I identify which mast type I have?

Look at the mast data plate or measure the lift height. The catalog includes separate sections for GS Type (fig.15.01–16.21) and Type 1 (fig.12.03–13.38). Compare your mast’s cylinder arrangement and chain configuration to the illustrations. If you’re still unsure, the serial number on the frame should match the mast build.

If you want to stop ordering the wrong parts and start fixing trucks, get this factory document on your bench. Access the Factory Manual from AutoRepairManuals – it’s the same 432-page PDF the dealers use. One copy in the shop, one on your tablet, and you’ll never waste another shift chasing a mismatched part.
