Daewoo Mega 400-V 2001 Workshop Manual

Aftermarket manuals will get you in trouble. They skip the safety warnings from the factory, print torque specs that don’t match the fasteners, and leave out the error code tables that keep a ZF transmission from locking you out. The Daewoo Mega 400-V 2001 Workshop Manual is a 618-page OEM document printed by Daewoo for serial number 1001 and up. That factory binder tells you exactly how to service this wheel loader without guessing. Page 1 of the manual states the serial number coverage and warns that Daewoo may make improvements without updating previous manuals. That is important if you are working on an early production machine. Page 3 starts the table of contents, listing every section from Safety through Hydraulics. You do not get that level of detail from a third-party copy.

For a direct copy of this specific factory document, see the order page for the Daewoo Mega 400-V Shop Manual.

Safety Section: Not Optional

The safety section (S0103010K) covers everything from work-site precautions like avoiding high-voltage cables, using solid support blocking, digging beneath overhangs, and sloping terrain caution, to operation rules like operating only from the operator’s station, never using ether starting aids, mounting and dismounting safely, and observing general safety rules. It also includes equipment requirements such as seat belts, window glass breaking tool, fire extinguisher, and periodic replacement of safety-critical parts and hydraulic cylinder seals. That level of detail is absent from aftermarket reprints, which often skip the safety warnings entirely to save paper. If you are working on this machine, you need those warnings because a wheel loader can kill you if you ignore a pinch point or a pressurized hydraulic line.

Standard Torques Section

The Standard Torques section (S0309000) covers torque values for standard metric fasteners, standard U.S. fasteners, Type 8 phosphate coated hardware, hose clamps, split flanges, and torque wrench extension tools. If you are replacing a hydraulic line or a flange bolt, you need these numbers. Aftermarket manuals copy torque values from other machines and hope they fit. This manual gives you the factory spec for every fastener on the Mega 400-V.

Transmission Error Codes (ZF)

Transmission Error Codes (ZF) section (S0607900C) is a separate chapter for diagnosing the ZF transmission. Without the error code table, you will be swapping parts until you hit the problem. That costs time and money. If you also service other Daewoo buses, the Daewoo SOLAR 010 1997 Workshop Manual – OEM Bus Repair Specs covers similar ZF transmission error codes.

Does This Manual Cover the Fuel Transfer Pump?

Yes. Section S0405500 under Upper Structure covers fuel transfer pump removal and installation. That is a specific component that aftermarket manuals often gloss over or describe generically. You get the step-by-step with part numbers and torque values for the pump mounting bolts.

7 Systems Covered in the TOC

According to the table of contents, the manual covers seven major systems: Safety, Specifications, General Maintenance, Upper Structure, Lower Structure and Chassis, Engine and Drive Train, and Hydraulics. That includes front and rear axle, air-conditioner, ZF transmission, accumulator, cylinders, fan drive hydraulic motor, and main pump. The engine section relies on the Internal Combustion Engine fundamentals documented by the manufacturer. The ZF transmission error codes are based on the Manual Transmission diagnostics used by Daewoo.

Hydraulic System Precautions: Factory Procedure

The General Maintenance section includes specific precautions for hydraulic system service: cleanliness, oil leak detection, and the fact that high pressure hydraulic lines can store a great deal of energy. You must depressurize before opening any line. The manual tells you how. For heavy-duty bus models, the Daewoo Solar 210W-V Workshop Manual – OEM Factory Shop Manual for Heavy-Duty Bus provides the same factory rigor.

What torque values are included?

Standard torques for metric and U.S. fasteners, hose clamps, split flanges, and extension tools are in the Standard Torques section.

How many pages does this manual have?

The Daewoo Mega 400-V 2001 Workshop Manual has 618 pages, but you need to know that page count alone doesn’t tell you the coverage. This manual includes full sections on safety procedures, specification sheets for the entire machine, general maintenance with standard torque tables, upper structure removal and installation, lower structure and chassis articulation joint service, engine and drive train including front and rear axle, air-conditioner, ZF transmission with error codes, and hydraulics covering accumulator, cylinders, fan drive motor, and main pump. That is a lot of content for a bus.
