Doosan D20GP D25GP D30GP-EX10-EX20 Lift Truck Parts Book SB1249E00

When a Doosan D20GP, D25GP or D30GP forklift is down, guessing at part numbers costs you days. This parts book (document number SB1249E00) gives you the factory-issued exploded views and part-numbered breakdowns for the entire truck – chassis, engine, powertrain, hydraulics, mast, carriage, and every factory option. It covers machines equipped with the Yanmar 4TNE98 Tier 3 diesel under model codes FDA0B (D20G), FDA0C (D25G), and FDA0D (D30G).

The catalog is organized by functional group so you can jump straight to the assembly you need. Every illustration is paired with a detailed parts table listing item number, part number, quantity, and description. Where a part has been superseded, the catalog shows the replacement part number and the serial-number break that applies.

How This Doosan Parts Book Is Organized

Every illustration in the catalog has a corresponding parts list. When a part name is indented, that component is part of the assembly above it. The abbreviation key near the front of the book tells you what each code means – for example, NS marks a non-serviceable part, C flags a changed part number, and Z indicates a component of an assembly that is not sold separately. Serial number breaks appear directly in the parts tables so you can confirm the correct part for your truck before ordering. The parts tables also carry a replacement/ICA column that points to the current part number when a part has been superseded.

Why This Doosan Parts Book Belongs in Your Shop

Doosan D20GP, D25GP and D30GP lift trucks are workhorses, and like any workhorse they need parts. Ordering the wrong filter, seal kit, or hydraulic cylinder because you guessed at a part number wastes days of downtime. With this parts book you can identify the exact part number for any serviceable component on the truck, see how assemblies go together before you take them apart, check serial-number breaks to make sure the part you order fits your machine, cross-reference superseded part numbers to the current replacement, and order the right seal kit, gasket set, or bearing the first time. You can plan rebuilds of the transmission, drive axle, mast cylinders, and brake assemblies, and find every factory option part number in one place.
