Doosan D20G D25G D30G 34KW Forklift Parts Manual PDF

Description

Doosan D20G / D25G / D30G 34KW Forklift Parts Manual

Tracking down the correct part number for a Doosan counterbalance truck usually ends in one of two places: a phone call, or a parts book like this one. This Doosan D20G D25G D30G 34KW forklift parts manual collects the complete illustrated parts catalogue for the D20G, D25G and D30G series into a single PDF, covering the trucks built with the Yanmar 4TNE94L 34KW diesel engine. Every group is drawn, every serviceable item is numbered, and every number is listed with its part name and the quantity required per assembly.

The catalogue is written for the parts counter and the workshop floor alike. Each illustration carries a figure number and a group number, and each numbered callout in the drawing maps to a line in the parts list printed with it, so a half-remembered bracket, a snapped lever or a worn bushing can be traced from the picture to the part number without guesswork.

Read end to end, the catalogue describes the whole truck rather than a single system. The chassis section handles the steering axle, frame, hood, cooling and electrical groups; the powertrain section covers the transmission, clutch pack, differential, drive axle and wheel brakes; and the mast and implement sections break down lift and tilt hydraulics, hose and line routing, side shifters, carriages and forks. Because the engine is treated as its own section with the Yanmar 4TNE94L broken down into block, head, camshaft, crankshaft, lubrication, cooling, fuel injection and starting circuits, a buyer working on the diesel side of the truck gets the same level of detail as someone replacing a mast hose.

Capacity-Specific Listings

Where the 2.0/2.5 Ton and 3.0 Ton trucks use different parts, the book splits them rather than merging them. You will see this most clearly in the frame groups, the drive axle groups, the wheel brake assemblies, the tilt cylinder assemblies, the side shifter groups and the tire and wheel arrangements, which are listed separately for each capacity class, including the dual-tire and solid-tire variants.

How the Parts Lists Are Organised

Each figure is captioned with its figure number, group name and group number. The parts list beneath it gives the item number, part number, quantity, part name and description. Where an item is indented in the list, it forms part of the serviceable item above it, so assemblies and their components are easy to tell apart. The book also uses a standard set of abbreviations and markers throughout: items marked as not part of the group, parts used as required, changed part numbers, parts ordered by the metre or centimetre or inch, metric parts, separate illustrations, components of an assembly that are not available independently, parts contained in a service kit, non-service parts, and deleted items. Locations are shown as a separate location chart divided into four parts.

Why This Parts Book Pays For Itself

Ordering the wrong component on a lift truck is expensive in both directions: the part does not fit, and the truck sits idle while the correct one is sourced. Working from an illustrated Doosan D20G D25G D30G 34KW forklift parts manual removes that risk. Every number in the book is tied to a drawing of where it belongs, so you can confirm you are looking at the right variant for a 2.0 Ton, 2.5 Ton or 3.0 Ton truck, the right side for a left or right hand wheel brake or tilt cylinder, and the right option level for a truck with or without a cabin, overhead guard or side shifter.

It also makes rebuilds practical rather than hopeful. Seal kits, gasket sets, brake springs, cups, pistons, bearings, bushings and shims are all listed individually inside their assemblies, so a cylinder or brake rebuild can be planned component by component instead of replacing an entire unit. The part number index at the back of the book works in reverse as well: if you already have a number in hand, you can look it up and find exactly which figure and which item it belongs to before ordering.
