Searches for "Doosan parts book" have real volume in Saudi Arabia — and near-zero competition answering them. Here is the practical version of what that book is, how to read it, and how to get correct parts without owning a dealer terminal.

Doosan Model Codes in Two Minutes

**DX225LCA-2** — DX marks the excavator line; 225 the ~22-ton class; LCA the undercarriage/market variant; -2 the generation

**DL300-5** — DL wheel loaders; 300 the size class; -5 the generation

**DX55/DX62R** — minis; the R means reduced tail swing, which changes counterweight and slew parts

Older machines may carry Solar-series names (S225LC-V, S340LC-V) — these have their own parts books, and many components carried forward into early DX models with the same part numbers.

The Two Plates That Matter

**Machine serial plate** — on the frame near the cab. Gives the model code and serial that select the correct parts book and serial range

**Engine plate** — on the block. Doosan machines run DL06/DL08 Doosan diesels, and some variants use other engines. Engine parts are ordered off the engine model and serial, not the machine model

Photograph both. A parts request with two plate photos gets quoted in hours; one with "DX225, the pump is leaking" starts a long conversation.

How the Parts Book Is Organized

Doosan parts books group by system — engine, hydraulic, undercarriage, electrical, attachments — then by assembly diagrams with numbered callouts. Each callout maps to a part number and quantity. Two useful habits:

**Order by assembly, not by single part.** If a hydraulic pump seal failed at 9,000 hours, the parts book shows the full seal kit — replacing all of it costs little more and avoids opening the pump twice

**Check effectivity ranges.** Like Komatsu, Doosan applies changes at serial breaks; the book states which serials each part number covers

The Develon Wrinkle

Since the 2023 rebrand to Develon, new books carry the new logo — but part numbering is continuous. A DX225 part number from a Doosan-era book remains valid. Do not pay a premium for "Develon parts" that are the same items in a new box.

HESP maintains Doosan/Develon parts references for the DX and DL series common in Saudi Arabia and stocks fast-moving filters, seals, and undercarriage in Riyadh. Send your plate photos and part request — we confirm against the book before we quote.
