Doosan DL420 Wheel Loader Illustrated Parts Catalogue – June 2010 English/French Edition

Description

This Doosan DL420 Illustrated Parts Catalogue is the bilingual English/French 2nd Edition parts reference published for the DL420 wheel loader and dated June 01, 2010. Across 548 pages it maps the entire machine – engine assembly, chassis frame, front loader equipment, transmission, axles, hydraulics, electrical system, cabin and factory options – using numbered exploded figures tied to parts lists, so every component can be identified, cross-referenced and ordered by its Doosan part number. It is a working parts catalogue rather than a repair guide: the goal of every figure is to put the correct component in your hand, with the correct quantity, the correct variant for your machine’s serial range, and the correct replacement number when an older part has been superseded.

How the Catalogue Is Organised

Every section opens with a figure number and a matching exploded illustration. Callouts on the drawing link directly to the parts table that follows, where the key number, Doosan part number, English description, French description and required quantity sit side by side. Where a part changed during production, the table adds serial-number breakpoints (for example 5001-5032 / 5033-, 5001-5039 / 5040-, 5001-5042 / 5043- and 5001-5045 / 5046-) so the correct variant is chosen for the machine on the bench. Superseded and replaceable part numbers are flagged in a dedicated column so an older casting or seal can be replaced with the number Doosan currently issues. Hardware – bolts, washers, O-rings, seals, grease nipples, clips and shims – is listed alongside the major castings, which means a small consumable and a complete assembly can both be ordered from the same figure without hunting through a separate fasteners catalogue.

Working Across the Whole Machine

Because the Doosan DL420 Illustrated Parts Catalogue runs from the cylinder block all the way through to the homologation decals, it serves as a single-source parts reference rather than a collection of loose section prints. The engine chapter alone resolves the full top and bottom end – liners, main and big-end bearings, head gasket, valve guides, injector sleeves, camshaft brackets, tappets, rocker arms and push rods – while the hydraulic chapter covers the open-centre control valve, remote control valves, steering and lift cylinders, the fan drive, the accumulator charging circuit and both front and rear axle brakes. The electrical and cabin sections name every relay, fuse rating, switch, rocker insert and harness, and the option chapter lists the factory-approved additions such as LIS, emergency steering, heater, CCTV and rotating beacon so a retrofit matches the published specification.

Serial-Number and Variant Handling

The DL420 was produced across several serial ranges and individual parts were revised as the machine evolved. Rather than force one part number onto a component that changed mid-production, the catalogue splits affected lines into serial-keyed columns. This is what makes the same catalogue usable on an older loader and a fresh unit in the same workshop: one lookup gives the correct variant, the replaceable-part flag shows when a newer number supersedes an older one, and parts that carried over unchanged between serial breaks are listed once with the applicable ranges shown in the Serial No. column.

Who Gets the Most from It

Independent workshops servicing Doosan wheel loaders use the DL420 parts catalogue to quote accurately, prepare rebuild jobs and cross-check a supplier’s invoice against the published number. Fleet maintenance teams keep it open at the parts counter to raise a correct order without calling the dealer. Rebuilders pulling a transmission coupling or an axle differential carrier work straight from the exploded figure so no shim, snap ring or O-ring is missed on reassembly. And because the layout is bilingual, both English- and French-speaking technicians can read the same figure without re-keying part names.

IMAGES PREVIEW

Holding this catalogue means a technician, workshop or fleet owner can identify the right component and the right part number the first time, without a trip to the dealer counter or a guess at a superseded reference. Use it to build accurate quotes, prepare rebuild jobs, cross-check a supplier’s quote or hand the correct number to a machinist or fabricator. The bilingual English/French layout keeps the same figure usable across both language workflows. Delivered as an instant PDF download after payment – no shipping, no waiting – readable on a laptop, tablet or phone in the workshop and printable for a bench copy whenever a page needs to travel with the job.
