Doosan DX 255 LC Parts Catalog – 594 Pages of Factory Part Numbers

If you’re ordering parts for a Doosan DX 255 LC and guessing at the number, you’re wasting time and money. I’ve seen too many guys slap on a seal kit that almost fits, then chase leaks for three days. This Doosan DX 255 LC Parts Catalog – 594 pages – gives you the exact factory numbers so you don’t play roulette with your rebuild. Straight from Doosan themselves, not some third-party cross-reference that might be off by a digit.

Filter Service Intervals: Page 3 Data You Need

The catalog includes a filter table right on page 3. Engine oil filter (65.05510-5032) at 500 hours, fuel filter (65.12503-5026) at 500 hours, air cleaner inner element (474-00039) at 2000 hours. You get the part numbers and the service intervals in one place. No digging through a separate maintenance guide. If you’re running a breaker, the optional breaker filter (474-00046) gets changed every 250 hours – that’s in there too. Write it on the cab wall.

Under Carriage Parts: Sprockets, Rollers, and Track Link Specs

Under carriage components are listed with full part numbers: idler K1011790, upper roller 270-00064A, lower roller K1011713A, track spring K1010512A, sprocket K1010542. Track link without shoe is K1011519 (600G pitch), and you can order track shoe assemblies K1011514 for 600G or individual shoes for 700G, 800G, 900G. The parts catalog breaks it down by grouser width so you get the right shoe for your ground conditions. Mixing up a 600G and 700G shoe will cost you track life.

Seal Kits and Gasket Sets: Why OEM Part Numbers Matter

Seal kits for boom, arm, bucket, track spring, center joint – all listed: boom seal kit K9004899, main pump K9004882, swing motor K9004885, travel motor 2401-9082K, control valve 420-00295KT. Engine gasket kits too: top overhaul 65.99605-8042, all overhaul 65.99601-8071. You order the wrong seal kit and the gland won’t seat – then you’re pulling the cylinder back off. A factory parts catalog eliminates that risk.

How to Order Parts: What the Foreword Tells You

Page 5 has a foreword with ordering instructions. You need model (DX255LC), machine serial number (from bed frame nameplate – example HEBFO-OOOO), engine serial number (from cylinder block), part number, description, quantity. I’ve had parts guys reject orders because the serial number format was off. The catalog shows you exactly where to find each number.

Why a Factory Parts Catalog Beats Aftermarket Cross-References

Aftermarket catalogs often group parts by generic size and skip the revision letters. Doosan revises part numbers – for instance, the battery relay 2544-9024 might supersede an older number. The factory catalog captures that. Plus you get the full electrical section with fuse ratings (10A, 15A, 20A, 30A, fusible link 27A) and relays. Try finding a fusible link amperage in a third-party book. You won’t. That’s why I keep a factory parts catalog on the bench.

Your time is billable. Stop chasing numbers. Access the Factory Manual and get the right Doosan DX 255 LC parts the first time.

Does this parts catalog include torque specs for the DX 255 LC?

No. This is a parts catalog, not a service manual. Torque values are in the service manual. The parts catalog gives you the correct bolt and seal part numbers, but you still need the service manual for tightening sequences and torque values.

Can I use this catalog for ordering electrical parts like bulbs and fuses?

Yes. Bulb part numbers are listed: 24V 2W (515-00012A) for instrument lights, halogen 24V 75/70W (2515-1016D4) for headlights, fuses from 10A to 30A, and relays including battery relay (2544-9024). Use the machine serial number to verify the exact revision.
