Doosan M400-V Parts Catalog – 636 Pages of Factory Part Numbers & Service Codes

If you’ve ever ordered a seal kit for a Doosan wheel loader and got the wrong bore size because you trusted a third‑party cross‑reference, you know the pain. That part holds up the whole job, the machine sits, and the customer stares at you. This Doosan M400-V Parts Catalog fixes that. It’s the same 636‑page document the dealer uses, straight from Doosan, covering serial number 3001 and up. No aftermarket translations, no re‑typed tables with OCR errors. You get the exact part numbers, quantities, and service codes that match the machine on your bay.

Filter Service Intervals – What Page 3 Tells You

Page 3 of the catalog lists every filter on the M400‑V, with the OEM part number and the recommended replacement interval in hours. Engine oil filter (65.05910‑5020B) every 500 hours. Fuel filter (65.12500‑016B) every 500 hours. The inner air cleaner element (474‑00007) goes at 1000 hours, outer element (474‑00006) at 1500. They even give you the T/M filter (474‑00021) at 1500 hours and the air breather element (K1029257) at 1000. If you’re still guessing which filter to buy, this catalog ends the guesswork. Use the part number, not the cross‑reference from the parts store.

7 Systems Covered – From Belts to Seal Kits

Beyond filters, the catalog breaks down every system: belts (aircon belt 2106‑1019D20, fan belt 65.96801‑0144A), bulbs (halogen 24V 75/70W 2515‑1022D1, 24V 21W 8864221H), battery and fuses (10A to 30A with part numbers 2527‑1016 through 2527‑1020, fusible link 27A 2527‑1023A, relay 2544‑9033), seal kits for steering (4713‑1131B), lift (4713‑1132B), and bucket (4713‑1183C). Engine gasket kits for a full overhaul: 440‑00139KT, 440‑00138KT, 440‑001358KT. Every part has a key number that links to the exploded illustration on the facing page.

How to Order Parts – The Foreword’s Rules

Flip to the foreword. It tells you exactly what Doosan needs when you call: model (M400‑V), machine serial number (starts HLSY‑), engine serial number (DE12TIA for Tier I, DE12T1S for Tier II), part number (e.g., 401‑00156), and quantity. Ignore that and you’ll get the wrong pump body. The catalog also explains the service codes in the right‑hand column: B means the part needs work before installation, D means it’s not serviceable alone (you buy the whole assembly), K means it’s in a service kit, M means you buy mating parts together, R means quantity changes depending on the machine configuration. That’s the kind of detail you won’t find in a generic parts PDF.

Who Needs This Manual?

If you maintain a Doosan M400‑V wheel loader in a fleet or fix them for a living, this catalog is your parts bible. Home‑garage guys who bought a used loader at auction – you’re the ones who get burned by aftermarket lists that don’t know the difference between a Tier I and Tier II engine. With this catalog, you can order the correct seal kit, filter, or gasket set without tearing into the machine first. It’s also the right reference for shop owners who want techs to stop wasting billable hours hunting for part numbers online.

Source Validity – OEM vs Aftermarket

This is an original Doosan publication – part number 021‑00082GEF, printed for the M400‑V with serial 3001 and up. The file is a true PDF reproduction of the dealer‑level parts list. Compare that to a scanned third‑party reprint where the part numbers get smeared and the key numbers don’t align with the illustrations. I’ve rebuilt enough Deutz and Doosan power units to know that one wrong digit in a bearing number kills an afternoon. This catalog eliminates that. It’s not a reprint; it’s the factory file. Want more examples of OEM precision? Look at the DOOSAN DX140LC Parts Catalog Contents – Section: Hydraulic Parts (Section 4Xxx) for the same level of exploded diagram accuracy. Outside this shop, you can also find background on how these engines work at Internal Combustion Engine on Wikipedia or the broader Automotive Industry Overview – but for the M400‑V, this catalog is the only source you should trust.

FAQ

Does this parts catalog include torque specs for reassembly?

No. This is a parts list, not a repair manual. It gives part numbers, quantities, and service codes. For torque values, you need the factory service manual for the M400‑V.

How do I identify which engine serial number prefix applies to my machine?

Doosan M400‑V loaders use the DE12TIA engine (Tier I) or DE12T1S (Tier II). The serial number is stamped on the cylinder block, right side, near the starter. Look for the prefix DE12TIA or DE12T1S before the six‑digit number. The parts catalog lists different gasket kits for each tier – page 4 shows 65.99605‑8028 for one and 65.99601‑8043 for the other. If you input the wrong one, you’ll get a gasket that doesn’t fit the piston cooling jet or the injection pump base. The foreword also tells you to quote the engine serial number when ordering engine parts like the overhaul gasket kit (440‑00139KT). Match that prefix, and you’ll get the right kit. If the serial is unreadable, pull the valve cover and look for a stamped tag on the rocker base – it’s often visible without a mirror.

Stop chasing wrong part numbers and ordering twice. Access the Factory Manual now and keep it on your shop tablet or printed in the binder next to the filter cart. Your M400‑V will thank you, and so will your wallet.
