Doosan DX27Z Parts Catalog – 316-Page OEM Parts Manual

If you are tracking down a part number for a Doosan DX27Z mini excavator and you don’t have the factory book, you are wasting time. I have seen mechanics order the wrong seal kit because they guessed. That costs money and downtime. This Doosan DX27Z Parts Catalog is 316 pages of OEM part numbers, exploded views, and ordering codes. No third-party interpretation. Just the factory data from Doosan. The foreword on page 5 lays out the ordering procedure step by step – machine serial number, engine serial number, part number, quantity. If you skip that, your parts counter guy will hand you the wrong piece. I’ve been there.

Filter and Service Interval Table

Page 3 of this catalog has the filter lineup with part numbers and replacement intervals. Engine oil filter is K1025334 at 250 hours. Fuel filter K1025335 at 500 hours. Air cleaner inner and outer elements: K1025337 and K1025338 at 500 hours. Suction filter oil tank K1011555 at 1000 hours, return filter K1011327 at 1000 hours, air breather element K1029257 at 1000 hours. Belt replacement interval for the fan belt DS3202026 is 1000L. That table alone saves you from cross-referencing aftermarket catalogs that might be wrong. Use the factory numbers.

Seal Kits and Undercarriage Components

Hydraulic leaks on a DX27Z usually come from cylinder seals or the swing motor. This catalog lists seal kits for boom (K9005267), arm (K9005266), bucket (K9005268), boom swing (K9005270), dozer (K9005269), track spring (2440-9266AKT), center joint (K9004888), swing motor (K9005209), and travel motor (K9005300). Undercarriage parts: idler K1014352A, upper and lower rollers, track springs left and right, sprocket K1014434, rubber tracks in 250mm or 300mm widths. Those track part numbers are K1014357 and K1025569. Ordering the wrong track width means a return. Check your machine.

3 Systems Covered by the 316-Page Catalog

The catalog breaks down the machine into logical groups. Engine and related components – gasket kit K9005228, filters, belts. Electrical system – battery 2506-9009, fuses (10A to 30A), relays 2544-9032, bulbs (12V 2W, 55W halogen, 10W). Hydraulic and undercarriage – pumps, motors, cylinders, seals. Each section has an exploded illustration with key numbers that match the parts list. That’s how you avoid ordering a part that looks right but doesn’t fit. The OEM drawings are dimensionally accurate, unlike aftermarket sketches.

How to Use the Parts List: What the Foreword Tells You

Page 5 has the instructions. When you order, you need: model (DX27Z), machine serial number (on the bed frame nameplate, e.g. HEACO-0000), engine serial number (on cylinder block, 3TNV82A-SDB), part number, description, qty. The catalog uses key numbers on illustrations. Assembly parts are marked with [•], sub-components with [••]. Service codes in the last column tell you if a part is optional or a running change. Do not ignore the service code column. I have seen a tech order a part that was superseded because he didn’t check the code. This catalog gives you that info.

Bulbs, Fuses, and Electrical Parts

Electrical failures on a mini excavator often come from blown fuses or bad bulbs. The catalog lists the exact part numbers: bulb 12V 2W (515-00001A), halogen 12V 55W (2515-1016D2), 12V 10W (2515-1021D6). Fuses: 10A (2527-1016), 15A (2527-1017), 20A (2527-1018), 30A (2527-1025). Relay 2544-9032. These match the factory harness. Aftermarket equivalents may have different terminal shapes or amp ratings. Use the OEM part to avoid a fire or a no-start. The battery is 2506-9009 – check your machine for CCA ratings.

Frequently Asked Questions

Does this parts catalog include engine rebuild specs?

No. This lists part numbers only, not repair steps.

What is the difference between a parts catalog and a service manual?

A parts catalog shows exploded views and part numbers for ordering. A service manual contains repair procedures, torque specs, and diagnostics. You need both for full coverage.

Can I use this to order parts directly from Doosan?

Yes. The foreword on page 5 specifies the ordering procedure: provide model (DX27Z), machine serial number (e.g., HEACO-0000), engine serial number (3TNV82A-SDB), part number, description, and quantity. This manual is the official Doosan reference for ordering genuine parts. Without these details, your order may be delayed or incorrect. Each part number is verified by the factory.

How many pages is this catalog and does it cover all DX27Z variants?

316 pages. It covers the standard DX27Z mini excavator. Variations like special undercarriage options (250mm or 300mm rubber tracks) are included from page 3.

If you need to keep your DX27Z running without ordering the wrong part again, access the Factory Manual. It will save you a return trip to the parts store.
