Atlas Copco DM45, HP Parts Catalog

I’ve been wrenching on heavy equipment long enough to know that ordering the wrong part costs you a full shift and then some. This Atlas Copco DM45, HP Parts Catalog is the factory-issued document that tells you exactly which bolt, hose, or seal goes where. 830 pages of part numbers, exploded views, and callouts for the DM45 and HP models. No guesswork, no aftermarket abbreviations that don’t match what’s stamped on your machine. If you’re maintaining a drill rig with serial US008705, this is the parts book you need on the bench.

830 Pages of Factory Part Numbers

Every parts catalog I’ve seen from a third-party printer leaves out half the hard-to-find items. This one doesn’t. It’s a direct scan of the OEM binder, covering every section from Frame/Chassis to Tools/Accessories. The page count alone – 830 pages – tells you nothing has been skipped. You get the exact same part numbers that Atlas Copco drilling solutions uses in their own warehouse. Need a fuel system component? The Fuel System chapter lists every line, fitting, filter, and pump with its original number. I’ve used this manual to track down a mis-documented hydraulic hose that three dealers couldn’t ID. It’s that specific.

What Systems Does the DM45/HP Parts Catalog Cover?

Open the table of contents and you see fourteen major sections: Frame/Chassis, Undercarriage/Tracks, Jacks, Cab/Console, Derrick/Tower, Powerpack/Engine, Air Cleaners, Fuel System, Compressor/Air System, Hydraulic System, Electrical System, Options, Tools/Accessories, and then a massive index of individual parts (A through Y). Each section breaks down into sub-assemblies with reference numbers. For example, the Powerpack/Engine chapter shows the mounting brackets, cooling lines, and the engine itself as a complete unit. The Electrical System chapter covers the wiring harness, switches, and control modules. If you’ve ever tried to match a sensor connector by eyeball, you’ll appreciate having the OEM diagram right there.

Powerpack/Engine Section: Finding the Right Component

Let’s say you’re rebuilding the engine deck on a DM45. The Powerpack/Engine section lists every component by part number and shows the assembly in an exploded view. You see the main frame part number 57761074 on page 2, then the rear platform deck 57711186 later in the section. The catalog gives you the quantity required per assembly – no guessing how many bolts go into the flywheel housing. I’ve watched a young tech order one seal instead of the three listed in the OEM manual because he used a generic cross-reference. That mistake cost him an afternoon of rework. This manual keeps that from happening.

Verify Your Serial Number Before Ordering

Atlas Copco warns you on page 3: “Be sure the parts book which you are ordering parts from is the parts book for the Drill needing the replacement parts.” This book is specific to serial number US008705. The serial number is welded on the frame at the drilling end. I’ve seen shops buy a generic DM45 parts list and end up with wrong undercarriage parts because later production runs changed the track tensioner design. You avoid that by matching the serial number on the header of each page. The manual includes a warning about California Proposition 65 for diesel engine exhaust – that’s a legal requirement, but it also confirms the manual is a genuine factory print. No reprints, no copied pages.

Why OEM Documentation Beats Aftermarket Copies

Third-party parts catalogs for drill rigs often omit the “Jacks” section or collapse multiple frame variants into one blurry diagram. This OEM catalog includes separate pages for the Jacks system, the Cab/Console interior, and even the Options group. Every line item has an index letter (A through Y) that keys back to the master parts list. You get the same documentation that the Atlas Copco dealer uses. If you’re ordering a fuel line for the Fuel System, you’ll see the thread specification in the note column – something aftermarket manuals never show. I’ve built my reputation on using factory data, and this catalog is the real deal.

Can I use this parts catalog for other DM45 models?

This catalog is serial-number specific to US008705. Using it for a different serial could result in wrong parts.

How do I identify the correct part number from the diagram?

Each page lists the part number next to the callout. You need to match the illustration index. For example, in the Powerpack/Engine section, the engine assembly has a reference number that corresponds to the part list. Always cross-check with the unit serial number. I’ve seen guys order a fuel filter based on a generic cross-reference and end up with the wrong thread pitch. The manual gives you the exact Atlas Copco part number. Don’t rely on aftermarket catalogs for drill rigs. The Electrical System section does the same for sensors and harnesses. No shortcuts.

If you’re working on a DM45 or HP drill rig and you need the exact part numbers that match your machine’s serial plate, stop relying on internet forums. Access the Factory Manual and keep it on your tablet or printed on the tool box. 830 pages of OEM data, no missing sections, no aftermarket reinterpretation. This is what the factory uses.
