Across every one of those sections, the parts tables follow the same consistent format: reference number, part number, quantity, unit of measure, and description. Where a sub-assembly is used, the table directs you to the figure that illustrates it, so you can move from the top-level assembly drawing down to the individual component level without guesswork. That figure-and-table pairing is what makes an illustrated parts list like this usable in a shop environment — you identify the part visually, then confirm the exact number and quantity before you order.

What This DM45 HP Parts Catalog Covers

Because this is a serial-number-specific parts book for DM45 HP serial 7981, the part numbers, quantities, and assembly configurations it lists are tied to that exact machine. Atlas Copco builds each parts book to a specific drill, and the header on every parts page carries both the drill serial number and the model description. This catalog matches the configuration of the rig carrying serial 7981 rather than a generic DM45 specification, which is precisely what you need when ordering replacement parts for a machine that may have been built with options or revisions not reflected in a different serial’s book.

The document covers the engine package (CAT C16 600HP), the compressor system (1070 HR2.5), the full hydraulic circuit from main pump through valve blocks and cylinders, the undercarriage and final drives, the tower and rotary head, and the cab and console. It also documents the Arctic variants of several assemblies, including the tower pinning, breakout, dust curtain, and piping groups, plus Russia-market decal and manual packages. Whether your rig is a standard DM45 HP or an Arctic-configured unit, the relevant exploded views and tables are present.

How to Use This Atlas Copco DM45 Parts List

Start with the chapter list to find the assembly you are working on. Open its figure page to identify the reference number for the part you need, then cross-reference that number in the accompanying parts table to get the exact part number and quantity. Each figure is keyed to its table, so the two always work as a pair. The alphabetical index at the back lists parts by part number, making it quick to confirm which assembly a given component belongs to — useful when you have a loose part number and need to know where it goes on the machine.

Why DM45 HP Owners and Technicians Use This Catalog

Ordering the wrong part for a drill rig is expensive in both money and downtime. This catalog removes the guesswork by showing the exact configuration for serial 7981 and providing the part numbers that Atlas Copco assigned to that build. Whether you are replacing a final drive component, tracing a hydraulic hose, matching a seal kit, or rebuilding a rotary head, the figures and tables give you the part number and quantity to order. The distributor serving your area can supply genuine replacement parts — and the more precisely you identify the part, the faster that service goes.

The range of systems covered is broad: the IRGT2500 final drive, the HR 2.5 air end, the CAT C16 engine installation, the 6-spool and 9-spool hydraulic valve assemblies, the rod changer and rod support groups, the dust collector, and the water injection option, to name a few. For anyone maintaining or repairing a DM45 HP, having the correct serial-specific parts book on hand is the difference between a quick parts order and a guessing game.
