This parts list covers the DMH drilling rig from the ground up — the 375 undercarriage and final drives, the 65-foot tower and powerhead, the rod changer and breakout wrench, the CAT 3508 engine installation, the 350MM compressor and air system, the main hydraulic drive and all valve banks, the water injection option, dust curtains, central lube system, automatic leveling, PLC controls, and every hose, fitting, seal kit, and wear part in between. Each section gives you the Atlas Copco part number, the quantity required, and the description exactly as it appears in the factory parts book.

Why This Parts Manual Matters for Your DMH

Ordering the wrong part for a rig like this is expensive and slow. Atlas Copco built each DMH to a specific configuration, and this parts list was created for Serial Number 4260 — the DMH/XL2600/CAT3508/375 build. The header on every parts page confirms the serial number and model description, so you can match the book to your machine before you order a single component.

Whether you are replacing a final drive seal, tracking down a hydraulic hose for the main pump circuit, rebuilding a jack cylinder, sourcing a powerhead bearing, or finding the correct O-ring for a valve subassembly, this manual gives you the exact part number to hand to your dealer. The exploded illustrations show how components go together, which is invaluable when you are disassembling a rod catcher, a breakout wrench, a carousel, or the tower locking mechanism.
