This Caterpillar MD6640 Parts Manual is the full illustrated parts catalog for the MD6640 Blast Hole Drill in the DR612180 / 2Z70A45 serial range. Every assembly on the machine — from the A-frame and crawlers through the rotary head, pulldown gearcase, mast, pipe racks, hydraulic valve banks, air compressor, water injection system, operator cab, and electrical cabinets — is broken down into exploded diagrams with item callouts and corresponding part numbers. The catalog covers hydraulic manifolds and valve banks, hydraulic cylinders for the mast, jacks, pipe rack, and boarding stairs, the propel gear case and propel motors, the air end and compressor assembly, the separator assembly, the lube system, and the full electrical schematic set for the light plant, PLC nodes 1 through 5, and power distribution. A full part-number index and part-description index at the back let you search either direction: from a part number on a component, or from a description to its part number and location. This manual is a parts catalog, not a service or repair manual — it provides the illustrated parts breakdown, part numbers, quantities, and assembly structure; it does not include repair procedures, torque values, or step-by-step rebuild instructions.

Who This Caterpillar MD6640 Parts Manual Is For

This Caterpillar MD6640 Blast Hole Drill Parts Manual is written for the people who keep these drills running: maintenance planners ordering replacement parts, mechanics identifying what came off the machine and what goes back on, parts counter staff confirming the correct number before an order ships, and rebuild shops quoting a repair. Because every assembly is shown as an exploded view with numbered callouts tied to a parts list, you can positively identify a component — a hydraulic cylinder seal kit, a valve cartridge, a crawler link, a rotary gearcase bearing, a compressor cooler hose — even when the part itself is worn beyond recognition. Instead of guessing from a photo or a sketch on a notepad, you match the illustration to the assembly, read the item number, and order against the exact part number printed in the catalog. That alone eliminates the costly cycle of wrong-part orders, return shipping, and a machine sitting idle while the correct component is re-ordered. For a drill of this size, an incorrect part is not a small mistake — it is downtime on a production hole, and this catalog is what prevents it.

Why the Correct Part Number Matters on an MD6640

The MD6640 is built around multiple hydraulic circuits, a rotary head, a pulldown system, pipe handling equipment, and a compressor and water injection system that all share similar-looking components across different circuits. A flow control valve in one manifold bank may look identical to a valve in another bank but carry a different part number and a different pressure setting. A hydraulic cylinder on the mast hoist may share a seal kit with a jack cylinder, or it may not. The illustrated parts breakdown resolves those ambiguities by tying each part number to a specific assembly and a specific item on the diagram, so you order the part that belongs to the circuit you are actually repairing. The catalog also documents the kit numbers — cylinder seal kits, cartridge seal kits, valve seal kits, disc brake kits, injector repair kits, charge pump update kits, filtration kits, and overhaul seal kits — so a rebuild can be planned as a single kit purchase rather than a list of individual seals and O-rings.

How the Illustrated Parts Breakdown Is Organized

Assemblies appear in the catalog in the same order as the machine’s major groups: the A-frame and front legs, the main frame and rear jack casings, the crawlers and propel gear cases, the rotary gearcase and pulldown gearcase and shafts, the mast and mast guide rollers and mast hydraulic piping, the pipe racks and pipe handling equipment, the hydraulic valve banks and manifolds, the air compressor and air end and separator, the water injection system, the operator cab and its interior, the machinery house, and the electrical cabinets and schematics. Each assembly page carries a diagram with numbered balloons that correspond to a parts table listing item number, quantity, part number, and description, with a notes column where a part has a specific fitment, an alternate, or a customer-rep contact requirement. The part-number index and the part-description index at the back of the manual let you jump directly to the correct assembly page from either direction.
