What This Parts Catalog Does for You

This is not a generic overview or a summarized parts list. It is the full, machine-specific parts catalog for the D61EX-15E0-BW, serial number B45001 and up. Every illustration is tied to an itemized table listing the exact part number, description, quantity required, and serial number applicability where relevant. That means when you look at an exploded view of the final drive, the hydraulic pump, or the operator’s cab, you can trace each numbered callout directly to the part number you need to order.

The catalog covers both standard and optional configurations. You will find dedicated sections for machines equipped with the poor fuel arrangement, the EU noise reduction arrangement, and various rear attachment setups. The serial number breaks are clearly marked, so you can confirm whether a part applies to your specific machine before placing an order. This level of detail saves time, avoids wrong-part purchases, and gives you confidence that the component you receive will fit and function correctly.

For anyone maintaining, repairing, or restoring a D61EX-15E0-BW, having the correct parts catalog is as important as having the service manual. The service manual tells you how to remove and install a component; the parts catalog tells you exactly which part to remove and install, and what else you might need while you are in there — seals, O-rings, shims, bolts, and other small items that are easy to overlook until reassembly.

How the Catalog Is Organized

The catalog follows Komatsu’s standard parts book layout. Each major system begins with an exploded-view illustration showing every component in its assembled position. Numbered callouts on the illustration correspond to a table on the same or facing page. The table lists the item number, part number, description, quantity, and any serial number or option restrictions.

Sub-assemblies are broken down further. For example, the alternator section includes both the complete alternator assembly and a separate inner-parts breakdown showing the rotor, stator, bearings, rectifier, regulator, and other internal components. The same approach applies to the starting motor, hydraulic pumps, control valves, and cylinders. This means you can order at whatever level you need — a complete assembly, a sub-assembly, or an individual internal part.

Coverage for Variants and Optional Equipment

The D61EX-15E0-BW was produced in several configurations, and this catalog accounts for them. You will find specific sections for the poor fuel arrangement (marked with serial number break B45994-), the EU noise reduction arrangement 2, and various rear attachment options. There are also sections covering the KOMTRAX wiring and antenna for machines equipped with that system.

For the operator’s compartment, the catalog covers multiple seat types — reclining, turn and reclining, air suspension, fabric and leather, with and without headrest — as well as cab and canopy configurations. The undercarriage section covers standard, long track, and plus type (serial number B46042-) track components, with separate part numbers for each.

Why This Catalog Matters for Your D61EX-15E0-BW

The D61EX-15E0-BW is a serious piece of earthmoving equipment. When something breaks or wears out, you need the right part the first time. Ordering a seal that is close but not exact, or a bolt with the wrong thread pitch, can lead to leaks, failures, and downtime that costs far more than the part itself. This catalog eliminates that risk by giving you the precise Komatsu part number for every component on the machine.

It also helps you plan ahead. By reviewing the exploded views, you can see which related parts should be replaced together — for example, when replacing a hydraulic cylinder rod, you can quickly identify the corresponding seal kit, bushing, and wear ring. When servicing the final drive, you can see the shim sizes and bearing part numbers you may need to adjust preload. That kind of foresight keeps repairs moving and reduces the chance of a second teardown because a small part was missed.
