IMAGES PREVIEW

This Komatsu D155A-6 Parts Book isn’t just a list of numbers. It’s the tool that lets a parts counter identify the exact component for the machine sitting in front of them. The exploded-view diagrams show how components fit together, which helps when a part is missing or when a previous repair left something incorrectly assembled. Every parts table includes the part number, description, quantity, and serial number range where that part applies. For a dozer that’s been in service for years, having those serial number breakouts is critical. Komatsu updated components across production runs, and this parts book tells you which version fits which machine.

How to Use This Parts Book

The SAA6D140E-5GR-W engine parts catalog section starts with the cylinder head and works through the entire engine assembly. Each illustration has numbered callouts that match the parts table directly below or beside it. The same structure repeats for every major system. If you need a specific bolt for the turbocharger mounting, locate the turbocharger mounting illustration, find the callout number, and the table gives you the part number and quantity. The serial number column tells you whether that bolt applies to your engine serial number or if there’s a different part for earlier or later units.

For the undercarriage, the track shoe section is particularly detailed. Different track widths and types are covered, from 560mm standard to 710mm wide, with lubricate and dry types, heavy-type versions, and special specs like cold weather and slag handling. Each track shoe assembly listing includes links, bushings, pins, seals, spacers, bolts, and nuts. The track frame sections break down the front idler, recoil spring, track rollers, carrier rollers, and rear cover for both left-hand and right-hand sides.

Work equipment coverage is extensive. Whether the machine has a straight tilt dozer, semi-U dozer, sigmadozer, full-U dozer, or coal dozer, the blade assembly, cutting edges, end bits, and mounting hardware are all documented. The ripper section covers multi ripper and giant ripper configurations, including shanks, points, protectors, and the pin puller cylinder. Dozer frame and trunnion parts are listed for tilt dozer and coal dozer applications.

What a Complete Parts Book Gives You

Ordering the wrong part is expensive and frustrating. This Komatsu D155A-6 bulldozer parts manual PDF eliminates that guesswork. With 834 pages of parts data and diagrams, it covers:

• Engine components from cylinder head to oil pan, including turbocharger, fuel system, cooling system, and electrical components
• Power train and final drive assemblies, including torque converter, transmission, steering, and final drives
• Hydraulic system lines and components for blade lift, blade tilt, ripper, and fan drive
• Main frame, suspension, and pivot shaft components
• Operator’s compartment, cab, seating, and control system parts
• Guards, hoods, fenders, and covers
• Complete undercarriage including track shoes, track frames, rollers, idlers, and recoil springs
• Work equipment blades, cutting edges, rippers, and cylinders
• Marks, plates, and decals in multiple languages
• Service kits and component parts for major assemblies

Because this is a dedicated D155A-6 parts catalog rather than a generic reference, every part is specific to this machine. The serial number ranges (D155A-6: 35001-35076; SAA6D140E-5GR-W: 630001-UP) ensure you’re looking at the right parts for the right production period. Whether you’re running a repair shop, managing a fleet, or maintaining your own D155A-6, having this parts book on hand means faster parts sourcing and fewer ordering errors.
