These Komatsu D61EX-24, D61EX-24E0, D61PX-24 crawler dozers are mid-size production machines used for grading, pushing, and site prep on construction and earthmoving jobs. The people who usually reach for a Shop Manual are dealership techs, independent mechanics, and fleet shops trying to do real repairs, not just daily checks. They’re usually chasing a fault code, planning a teardown, or double-checking an adjustment before they button a machine back up.
What this manual helps you do
- Trace hydraulic and electrical faults on the D61EX-24 series using the system layouts and step-by-step diagnostic flows these manuals usually provide.
- Check disassembly and assembly sequences for major components like the diesel engine, powertrain, final drives, and undercarriage so you don’t miss hidden fasteners or seals.
- Follow adjustment procedures for items like linkages, brakes, steering, and blade controls, with the “why” behind the steps usually explained in notes and cautions.
- Diagnose electronic control issues by following typical Komatsu troubleshooting trees for sensors, controllers, and wiring on these specific dozer variants.
- Handle scheduled workshop-level service tasks correctly, including inspections that most students forget, like rechecking movement after adjustment or re-bleeding circuits.
Who this is for
This Shop Manual is aimed at field techs, shop mechanics, and serious trainees who are actually turning wrenches on these exact Komatsu D61EX-24, D61EX-24E0, and D61PX-24 crawler dozers. If you’re just operating the machine or only need service intervals and basic greasing points, you’d want the Operation & Maintenance manual instead.
FAQ
Q: Is this a PDF I can search and print?
A: Yes, it’s typically provided as a searchable PDF that you can view on a laptop or tablet and print specific pages for the job.
Q: Is it deep enough for full rebuilds, or just basic service?
A: This kind of Komatsu Shop Manual usually covers workshop-level repair, from diagnostics through major component disassembly, inspection, and reassembly.
Q: How do I know it matches my exact machine?
A: Check your dozer’s model designation and the book number SEN06855-12; if your plate shows D61EX-24, D61EX-24E0, or D61PX-24 and your serial range matches what your dealer confirms for this book, you’re in the right place.
Bottom line: If you’re repairing or training on these specific D61EX-24 series dozers in a shop or field setting, this is the manual you want; if you just need basic operation guidance, keep looking for the O&M book instead.
