These Komatsu D85EX-15, D85PX-15 crawler dozers are mid-size production machines used for bulk push, slot dozing, and finish grading on larger sites. People usually reach for the Shop Manual when a fault light won’t clear, a component needs to come off the machine, or they’re planning a rebuild during a scheduled downtime window. If you’re trying to keep machines turning dirt and avoid surprise bills from the dealer, this is the book you’re thinking of.
What this manual helps you do
- Trace hydraulic and drivetrain faults using the diagnostic procedures and troubleshooting charts you’d expect in a dealer-level shop manual.
- Check step‑by‑step disassembly and assembly sequences for major components like the powertrain, final drives, hydraulics, and undercarriage systems.
- Follow wiring and hydraulic schematics for the D85EX-15 and D85PX-15 to track down electrical issues, sensor problems, and control faults.
- Diagnose performance complaints (weak pushing power, slow blade functions, overheating) with guided test points and adjustment procedures.
- Verify repair work with inspection steps and adjustment guidelines so you can sign off a job and put the dozer back in the rotation with confidence.
Who this is for
This Komatsu D85EX-15, D85PX-15 Crawler Dozer Shop Manual (SEBM029117) is aimed at field techs, shop mechanics, and fleet managers who schedule and oversee repairs. It’s not an operator’s handbook; if you mainly need daily checks, basic maintenance, or safety info, you’re better off with the Operation & Maintenance Manual instead.
FAQ
Q: Is this a PDF I can search and print?
A: Yes, it’s a PDF, so you can search by keyword and print the pages you want to send with a tech or put in a job folder.
Q: Does it go deep enough for engine or transmission work?
A: This is a workshop-level shop manual, so it’s built for full tear-down and repair, not just basic maintenance.
Q: How do I know it matches my exact D85EX-15 or D85PX-15?
A: Check your machine identification plate against the model designation and book reference SEBM029117; if your dealer recognizes that book number for your machine, you’re covered.
Bottom line: if you’re planning to keep these dozers in-house for diagnostics and major repairs, you’ll get value from this; if you just want operating tips and intervals, keep looking for the O&M manual instead.
