These Komatsu D85EX-15E0, D85PX-15E0 crawler dozers are mid-size earthmovers used for bulk pushing, slope work, and site prep. The Shop Manual SEN00060-18 is what working techs and serious owner-operators reach for when the machine isn’t just “due for service” but actually needs troubleshooting or repair. People buy this when they’re ready to go deeper than the Operation & Maintenance book and want the “how and why” behind teardown and diagnostics.
What this manual helps you do
- Trace electrical and electronic faults on the D85EX-15E0 and D85PX-15E0 using wiring diagrams and step-by-step test procedures.
- Diagnose engine, powertrain, steering, and braking issues with guided checks instead of random parts swapping.
- Follow disassembly and reassembly sequences for major components so you don’t miss hidden fasteners or damage seals on the way out.
- Check and adjust linkages, undercarriage components, and hydraulic controls to correct common performance complaints students often misdiagnose.
- Verify post-repair settings and machine functions so you can confidently return the dozer to service and document what was done.
Who this is for
This shop manual is aimed at field technicians, dealership and independent shop mechanics, and advanced trainees learning full machine repair. If you’re just running the dozer and want operating tips and daily service points, you’d be better off with the Operation & Maintenance Manual instead.
FAQ
Q: Is this a PDF I can search and print?
A: Yes, this is a digital PDF you can search by keyword and print pages or sections you need in the shop.
Q: Does it go deep enough for full overhauls?
A: Yes, the Komatsu D85EX-15E0, D85PX-15E0 Crawler Dozer Shop Manual walks through diagnostic procedures, disassembly sequences, and workshop checks used during major repairs.
Q: How do I know it matches my exact machine?
A: This manual is identified as SEN00060-18; you should match that to the literature number recommended for your specific serial number through your Komatsu dealer.
Bottom line: if you’re repairing or teaching repair on these exact D85EX-15E0 or D85PX-15E0 dozers, this is the right manual; if you only need basic operation and routine service info, keep looking for the O&M book instead.
