Komatsu D65EX-15, D65PX-15 Bulldozer Operation and Maintenance Manual (EEAM023203)
These D65EX-15 and D65PX-15 dozers spend their lives pushing dirt on construction pads, roadwork, and in harsher jobs like quarry and landfill work. This operation and maintenance manual is what I use to set a sane service rhythm, so the machine stays predictable under load and doesn’t surprise you with downtime. If, for example, the operator reports sluggish blade response and odd noises after a long push, I’ll go to this book to verify basic checks, schedule the right inspections, and rule out simple maintenance misses before tearing into components.
Applications & Use Cases
- Plan preventive maintenance so filters, fluids, and inspections are done on time and in a logical sequence.
- Walk operators through daily checks to catch leaks, loose hardware, or track issues before they turn into failures.
- Trace early wear signs on undercarriage and blade gear by comparing real-world conditions to the manual’s recommendations.
- Align service intervals with your job schedule to minimize lost production during peak work.
- Train new operators on proper warm-up, shutdown, and operating habits that extend component life.
FAQ
Q: Can I keep this manual on a tablet in the cab?
A: Yes, it’s practical to use digitally; you can zoom diagrams and search terms quickly during checks.
Q: Is it worth printing certain pages?
A: I’d print the inspection and service-interval charts to hang in the workshop or job trailer for quick reference.
Safety Note
Always follow the manual’s safety procedures and lockout steps before inspecting, adjusting, or servicing the dozer.
