These Komatsu D85EX-15R, D85PX-15R Crawler Dozers are mid-size earthmoving machines used for pushing, cutting, and grading on construction, mining, and landfill sites. The Shop Manual (SEN02947-13) is what a field tech, dealer shop, or heavy equipment mechanic reaches for when the dozer is down and you’ve got tools out, not just a grease gun. People usually want this manual when they’re doing real repairs, chasing warning lights, or rebuilding major components to cut downtime and avoid guesswork.
What this manual helps you do
- Trace hydraulic and electrical faults on D85EX-15R and D85PX-15R machines using step‑by‑step diagnostic flows and wiring information.
- Follow correct disassembly and reassembly sequences for major components like final drives, powertrain, and work equipment.
- Check wear points and adjustment procedures for undercarriage, blade controls, and steering/braking systems before parts ordering.
- Diagnose engine‑related issues on the dozer using the kind of tests and inspection steps most shops rely on.
- Handle calibration and setting procedures after component replacement so the machine goes back to work without repeat failures.
Who this is for
This is aimed at a field technician, shop mechanic, or fleet maintenance lead who actually turns wrenches on Komatsu D85EX-15R or D85PX-15R dozers. If you’re just operating the machine or only need daily/weekly service info, you’d be better off with the Operation & Maintenance manual instead.
FAQ
Q: Is this a searchable and printable file?
A: Yes, it’s a PDF you can search on a laptop or tablet and print specific sections for use in the field.
Q: Does it go deep enough for full overhauls?
A: The Komatsu D85EX-15R, D85PX-15R Crawler Dozer Shop Manual walks through diagnostic procedures, disassembly sequences, and workshop‑level repair steps that most rebuild jobs require.
Q: How do I know if it matches my serial number or variant?
A: This manual is tied to book number SEN02947-13; you should match that against your Komatsu literature or dealer to confirm it fits your exact machine build.
Bottom line: If you’re repairing or troubleshooting a D85EX-15R or D85PX-15R and need shop‑level guidance, this is the right manual; if you only want basic operation or service intervals, keep looking for the O&M book instead.
