Komatsu D37EXi-24, D37PXi-24, D39EXi-24, D39PXi-24 Bulldozer Operation and Maintenance Manual (TEN00766-02)
These D37/D39 i-series dozers usually live on construction pads, road jobs, and tight grading sites where the machine is always pushing, fine-leveling, and working around other equipment. This Operation and Maintenance Manual helps you set a steady service rhythm so the dozer is ready every morning and the intelligent control stays reliable. When, for example, the machine starts grading unevenly or the auto blade feels “lazy,” this is what you’d use to verify basic settings, walk through the daily checks, and rule out simple maintenance misses before calling in deeper diagnostics.
Applications & Use Cases
- Plan preventive maintenance so filters, undercarriage, and cooling system are inspected and serviced before they cause downtime.
- Trace early wear in tracks, rollers, and blade linkages using the recommended inspection points and patterns.
- Verify operator checks at shift start—fluids, warning lights, machine walk-around—so issues are caught in the yard, not in the cut.
- Support intelligent control reliability by keeping sensors, harness routing, and electrical connections in healthy condition.
- Coordinate shop and field work, deciding what can be handled on-site versus what should be scheduled in the workshop.
FAQ
Q: Can I keep this manual on a tablet in the cab?
A: Yes, it’s well-suited for digital use; you can zoom diagrams and use search to jump straight to the procedure you need.
Q: Is it worth printing sections of this manual?
A: Many mechanics print the routine service pages and keep them in a binder or toolbox so they can mark dates, hours, and notes right at the machine.
Safety Note
Always follow the manual’s safety instructions and lockout procedures before inspecting, adjusting, or servicing the dozer.
