John Deere 850K Crawler Dozer Operation and Test Technical Manual (TM12043)
You’ve got an 850K on a job, operator says “no power, pulls like a dead dog,” and the dash is clean. No codes, just lazy hydraulics and weak travel. Without TM12043 you’re guessing—swapping pumps, blaming turbos, burning hours. With it, you go straight to the right test ports, the right pressures, the right ECU checks. You stop guessing and start proving what’s actually failing.
Key Tasks Covered:
- Verify charge and main hydraulic pressures with the correct ports and spec ranges.
- Run powertrain stall tests and compare to rated torque values.
- Check HST pump and motor control signals from the ECU with pin-by-pin volt/ohm specs.
- Diagnose derate conditions using actual fuel rail pressure and boost targets, not “seat-of-pants.”
- Confirm pilot pressure to blade and ripper circuits before condemning valves or pumps.
Common Questions:
Q: “Machine’s gutless but no codes. Where do I even start?”
A: Follow the powertrain performance test: stall test, record RPM, compare to spec, then check HST control pressures and engine load data. It tells you if it’s engine, hydrostat, or load sensing.
Q: “Hydraulics are slow, pump or valve?”
A: Run the pump flow/pressure test first; if pressure hits spec but functions are slow, the manual walks you to spool leakage and pilot control checks.
Safety Note: Put the blade down, chock it, and bleed system pressure before you crack any line—850K hydraulics will hurt you fast.
