What is the operating weight of the Komatsu AFE47-BX(730E S/N A30243 - A30245 BUFFALO COAL)?
The operating weight varies by configuration/series.
What replaced the Komatsu AFE47-BX(730E S/N A30243 - A30245 BUFFALO COAL)?
The Komatsu AFE47-BX(730E S/N A30243 - A30245 BUFFALO COAL) was replaced by the Komatsu 730E-10.
What AFE47-BX(730E S/N A30243 - A30245 BUFFALO COAL) owners discuss
What engine powers the Komatsu AFE47-BX(730E S/N A30243 - A30245 BUFFALO COAL) trucks?
The machine is equipped with a Komatsu SSDA16V159E-2 engine, delivering 1492 kW (2,000 HP) of output. The powertrain utilizes an advanced fuel system designed to reduce noise and vibration levels in the equipment. The engine is part of the 730E series configuration for this specific serial range (A30243 - A30245). Engine specifications can vary by configuration/series across the broader 730E line; verify the exact engine code on the machine's data plate.
What are the known powertrain and hydraulic behaviors for this machine type?
Operators report that hydraulic system performance is closely tied to engine RPM under load. If the engine drops heavily in RPM when hydraulics are used, the hydraulic system may be placing excessive load on the engine or the engine may be unable to produce its expected power. If engine speed remains normal but hydraulic movements become weak, the hydraulic system moves higher on the suspect list. Shared hydraulic supply, pump control, engine performance, or pressure regulation deserves attention first if every hydraulic function is weak. Do not diagnose the pump simply because the machine is weak when hot; measure system performance cold and hot. Pressure and flow information is stronger evidence than temperature behavior alone.
What undercarriage or wear patterns are typical for this machine type?
Undercarriage wear is influenced by track tension and material type. A machine that drifts or pulls while travelling should not immediately be diagnosed as having a failed travel motor. Check mechanical conditions first: track tension on both sides, mud or debris packed into one undercarriage, roller condition, and track-chain condition. If mechanical resistance is similar but one track consistently runs slower, hydraulic or final-drive diagnosis becomes more relevant. Test the symptom in both forward and reverse. If the same side remains weak in both directions, that is more useful information than a single forward travel test. Track tension and undercarriage wear require regular inspection to prevent repeated loosening.
What are the common electrical/sensor issues for this series?
Multiple fault codes often point to battery, grounds, or connectors. A battery can show acceptable voltage until the starter is loaded. If the display dims heavily or voltage collapses during starting, perform a proper load and voltage-drop test before ordering a starter. Check battery state of charge, battery terminals, engine and chassis grounds, main starter cable, starter relay and control circuit, and applicable safety or neutral-start inputs. The advanced monitoring system facilitates the operator to identify parts that require maintenance, reduces diagnostic time, provides an indication of when to change the oil filter, and provides fault code information to maximize engine productivity. All Komatsu machines for mining and quarrying are equipped with KOMTRAX Plus (satellite-based communication system) as a complete service and program support.
What should be checked when buying a used AFE47-BX(730E S/N A30243 - A30245 BUFFALO COAL)?
Verify the exact serial-prefix specification sheet and installed attachment package. A long stick, wide track shoe, quick coupler, auxiliary hydraulics, or regional emissions configuration can change weight, reach, fuel use, and transport planning. Before buying, renting, or estimating ownership cost, confirm the exact serial-prefix specification sheet and installed attachment package. Data Accuracy Note: Equipment specifications, operating weights, and fuel consumption figures are sourced from manufacturer technical data sheets and field testing. Always consult official OEM service manuals for precise operating specs and safety protocols.
How does the cooling system typically behave under heavy excavation loads?
An excavator cooling package operates in an environment full of dust, dirt, and fine debris. Inspect first: radiator, hydraulic oil cooler, charge-air cooler where fitted, air-conditioning condenser, spaces between stacked coolers, coolant level when cold, and fan operation. A machine may look clean from the outside while material is packed between heat exchangers. Useful operating pattern: If temperature rises during heavy work but falls when the excavator is allowed to idle, cooling capacity may be marginal rather than completely absent. If coolant is repeatedly expelled or the system becomes highly pressurized shortly after a cold start, deeper engine diagnosis may be required.
What safety-critical fixes are associated with the brake cabinet assembly?
The brake cabinet assembly is a critical safety component. Have your dealer verify the brake cabinet assembly integrity and function.
