Servicing the GD705A-4-R(S/N 21001-UP) beyond the schedule
Predictive Maintenance & Fluid Analysis
Utilize Komatsu KOWA fluid analysis at every 500-hour interval to monitor engine wear metals and hydraulic contamination levels. Check the coolant SCA concentration at 500 hours to prevent liner cavitation in the S6D125-1 engine. Monitor the air filter restriction indicator daily; replace the outer element at 1,000 hours or when indicated. Inspect the hydraulic return filter strainer at 500 hours to maintain pump integrity. Track fuel consumption trends to detect injector issues early. Use KOMTRAX telematics to correlate load frequency with fluid degradation rates for optimized service timing.
Corrective & Common Repairs
Address frequent leaks at the circle gear case seals and final drive output shafts. Replace worn circle gear pins and bushings to prevent moldboard alignment issues. Inspect the tandem drive case for oil contamination, which indicates front wheel bearing failure. Check the turbocharger rotor play and tighten all mounting bolts at 1,000 hours. Replace worn cutting edges and end bits to maintain grading efficiency. Inspect the brake system pads and discs regularly, as heavy grading duties accelerate wear on the wet disc brakes.
Overhaul & Rebuild Points
Plan for major powertrain overhauls around 10,000 to 15,000 hours, depending on duty cycles. Rebuild the S6D125-1 engine when compression drops below specification or oil consumption exceeds limits. Inspect the tandem drive case gears and bearings at 20,000 hours; replace if pitting or noise is detected. Check the circle reverse gear case for gear wear and backlash. Evaluate the hydraulic pump and motor case pressures for efficiency loss. Inspect the frame and moldboard welds for stress cracks, particularly around the circle mounting points.
Seasonal & Environment Servicing
In cold weather, use low-viscosity engine oil and ensure the coolant mixture provides adequate freeze protection. Drain the fuel separator daily to prevent water freezing in the lines. In dusty environments, clean the radiator and oil cooler fins frequently to prevent overheating. Check the air filter inner element more often in high-dust conditions. In hot climates, monitor hydraulic oil temperature and ensure the fan belt tension is correct. Store the machine with the blade lowered to the ground to relieve hydraulic pressure and prevent seal degradation during long-term storage.

What model replaced the GD705A-4?
The GD705A-4 was succeeded by the GD705-5 series, which introduced updated emissions compliance, refined undercarriage durability, and improved operator comfort features.
What GD705A-4-R(S/N 21001-UP) owners discuss
What engine powers the Komatsu GD705A-4-R (S/N 21001-UP)?
The Komatsu GD705A-4-R (S/N 21001-UP) is powered by the Komatsu SA6D140E-2 engine. This is a six-cylinder, water-cooled, turbocharged, aftercooled diesel engine designed to meet Tier 4 Final / EU Stage V emissions standards. The engine features an electronic control module (ECM) for precise fuel injection and monitoring. Note: Earlier GD705A-3 models used the SA6D140E-1, but the -4 series introduced the E-2 variant for improved efficiency and emissions compliance. Always verify the specific engine code on the engine data plate, as regional emissions packages can vary by configuration/series.
What are the common hydraulic system behaviors and failure modes for this motor grader?
Operators report that the GD705A-4-R hydraulic system is generally robust but sensitive to oil contamination and temperature. A common issue is sluggish blade control when the hydraulic oil is cold, which typically resolves as the oil warms up. If functions remain slow when hot, internal leakage in the main control valve or hydraulic pumps is likely. Cavitation noise from the hydraulic pump often indicates a clogged suction strainer or low oil level. Regularly check the hydraulic oil condition and replace filters at recommended intervals to prevent premature wear of the pilot control valves and main pump components.
What undercarriage and wear patterns are typical for the GD705A-4-R?
The GD705A-4-R uses a rigid frame with a front axle and rear tandem axle configuration, not a tracked undercarriage. Wear patterns typically focus on the front axle kingpins, steering cylinders, and tire condition. Operators note that excessive tire wear often results from improper tire pressure or misaligned front axles. The blade cutting edges, moldboard, and side cutters wear quickly in abrasive conditions and require frequent inspection. Check the front axle pivot pins for play, as wear here can cause unstable grading and uneven tire wear. Grease all steering and blade cylinder pins daily to prevent premature seal failure.
What are the known engine quirks for the GD705A-4-R series?
The SA6D140E-2 engine in the GD705A-4-R is known for its durability but can exhibit power loss if the air intake system is restricted. Common quirks include difficulty starting in cold weather if the glow plug system or battery is weak. The engine may derate if the aftertreatment system (if equipped with DPF/DOC) becomes clogged or if the DEF quality is poor. Monitor the exhaust backpressure sensor and DEF tank level regularly. Ensure the fuel filters are changed frequently to prevent injector wear, as Komatsu engines are sensitive to fuel cleanliness. Always check for air leaks in the intake manifold after turbocharger service.
What are the common electrical and sensor issues for this machine?
Electrical issues in the GD705A-4-R often stem from corroded connectors or loose grounds, particularly in the main harness near the engine and transmission. Operators report intermittent dashboard warnings or failure to start due to faulty battery disconnect switches or corroded battery terminals. The ECM can throw false codes if sensor wiring is chafed against the frame. Check the alternator output and starter connections for corrosion. Ensure all ground straps between the engine, chassis, and cab are clean and tight. Use dielectric grease on connectors to prevent moisture ingress.
What should be checked when buying a used GD705A-4-R (S/N 21001-UP)?
When inspecting a used GD705A-4-R (S/N 21001-UP), verify the serial number matches the documentation. Check the engine for excessive blow-by and smoke under load. Test all hydraulic functions for speed and pressure, especially the blade lift and tilt circuits. Inspect the front axle kingpins for wear and play. Check the tires for uneven wear or damage. Verify the operation of all lights, gauges, and the ECM for stored fault codes. Inspect the blade for wear and check the condition of the cutting edges and moldboard. Ensure the transmission shifts smoothly in all gears and that there are no leaks from the hydraulic system or engine.
What safety-critical fixes require dealer verification?
Safety-critical systems such as the braking system, steering system, and rollover protective structure (ROPS) must be inspected and repaired by a qualified dealer or technician. Do not attempt to modify or bypass safety interlocks, such as the seat switch or parking brake interlock. Have your dealer verify the calibration of the hydraulic pressure relief valves and the alignment of the front axle. Ensure all safety labels are present and legible. Regularly inspect the condition of the ROPS and FOPS structures for cracks or damage. Have your dealer verify the integrity of the fuel system and exhaust aftertreatment components to ensure compliance with emissions regulations.
