Komatsu SAA6D114E-2A-A(S/N 26800003-UP)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu SAA6D114E-2A-A engine (S/N 26800003-UP) is a heavy-duty, inline 6-cylinder, 4-stroke diesel powerplant used in the PC300-7 and PC300LC-7 hydraulic excavator series. This mid-size machine class operates in the 20,000 to 60,000 lb weight range and was produced during the late 2000s to early 2010s. The SAA6D114E-2A-A succeeded the SA6D114E-1 series and was later replaced by the SAA6D114E-3 series in the PC300LC-8 generation. Configurations included standard and long-reach boom setups, with the engine delivering approximately 196 hp at 2050 rpm.
Across generations, the SAA6D114E-2A-A introduced a more robust turbocharging and aftercooling system compared to its predecessor, improving thermal efficiency and durability in severe construction environments. The machine remains highly relevant in the used and parts market due to the widespread availability of the 8.27L platform architecture, which shares core components with the Cummins QSC8.3. Its continued presence in the secondary market is driven by the extensive ecosystem of Komatsu CARE maintenance programs and the availability of high-quality remanufactured engine assemblies and overhaul kits.

Servicing the SAA6D114E-2A-A(S/N 26800003-UP) beyond the schedule
Predictive Maintenance & Fluid Analysis
Utilize the KOWA (Komatsu Oil Wear Analysis) program at every 500-hour interval to monitor engine oil, hydraulic fluid, and coolant health. Analyze samples for wear metals such as iron, copper, and lead, and identify contaminants like silicon (dirt) or sodium (coolant). Regular sampling detects fuel dilution, soot levels, and viscosity changes early. This data allows for proactive scheduling of oil changes and component replacements before catastrophic failure occurs, ensuring the SAA6D114E-2A-A powertrain remains within optimal operating parameters.
Corrective & Common Repairs
Address common SAA6D114E-2A-A failures by inspecting the turbocharger and fuel injectors during the 1,000-hour service. Check for coolant leaks around the head gasket and water pump seals, which are frequent failure points in this 8.27L platform. Inspect the air intake system for blockages that cause excessive soot accumulation. Replace worn belts and hoses during the 2,000-hour service to prevent sudden breakdowns. Monitor the EPC solenoid valves for electrical faults that may trigger output reduction codes.
Overhaul & Rebuild Points
Major overhaul milestones for the SAA6D114E-2A-A include the 2,000-hour hydraulic oil change and coolant flush. Critical rebuild focus areas involve the swing machinery, final drives, and engine components such as the turbocharger and injectors. Use out-of-frame overhaul kits for piston rings, bearings, and gaskets when compression drops or oil consumption increases. Verify crankshaft center and flywheel housing rear surface dimensions during major engine disassembly to ensure proper alignment and prevent premature wear.
Seasonal & Environment Servicing
In cold climates, ensure the Super-coolant AF-NAC concentration is adequate to prevent freezing and maintain proper SCA levels. Drain water from the fuel separator daily to prevent ice formation in the fuel lines. In dusty environments, check the air filter restriction indicator more frequently and clean the radiator and oil cooler fins to prevent overheating. Verify the integrity of the ROPS/FOPS structure and tighten all structural bolts during the 1,000-hour inspection to maintain cab safety and operator comfort.

SAA6D114E-2A-A(S/N 26800003-UP) attachments & work tools
Excavator Attachments
The SAA6D114E-2A-A engine (S/N 26800003-UP) powers the PC300-7 and PC300LC-7 excavator series. Typical work tools include standard digging buckets, trenching buckets, and heavy-duty rock buckets. Factory configurations for this class often include quick coupler systems and various tooth styles (e.g., wedge, bolt-on) to match ground conditions. Hydraulic flow requirements for auxiliary circuits (e.g., tilt rotators) depend on the specific machine's hydraulic kit configuration.
Wheel Loader Attachments
This engine is used in the WA380-5 and WA430-5 wheel loader models. Primary work tools include general-purpose buckets, light material buckets, and heavy-duty rock buckets. Mounting systems typically utilize a standard skid-steer style quick attach or a proprietary Komatsu quick coupler. Hydraulic kit arrangements must support the loader's lift arms and auxiliary circuits for grapples or forks if equipped.
Motor Grader Attachments
The SAA6D114E-2A-A engine is installed in the GD655-3 and GD675-3 motor graders. Standard work tools include the moldboard (blade) with straight or angle configurations, and various ripper configurations for the rear. Factory guarding options may include side cutters, wing extensions, and blade wear strips. Hydraulic arrangements control the moldboard lift, tilt, and angle functions.
Crawler Carrier Attachments
The CD110R-2 crawler carrier utilizes this engine for industrial applications. Work tools are specialized for material handling, such as grapples, clamshell buckets, or specialized forks. Mounting is typically via a fixed frame or a heavy-duty quick coupler system designed for high-load cycles. Hydraulic systems are configured for high-flow operations required by grapple or clamshell mechanisms.
Industrial/Power Generation Options
The engine is used in mobile crushers and stationary power units. For mobile crushers, work tools include crushing chambers and screen decks. For power generation, the configuration involves alternator mounting and control panels. Factory guarding options include sound attenuation enclosures and exhaust silencing systems to meet emission and noise regulations.
