Komatsu PC95R-2(S/N 21D5200330-Up)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu PC95R-2 is a mid-size crawler excavator produced from 1999 to 2006. It is powered by a Komatsu 4D106-1FB engine delivering 82 HP (61 kW) net power. The machine has an operating weight of 19,291 lbs (8,750 kg) and features a tail swing radius of 60.0 in. (152.4 cm). Configurations include standard and long stick options, with bucket capacities ranging from 0.3 to 0.6 cu yds (0.2 to 0.5 m³). It succeeded the PC95-1 series and was later replaced by the PC95MR-2.
Across its generation, the PC95R-2 introduced improved hydraulic efficiency and a more compact tail swing design compared to its predecessor. It remains relevant in the used market due to its durable 4D106-1FB engine and widely available undercarriage parts. The machine is often sought for utility work and landscaping where its 87.6 in. (222.5 cm) width allows access to confined spaces.

Servicing the PC95R-2(S/N 21D5200330-Up) beyond the schedule
Predictive Maintenance & Fluid Analysis
Utilize KOWA oil analysis at every 500-hour interval to monitor engine wear metals and hydraulic fluid contamination. Check the coolant SCA concentration at 500 hours to prevent liner cavitation in the 4D106-1FB engine. Monitor hydraulic oil particle counts to detect pump or valve wear early. Track fuel dilution levels in the engine oil to identify piston ring or injector issues before they cause catastrophic failure. Use KOMTRAX telematics to correlate fluid health with load frequency and operating hours.
Corrective & Common Repairs
Address hydraulic hose leaks at connection points on the boom and stick, which are common failure sites on the PC95R-2. Replace worn track shoes and side cutters to maintain traction and reduce undercarriage stress. Inspect the 4D106-1FB engine injectors for clogging if power drops below 82 HP (61 kW). Check the swing bearing for play or unusual noise, indicating gear wear. Replace the hydraulic return filter if flow restriction causes overheating during continuous digging cycles.
Overhaul & Rebuild Points
Plan for major component overhaul at 10,000 to 15,000 hours. Rebuild the main hydraulic pump if flow drops below 47.6 GPM (178 LPM) or pressure relief settings fail. Inspect the final drive gears and seals for oil leakage and metal debris. Overhaul the 4D106-1FB engine if compression drops or blue smoke indicates excessive oil consumption. Check the swing motor gears for pitting or wear that affects the 10.2 RPM swing speed. Replace all track rollers and idlers if wear exceeds manufacturer limits.
Seasonal & Environment Servicing
In cold weather, use low-temperature hydraulic oil to ensure proper flow and prevent hose cracking. Drain the fuel water separator daily to prevent ice formation in the lines. Check the battery charge regularly as cold temperatures reduce capacity. In dusty environments, clean the radiator and oil cooler fins frequently to prevent overheating. Inspect the air filter restriction indicator more often and replace the outer element as needed. Ensure the DEF system is protected from freezing in sub-zero temperatures.

PC95R-2(S/N 21D5200330-Up) attachments & work tools
Buckets
Standard bucket capacity ranges from 0.2 to 0.5 cubic meters (0.3 to 0.6 cubic yards). Typical widths for this class are approximately 0.7 meters (27.6 inches). Variations exist between standard digging, ditching, and rock configurations.
Hydraulic hammers
The machine is suited for hydraulic breakers in the 1.5 to 2.5 ton weight class. The 47.6 GPM (178 LPM) pump flow supports standard medium-pressure breaker operation without requiring high-flow auxiliary circuits.
Quick couplers
Compatible with both mechanical and hydraulic quick hitch systems. The machine's 19,291 lbs (8,750 kg) operating weight provides sufficient stability for standard coupler attachments.
Thumbs/grapples
Hydraulic thumbs and grapple attachments are available for this model. These are typically mounted to the stick or bucket pin interface to enhance material handling capabilities.
Rippers
Single or multi-shank ripper attachments are supported for the PC95R-2. These are designed for breaking up hard soil or rock surfaces.
Hydraulic-kit notes
Standard auxiliary circuits operate at the machine's rated system pressure. No high-flow auxiliary circuit is required for standard breaker or auger applications. Komatsu EO or TO hydraulic fluids are recommended for the system.

Frequently asked questions
What engine does the PC95R-2 use?
The PC95R-2 uses a Komatsu 4D106-1FB diesel engine with 4 cylinders, 269 cu. in. (4,413 cc) displacement, and 82 HP (61 kW) net power.
What is the operating weight?
The operating weight is 19,291 lbs (8,750 kg).
What model replaced the PC95R-2?
The PC95R-2 was replaced by the PC95MR-2.
What PC95R-2(S/N 21D5200330-Up) owners discuss
What engine model and power output does the PC95R-2 use?
The PC95R-2 is powered by a Komatsu 4D106-1FB engine. This four-cylinder unit displaces 269.3 cu in (4.5 L) and produces 82.5 hp (61.6 kW) at 2200 rpm. Maximum torque is 228.7 lb ft (310 Nm) at 1500 rpm. Variations in net power may occur depending on the specific configuration or regional emissions package installed on the machine.
How does the hydraulic system behave under load, and what are common failure points?
The main hydraulic pump delivers 47.6 gpm (180 lpm). A common diagnostic pattern is weak performance when hot but normal operation when cold, which indicates internal leakage in the hydraulic pump, main control valve, or cylinders rather than pump failure alone. If all functions slow simultaneously, check hydraulic oil level, filter condition, and engine RPM. If only one function is slow, inspect the specific cylinder, control valve spool, or hose restriction. Owners report that contamination and extended service intervals accelerate wear on these components.
What are the typical undercarriage wear patterns and specifications?
The machine uses a track gauge of 5.9 ft (1800 mm) with 44 shoes per side. Standard shoe width is 17.72 in (450 mm). The undercarriage includes six track rollers and one carrier roller per side. Common issues include tracks loosening repeatedly due to tensioner failure or excessive wear, and the machine pulling to one side if track tension or roller condition differs between sides. Mud or debris packed into the undercarriage can also cause uneven travel speeds.
What electrical or sensor issues are frequently reported?
Komatsu excavators rely on electronic control systems where a single faulty sensor or unstable power supply can trigger multiple warning signals. Owners report intermittent starting, dashboard failures, and random shutdowns. A common specific issue is the temperature buzzer buzzing continuously even when the engine is cold, often caused by a faulty temperature sensor. Always verify battery state of charge and chassis grounds before diagnosing complex electrical faults.
What should be checked when buying a used PC95R-2?
Verify the exact serial prefix to confirm the correct engine and hydraulic specifications, as configurations vary by serial range. Check for engine overheating during heavy work, which may indicate clogged heat exchangers or a failing head gasket. Test all hydraulic functions cold and hot to identify internal leakage. Inspect the undercarriage for uneven wear and track tensioner integrity. Ensure the cooling package (radiator, hydraulic oil cooler, charge-air cooler) is clean and free of packed debris. Confirm the battery holds voltage under starter load.
How does the engine perform under heavy digging loads?
The engine may idle normally but lose power when combining boom, arm, and bucket movements. This can indicate airflow restriction (clogged air filter, damaged charge-air hoses), fuel system issues (clogged fuel filters, water in fuel), or excessive hydraulic load dragging the engine down. Check the engine RPM under load; if RPM drops heavily, the hydraulic system may be overloading the engine or the engine may be unable to produce expected power. If RPM remains normal but movements are weak, the hydraulic system is the likely cause.
What safety-critical fixes require dealer verification?
Swing brake release system integrity and swing motor holding capacity must be verified by your dealer to ensure the upper structure does not drift or fail to hold position. Final drive oil levels and contamination checks are critical for travel safety and must be performed by your dealer. Any repair involving the hydraulic pressure regulation or engine governor settings requires dealer verification to ensure safe operation.
Compiled from owner and technician discussions across the industry — experiences vary by serial range and machine history.
