FAQ

Question Does this Parts List cover my specific machine version and engine type?

Answer Yes, this professional document explicitly covers the Kubota KX161-3 excavator series starting from Serial No. 00001 and Up. It is fully applicable to regional configurations including KBM (Standard), KE (France), KDG (Germany), and KUK (United Kingdom). The manual provides deep-level data for the Kubota V2203-M-EBH 4-cylinder diesel engine, ensuring you have the exact identifiers for internal components like the 1A085-0101-3 Crankcase or the 1G787-5101-0 Injection Pump. Having these specific serial-matched part numbers prevents the common mistake of ordering incorrect components for different production years.

Question What are the critical torque and service benchmarks for the hydraulic and engine systems?

Answer Maintaining factory-spec pressures is vital for machine stability; this guide references a main relief pressure of 3,553 PSI (24.5 MPa) to ensure your hydraulic pumps operate within their intended safety envelope. For engine top-end work, specific torque values such as 70-75 lb-ft for cylinder head bolts and 33-36 lb-ft for connecting rod bolts are essential to prevent head gasket failure or catastrophic bearing seize. Additionally, setting the cold valve clearance to the precise 0.18 - 0.22 mm range ensures optimal compression and prevents long-term engine overheating.

Question Can I use this manual to troubleshoot complex fuel injection or cooling issues?

Answer Absolutely. The manual details the entire fuel delivery circuit, including the 16454-5390-0 Nozzle Holder and the 19077-5371-4 Injection Pipes, allowing you to identify exact seals and washers (like the 15841-5362-2 Gasket) that cause pressure drops. For cooling, it covers the 1A051-7303-2 Water Pump Assembly and the 15321-7326-0 Thermostat Cover. By identifying these specific factory codes, you can resolve "hard start" issues or engine "hunt" by ensuring the injection timing remains at the factory-standard 17° BTDC.

Question Does the manual provide enough detail to rebuild the track and drive systems?

Answer This technical guide provides high-density exploded views for both 400 mm Rubber and 550 mm Wide Iron crawler tracks. It breaks down the S111 Idler, S112 Track Roller, and the internal components of the S044 Drive Motor. Understanding the assembly of the 15521-2353-0 Side Metal or the track tensioning springs ensures that you can perform a full undercarriage overhaul to factory standards, which prevents expensive track derailment and premature wear on the drive sprockets during heavy excavation.

Question How does the digital PDF format benefit me during a live repair on the shop floor?

Answer The high-resolution digital format allows you to zoom in on complex schematics, such as the S054 Control Valve component parts or the S041 Electrical Wiring harness, with photo-grade precision. This level of detail is critical for identifying tiny internal parts like the 07715-03213 Ball in the gear case or the 15221-1315-0 Valve Stem Seal. Instant access on a tablet or smartphone means you can verify the orientation of seals and clips while standing at the machine, drastically reducing the "back-and-forth" time between the workshop and the parts counter.
