The Komatsu PC75UU-2 and Its Compact Excavator Lineage
The Komatsu PC75UU-2 is part of Komatsu’s PC series of compact hydraulic excavators, designed for urban construction, utility trenching, and tight-access excavation. Komatsu, founded in 1921 in Japan, has long been a global leader in earthmoving equipment. The PC75UU-2 was developed during the late 1990s and early 2000s as a zero-tail swing machine, allowing operators to work efficiently in confined spaces without the rear of the machine extending beyond the track width.
This model features a boom offset function, a compact footprint, and a cab-forward design that enhances visibility and maneuverability. With an operating weight of approximately 7.5 metric tons and a bucket capacity ranging from 0.2 to 0.3 cubic meters, the PC75UU-2 is well-suited for residential foundations, roadside work, and small-scale demolition.
Terminology Clarification
Komatsu does not publicly publish a comprehensive serial number-to-year chart for compact excavators, unlike some manufacturers. However, dealers and service technicians often maintain internal databases or reference guides that correlate serial ranges with production years. For the PC75UU-2, serial numbers in the 8000–9000 range typically correspond to machines built between 2000 and 2002.
For example, a unit with serial number 8711 would likely have been manufactured in 2002, assuming standard production sequencing. This aligns with Komatsu’s global production timeline, as the PC75UU-2 was phased out in favor of newer models like the PC78US-6 and PC88MR-8 in the early 2000s.

Conclusion
Identifying the year of a Komatsu PC75UU-2 by serial number is a critical step in evaluating its value, compatibility, and regulatory status. While Komatsu does not offer public serial-year charts, experienced dealers and technicians can provide accurate guidance. With proper verification and maintenance, the PC75UU-2 remains a capable and efficient excavator for compact job sites, even decades after its initial production.

Terminology Clarification
- Serial Number: A unique identifier stamped on the machine’s frame, used to trace production year, configuration, and factory origin.
- Zero-Tail Swing: A design where the rear of the excavator does not extend beyond the track width during rotation.
- Boom Offset: A feature allowing the boom to pivot independently of the upper structure, useful for digging alongside walls or obstacles.
- Hydraulic Quick Coupler: A device that allows rapid switching between attachments without manual pin removal.

Why Year Identification Matters
Knowing the production year is essential for:
- Parts Compatibility
Hydraulic components, engine models, and electrical systems may vary between production years. Ordering the wrong part can lead to delays and installation issues.
- Resale Valuation
Buyers often assess age alongside hours and condition. A 2002 machine with low hours may command a higher price than a 1998 unit with similar wear.
- Regulatory Compliance
Emissions standards and safety requirements differ by year. Machines built after 2000 may fall under Tier 2 regulations in North America or equivalent standards elsewhere.
- Maintenance Scheduling
Service intervals and recommended upgrades may depend on production year. For example, early models may benefit from hydraulic hose replacements due to aging rubber compounds.
If you’re evaluating a Komatsu PC75UU-2:
- Locate the serial number on the frame near the cab or engine compartment
- Contact a Komatsu dealer with the serial number to confirm production year
- Request a service history or maintenance log if available
- Inspect hydraulic lines, swing bearings, and undercarriage components for wear
- Verify engine model and emissions compliance if operating in regulated zones

Identifying the year of a Komatsu PC75UU-2 by serial number is a critical step in evaluating its value, compatibility, and regulatory status. While Komatsu does not offer public serial-year charts, experienced dealers and technicians can provide accurate guidance.
