Komatsu PW210-1(S/N 10001-UP)

The Komatsu PW210-1 (S/N 10001-UP) is a roughly 19-tonne class wheeled, rubber-tired hydraulic excavator built for road-mobile digging work such as utility, sewer, water, and municipal jobs where the machine needs to travel between sites under its own power rather than ride a trailer. This S/N 10001-UP block covers the entire -1 series production run with no follow-on alpha-prefix split, so parts and documentation track cleanly against one serial band. Power comes from a Komatsu S6D105-1 turbocharged inline-six diesel rated at 114 kW (152.9 hp) gross at 2100 rpm, mechanically governed with no engine ECM and no KOMTRAX telemetry, the same engine family Komatsu fitted to the contemporaneous PC200-3/PC220-3 crawler excavators. Operating weight is about 18,980 kg (41,844 lb) for the reference configuration, varying with boom/stick length, bucket size, and blade or outrigger fitment; Komatsu offered the PW210-1 with a shorter and a longer stick on a common boom, plus a front leveling blade and outriggers as options. It sits above the PW200-1 in the model line, sharing that machine's wheeled chassis architecture: an oscillating front axle, a center swivel joint, and a powershift transmission with two forward and two reverse gears.

Komatsu never carried the "210" designation past this -1 series. The size class was absorbed into the PW200 and PW220 lines that followed as Komatsu moved through later-generation wheeled excavators with electronically controlled engines and, eventually, KOMTRAX telemetry. That leaves the PW210-1 as a mechanically simple machine: no engine electronics to fail, no aftertreatment to service, and a drivetrain and hydraulic system a generalist shop can diagnose with test gauges instead of a laptop. In the used and parts market, that simplicity is the draw. These units mostly worked in municipal and utility fleets that ran them for years on sewer, water, and roadwork, and owners keep them going because rebuild parts for the engine, axle, and hydraulic pump and valve interchange with the wider S6D105/PC200-3 parts pool. Buyers should expect wear concentrated in axle kingpins and oscillation bushings, the center swivel joint bearing, and boom/arm/bucket pins from years of tight urban digging, plus the usual wear items of a mechanically injected diesel's fuel and turbo systems.
