2023 Doosan DX340LC-9C Crawler Excavator

It was a very hot afternoon, and I spent about half an hour inspecting this excavator under the scorching sun, carefully checking many details. The Doosan DX340LC-9C orange paint and freshly cleaned, but underneath that doesn’t say it all, it’s about what’s under the paint. Popped the hood for the engine compartment and it’s all like new, no oil mist on inside engine room panels, no weep around the valve covers and fuel lines…ok, hoses smell new. At the same time, no traces of oil leakage were found inside the engine compartment. No pitting, no rust blooming, no weeping or crusty seals (which would be an issue if the boom and stick had not been moved in quite awhile before it was delivered onto the job site), no leakage from hydraulic rams on boom and stick.

Undercarriage is a good indicator if someone is “bullshitting” the number of hours, but this is a clean as can be—90-95% life on the tracks, maybe even more, idlers have no side to side “slop”, tested the sprockets and the teeth are sharp and not blown off enough to be a problem, tested the heights of the greosers and there is almost as much greosers as the original, no hammering noise when I had the operator cycle it around me while standing underneath and testing the pins on the idlers were tight. The tension on the tracks appears to be factory and not over tight, as some retards have done in order to make them look less worn.  The seat pocket is empty (excluding the warranty) of any Operator’s Manual, which is stupid as it’s the first place a buyer would look but not my problem. It started up without smoke, idled nicely, hydraulics sounded very nice as the sticks were feathered, the buckets had good curl and no stuttering and the pumps were good without cavitate noise. Normal tight fit (no slop) on pins on the bucket linkage. Machine digs well. No play. Cloudy throughout, made things more difficult in finding the defects in the paint and there were none that I could see, there were a few minor scuffs on the counterweight (due to shipping) of course. Overall this one its clean, not more than 500 hours if not less.
