2020 Doosan DX500LC-9C Large Crawler Excavator

My first impression was the scania having walked this machine yesterday afternoon, right engine for a 500 Class machine, looks bad external but don’t judge a book by it’s cover, no oil around valve cover gaskets, no cracks or soft spots in hose found. Engine bay is messy as it gets in any operation, but I carefully searched it and found none of the oil fresh and none wet at the fuel filter base, bowl of the water separator was also clean with no contamination laying in it. When I arrived Machine was running, but not idling and did not make an audible knock while idling from ground level. All these are you can verify without laptop.

I really like this Doosan DX500LC-9C excavator.The undercarriage is where I’d start with if I wanted to purchase this pickup. You’re tracking to profile 50 or 60 percent life left on grousers, if you’re still getting use out of these, I’d say they’re just walking the walk for the next major contract—you need to have a discussion with your equipment supplier about replacement rates before you can even consider it going into the ring with you again. The sprocket’s teeth are not yet hooked, so that’s something as well, meaning there was no idiot that let it go stupid far over the service life. Annoyed that his rollers and idlers were covered with dried up mud and the operator didn’t provide an opportunity to get a clear shot of the seal faces, but nothing was seized and the machine tracked in straight when the operator moved it around. Pins feel tight. No slop. Well, let me go look at what I jotted down about the pump bay… okay, I revised twice just by virtue of seeing how the travel motors are normally, there’s always that “honey thing” on the ones that are a little greasy and it looks like it’s oiling out but when you pull it back there’s just old crud, old dust and oxidation, no fresh oil—both motors appear to be in good shape.The wear on upper structure rear and the counterweight is quite bad with peeling paint—big sections of bare metal on there, and there’s even a company decal on the side panel china railway 18th bureau, big civils contractor, this had been on serious earthworks which is what you see everywhere generally. If your bucket teeth are flat, even though they’re on, but not sharp, save money for a new set before installing it on anything you need them to be sharp on.  Here you’ve got a few items in your negotiating toolkit: bucket, undercarriage and paint. Everything seems dry under the hood and with the hydraulics.
