2020 SANY SY485H Crawler Excavator

Today we’re inspecting this Sany 485H heavy-duty excavator – it has been working, no doubt about it, the undercarriage shows it, the wear is cumulative from the link tension and the lack of flange collapse is good, but the tension is also stretched out a bit and the grousers still have some life in them but probably 60 to 65 percent lifetime left on the tracks – wouldn’t push it any further, anyway, without getting up close and personal with the bottom rolls as some guy in the yard next to them was trapped in a dump truck, blasting music for the majority of the time I was there.

That’s a real number, hours screen read 4991 — call it 5000 even — to date-stamp live on the dash June 9 2025. When I arrived there fuel was low, just that they didn’t fill it up, whatever. I would like to see how the coolant temp was, it was high, 100 to 110 out of 120 on the temp gauge and then I would want to see it before running it hard, because it is just full of dirt in the radiator cores, both the radiator main core and the a/c condenser side, it has never been blown out due to it being too full of dirt. Popped the side panel on the main pump bay, on the outside of the pump housing it’s dry, but if someone put it up on a lift there is dark wet staining on the frame floor that is not fresh dust, it’s seepage, but a slow seepage — it could be the swing motor seal, could be a fitting weeping somewhere on the main pump circuit — I couldn’t catch the source while standing there. Engine bay up top is not nearly so bad as I thought — valve cover is dry, no top end weep (which surprised me), and the turbo looks good with no damage to the silicone on the intake (which I thought it would be), but the exhaust manifold is super rusty, but that’s just heat cycle and age, no big deal there. Not damaged, it’s just a mess. Floor was with mud and grime ground in: door sill’s beat up; race seat (normally found in a street car) was still in place which does nothing for the car, but it was there; a/c panel was showing auto set to 18 degrees, so the a/c system’s present, there was a sany radio in there with the six presets still programmed. There was no disappropriation of lease or joysticks chewed by the controls, no cracked levers, etc., either. Standard worn Bucket Teeth – replace.
