Im operationg a Kobelco ED150 Excavator in cold weather (-30 deg. C). I left the machine run over night due to the cold weather (idled up at 1100-1200 rpm) and in the morning I have engine oil leaking from a stump pan and sitting on the frame. Is there an oil breather allowing oil out (that I cant find) or is there a more serious problem. The machine had no engine leaks prior to this.
There is a crankcase breather on every diesel engine. Just look carefully. The seriousness of the problem depends on the source of the leak on the engine. Why did you leave it running overnight? That sounds crazy to me. I can see 20-30 minutes warmup time in cold weather like that, but overnight sounds excessive to me. Also, I would start gradually warming up the hydraulics in the air after 15 minutes of letting the engine warm up. Just running the engine without working the hydraulics doesn't warm up the hydraulic system very well, and it needs warming up just as much or even perhaps more so than the engine.
The breather must be concealed somewhere not first readily viewable. Ive poked aound in there and no luck. Waiting for a call from Kobelco on where the breather is exactly. The leak isnt hydraulic and yes, of course they get warmed up and cycled before any vigorous activity occurs. My question is about engine oil. When its this cold its common practice to leave equipment running over night. Im in and out of the machine 24hrs a day.
i don't know about you're oil leak. but i do know i would rather put a concrete blanket over my motor at night at those temps. then show up early and light up the top hat, or weed burner. just my 2 cents.
On USA models i think the breather is plumbed into the air intake because of emission regulations. On graymarket machines there is a hole in the pan with a short hose about 3/4 inch diameter sticking out about 2 inches.
Thanks DirtHauler... Ill have a closer look in both of those areas!
I just say, Webasto!! http://www.webasto.com/products-and-markets/offroad/en/html/7977.html
Well I found that dirty little breather. Its on the opposite side of the motor where the leak is coming from, so thats ruled out. The darn thing pipes out from the side of the block up into a filter housing bolted onto the exhaust manifold and straight down through a stump pan. Thanks again DirtHauler
hi meaney, i agree with some of the posts, leaving the machine running all night unattended... you're taking huge risks. if you ed150 has an auto-warmup option it will cycle and load the engine/hyd. if a hyd hose was to blow...the hyd tank will empty in minutes. you'll fry the pump. there are other options such as as diesel fired block heater system set on timers. then you can program to kick in an hour or so before you arrive at the machine. less risks. the most common spot to check, 9x out of 10, is your engine oil pressure switch. should be hidden on the side of the engine block tucked below the fuel inj pump, i believe on the counterweight side. they tend to leak out the stem and the fan will spray it all over the engine making it harder to pinpoint. cheers!
