Have a 650j deere dozer, lower serial, has 6500-7000 hrs. Lost oil pressue, getting some oil clear up to turbo. have put manual gauge in galley with no results. any ideas?
What does the oil look like? What's the level, it's not all the way up to the turbo, is it? Any chocolate color to the oil? Have you tried loosening the drain plug to see what seeps out? Did this happen gradually or suddenly, and what's it sound like?
Hello Delmer oil has about 200hrs on it, and is up to level! Happened suddenly. There is no contamination, It has oil all the way up to the turbo, but it has no pressure, checked with 2 manual gauges, Thank You for any help You can offer. Greg
If you mean that oil flows out of the turbo supply when you crank it, then I suppose the pump is turning, and it could be a leak somewhere. Maybe the oil relief valve, but it looks like you have to take the timing cover off the front of the engine to get at that. I'd start with pulling the oil pan to see what you can see of the oil pump and pickup, but I don't know how easy the access is for you, and I'd wait for a more qualified second opinion before you dive into that only on my advice.
Already pulled the pan and that all looks good, I am going to put new o rings and seals on everything and try it out! Thank You for responding!
Did you check if your oil pump gear has spun on the shaft?
Had an oil pump shaft snap off in a JD engine once.
Gear on shaft is good and tight! Thank You!
That's all good, Thank You!
