Is your 4720 "making" water which makes it look like it's making oil? If it had water, wouldn't it be at the bottom of things and hard to find? Hows the coolant level? I guess what I'm trying to figure out is if you had water introduced into your crankcase, how do you detect that since it should sit at the bottom?
Maybee you have oil colored water (kinda like a "Grail shaped Beacon", if that reference makes any sense...)
That was my first thought but I would see the oil and water separate on the towel when I check it. Diesel will wick faster than motor oil. especially with this much of a difference?Could be a leaking injector
"I bought my 4720 mid 2009 and within 12 months had the same problem, ie oil level increasing. Transfer pump changed under warranty. Problem continued. In November this year agent took tractor in and sent oil sample off for analysis which showed it was diesel in the oil. They again replaced the transfer pump and seal on the side. Some comment from mechanic about low sulphur not bedding seal properly but low sulphur diesel has been around for years. Tractor returned last week and has been used once since and there looks to be an increase in level of about 6ml. Our observation is that the harder the tractor works the higher the level. Tractor has low usage and has only done about 180 hours work in two years. I am continuing dialogue with the agent as I am not comfortable with the situation. Rob"I know, its not possible. Well, its happening. My oil level keeps rising a bit above full. At this point I am a solid 3/8" above the full mark. It makes no sense.
I have done the paper towel test to look for other fluids or fuel, it comes back perfect, no wicking or color difference at all. The oil looks great.
All I can do at this point is change the oil and see. I might have an analysis done, but one would think a new engine would use it, not somehow increase the amount.
I have to take it over to the farm tonight and remove the skinny tires from the 1586 and put on the fat duals. (we bought a used 8300 and are selling the 1586) so I will keep checking it as we use it.:unknown:
Hey Brian the newer diesel oils will hold the diesel so the "paper towel test" won't show anything. If it does turn out to be diesel be careful it is not an injector as it can burn a hole right through the piston.
That one had a bad hydro pump and the hydro oil got in the crank. They replaced the pump and all was good.I heard of this problem on one here a 4720 with 8hrs on it. I forgot the solution.
