MF165 Diesel Leaking Into Motor Oil
i believe the 65 could have a hydraulic power steering pump on the timing cover but if its the kind im used to it would be empty with about 2 quarts and u wouldnt have power steering and the oil wouldnt get any fuller. as everyone knows with the rotary pump it could be the front seal goin bad. or like the other guys said about the preheat or injectors. but if its fillin up that fast it must have a big hole to enter through, like the front pump seal
I do know the seals in the hydraulics are wore out. Funny cause the rear 3 point is weak as hell and it's the primary system. The end loader will still hold plenty of weight in the air even with the tractor off but it's on the axillary hydraulics. Don't make no sense to me, I'd think it would be the other way around. This little tractor moves 1800 pound round bales around on that front end though.
Thanks all. Been to damn muddy to get out there and look at this yet but as soon as i can I'll check out this pre-heater fuel line and give that a shot. Sure do hope it's somethin this simple.
Hey Steve, you bet I can. I'll snap it tonight when I'm out there to feed. I got the hood and side panels all pulled off of it right now so everything is easy to get to and see.
I'm not familiar with that pump, if you are sure it is fuel..probably the transfer pump. On some rotary inj pumps the front seal goes out and it will fill the crank case with fuel aswell.
Not sure if it's fuel or hydraulic fluid myself and don't know how I could tell the difference without an oil analysis. They smell and look close enough alike that it would be hard to say.
If you pit a drop of engine oil on a napkin , if it has fuel in it it will wick out ward pretty quick.
The powersteering pump that sits below the inj pump has a pretty small res on it..it should be pretty obvious if the level is droppin. I bet it is fuel unless there is a hyd pump bolted to the engine on the right hand side. Keep in mind that i am a Deere Tech and don't work on other brand stuff so maybe i am missing some thing here??
