Had in interesting experience yesterday. Was out using the tractor to finish up some culverts, moving stone with the backhoe, pushing deadwood and old logs out of the way for a shed pad, and generally tractoring around, when I looked over my shoulder to see black smoke belching from the exhaust. Not good. Thinking it might be loading up somehow, as I was running the hoe at about 1200RPM, I tried revving the motor up a bit to see if would clear up. No Bueno. Black smoke became white smoke, even more no bueno. As I was turning it around, the motor went runaway, and I just stalled it out to shut it down.
When I pulled the dipstick, the oil level was all the way to the top of the stick. Obviously way too high and the source of the runaway feeding frenzy. On the plus side, the 1 acre white cloud of smoke kept all the bugs away for the night.
Came back today, drained crankcase, refilled with oil to between the marks, checked the air filter (it was fine) and got it to fire. It eventually cleared up and ran fine after 5-10 min. Where did all the oil come from? There appears to be a corresponding loss of oil on the transmission dipstick (gear model)
Which leads to my question- Is anyone aware of any other way for UTF to enter the crank other than via the front of the hydraulic pump? There does not appear to be any other hydraulic interface with the motor save the pump itself.
I've been having some weird hydraulic issues with the front loader, where it starts going spongy after warming up, so I'm focused on the pump as the culprit.
Any ideas?
