Engine oil leak

[SidecarFlip]

Front crank seal maybe? Easy replacement.

My oilpan is weeping. I have never lost any that I could tell on the stick. At my 400hr recently, I really washed it good to see where it is coming from and I can't tell. It isn't enough for me to ever see a drip.

I will ask my dealer about it. I would not want to go a month without my tractor.

The only engine oil leaks I ever see on a B series are the engine oil pressure sender and the tach drive gasket. I service on average 1 or more a week.

They have replaced my oil pan and the same leak is still present. It looks like its coming from the front engine cover Behind the frame.

It’s dry in that area. It looks like it’s from the front engine case gasket.

Where are these located?

Where are these located?

Tachometer drive is on the front of the engine, engine oil pressure sender is on the left front of the engine block.

my leak seems to be coming from the lower part of the front engine cover. I’ll try again to find the areas on the parts diagram you mentioned.

Think I may have found my issue. Kubota issued a new gasket for the gear case cover. This is where mine is most like leaking from. Part #130

Picked up my tractor today. Kubota sent a rep/tech up to help diagnose the leak. They verified the gear case wasn't warped and instructed the tech to replace the gasket. The service department stated they had another B2650 come in with the same leak recently and need to make the same repairs.

My LX2610 recently developed a leak in the same location. I'm going to look into the oil pressure sending unit that @whitetiger mentioned and if thats not it, get it in to have it repaired.

What did you find leaking?

What did you find leaking?

Ironically, after cleaning everything up last spring to identify the source, it stopped on its own. Going to continue to monitor, but at the moment, there is no leak to speak of.
