B6100D Coolant leaking

[bomberal]

Water is dripping from behind the oil sump onto the front diff.
It is impossible to see where it is coming from.
I have checked the radiator and hose and neither is leaking.
Where could the water be leaking from and how can it be repaired?
Any help or suggestions would be appreciated.

Welcome to the forum. I just watched the Australian Open. What part are you at?

I live about 2000 kilometres (1200 miles) north of Melbourne just north of Byron Bay at a place called Billinudgel.

Hi. And welcome to the forum. Re your coolant leak, have you taken the radiator off yet to have a better look. That's about all I can suggest. I know it is easy enough as I did it myself on my "new to me" B6100D this past summer (here in the northern hemisphere.) I read in this article (http://www.orangetractortalks.com/2010/02/tips-for-the-new-owner-of-a-used-kubota/) that one of the first thing to do after buying a used tractor would be to replace the radiator hoses. If I can remember it's just a matter of removing the 2 nuts that hold the hood on, then opening the valve on bottom of radiator to drain it, loosening the nuts on the clamps that are used to attach hoses to the radiator, and then finally the 2 nuts on the bottom of the radiator that attaches it the tractor itself. Good luck.

It sounds like it's leaking from the Gear Case Cover (front of the motor), there is only a couple of connections and places for it to leak.
If you don't have it go to Kubotabooks.com and down load the three part WSM for your tractor , it will give you more insight to what's under the hood.

Thank you for the replies and suggestions. I will follow through on them at the weekend and report the outcome.
I haven't yet removed the radiator as the leak is only apparent at the rear of the engine and everything appears dry around the radiator and the hoses.
I was wondering if there was a plug or some water connection at the rear of the block or head against the firewall which seems impossible to access without major dismantling.
I have accessed the downloads from kubotabooks.com and will study them particularly the Gear Case Cover.

I am curious as to why you think it's leaking out somewhere in the rear of the motor, if it is indeed leaking onto the front diff and axle case it's almost has to be the front of the motor leaking, as the rear would just leak onto the ground.

I stand corrected. Yes the water is coming from the front of the engine.(see attachment). Both upper and lower hoses seem sound as does the radiator so I guess it must be eminating from the gear case cover as suggested.
Can you please tell me what that may indicate and how to fix it.
