New Holland TC 31 hydrostat oil leak

[Dog doing]

I have an oil leak in my new Holland coming from the dry case that houses the hydrostat pump .
I have Split the tractor and the cause of the leak it’s not obvious.
I am convinced it’s not the O-rings from the feeder lines . are there any new Holland owners out there with the same problem?.

Have you checked the transmission input shaft seal? Is it a slow leak or a fast leak?
