TC 33D Hyd leak from weep hole

It sure does look like the HST linkage.

It is indeed the HST linkage. In that cropped picture you can just barely see it, but the spring that returns the pedal to neutral is in that round sleeve.

Did you end up getting your leak fixed? I have something very similar going on with my boomer 35. Trying to figure out where the leak is coming from on the hst before I split the tractor. I had a huge mouse nest inside the case of mine too and I was wondering if that could have something to do with the leak so after reading this I’ll be sure to check that front seal. Couldn’t believe there was a mouse nest inside there.

The plot thickens. Finally was able to reach the dealer (I had been to this one before). Talked to their service manager. He was pretty familiar with the problem. Believes it is the seal on the input shaft to the HST pump. Without prompting he told me that what happens on these machines is that the "dry space" where the pump is gets sometimes filled with grit grime etc. because there is a golf ball size "inspection" hole at the top of that casting. Worse yet, he said that rodents sometimes get in this space and fill it with more debris. This gets onto the input shaft and works its way into the seal, and destroys it.
It was then that I told him that I had been pulling sludge and acorns out of an access point that was created by my removing one of the hard lines that goes into this housing. What a stupid design (new Holland) that allows this to happen. Sure have a vent/inspection hole on top of the casting, but have a damn screen over it to prevent this!!

Anyways, If it is just the seal, the approximate cost for the whole job is 2 to 2.5 k. Mostly all labor to get to everything (splitting the tractor and putting it back together.. I was expecting this (actually was expecting a good bit more). They could schedule the job at end of June. I was going to do it myself, Now I am back on the fence...
