3540 Hydraulic leak

[hunt4570]

Mine is a Jan 2012 build and the trans input shaft seal was the leaker, not the 4x4 shaft which is 3 inches lower not in the photo. It was the early style seal. This one:

The newer tractors already have the 4 by shaft seal fix in them from the factory..

Sounds like the same issue on the same year tractor, maybe a second opinion is warrented?

I would probably think the same, but this dealer's workshop isn't about to dive into my tractor to drive up their workload for shop income. They have plenty of valid work to do, to include new tractor sales prep. They move a lot of equipment. I'll relay exactly what they replaced on the invoice when I get it back. I want to make sure I'm correctly explaining what seal they are replacing. I'm just hoping this fix will last longer then the 375 hrs this one lasted.

I've got like 1100 or so hours on mine now, I bought it used with 320.

On my 2012 there was an updated seal for the HST input shaft. The new seal was double lipped and the one I removed was a single lipped design. Also the seal housing has been updated to a heavier design. The price for the parts was relatively cheap.

My tractor is now repaired. I was about to change the HST hydraulic fluid and filters anyway so the timing worked out when they split the tractor and had to remove the fluid. Here's a copy of the invoice showing parts used. I already compared Hunt's seal kit number to my invoice, it's not on there.
I believe my leak was on the transmission side. When the service rep called me stating they had to split the tractor, he stated my tractor already had that updated seal. Hopefully, this will solve the problem for many thousands of hours into the future.
