John Deere 2520 Anti-freeze Leak

[byak651]

Had an intermintant leak where would see a couple drops under the front of the tractor on occassion, didn't always happen. Couldn't really see where it was coming from, made sure everything was tight and just kept an eye on coolant levels. All winter for snow plowing never noticed it, but last week used it when it was a little warmer and next day was a pretty good leak under it. Closer leak looks like coming towards top of water pump. Any ideas. Started taking it apart, don't have a service manual but have radiator, fan, miscellaneous off. Pump spins by hand with no binding, wondering if it might just be a gasket? Will try to finish getting the pump off today or this week but just seeing if anyone else had this happen and what they did to fix. Also if anything I need to pay attention to when taking the water pump off.
Thanks.

Well only 20 minutes or so since replacing 3 gaskets and no leaks, hope this was the issue. With no service manual took about 2 hours to disassemble, week to get parts shipped on line (approx $35) and another 3 hours or so to put back together. This was the problem

I just had the same issue with my MY2011 4720. took it to the dealer. dealer said JD's repair recommendation is to remove the original sealant (glue?) and replace with paper? (regular) gasket. once done, there's been no more leaks. No warranty...they made me pay.
