Hi All...newly registered user here so this is my first post...and sorry it has to be so lengthy. I've been watching threads here for a while but have had nothing worthy to post so didn't register previous. Now, I have an issue that others may want to hear about.
I last changed my transmission fluid/filter and cleaned suction screen/magnet in May of this year at 277 hrs. I've been mowing all summer and watering trees with no issues (without loader frame being mounted) and now have about 330 hrs. I finally had use for the loader a few weeks ago so first removed mower deck and mounted the loader. The first time starting the tractor after the loader was mounted I noticed a stream of fluid all over the garage flow so I quickly shut off tractor. Upon examination, I noticed the hydraulic filter seal had blown. I cleaned up the mess, removed filter, put on a new one, filled fluid, and restarted tractor. Let tractor run for several minutes as I exercised the hydraulics (loader). No leaks, good to go. Shut off tractor to eat lunch. An hour or so later I restarted tractor and immediately started seeing fluid all over floor. Same exercise....clean up mess, replace filter, refill fluid...this time questioning did I tighten the filter enough. Pulled out book and specs say tighten 1/2 - 3/4 turn after gasket contract...good to go (did you know that the filter box indicates 1 full turn?). Started tractor and again, no fluid leaks. Let tractor sit again for a while. Later came back to start and again was blowing fluid all over floor. Again, questioning if I overtightened the filter I went to my local dealer to pick up additional filters and fluid....same results. This time I bagged my filter so I wouldn't drop fluid all over floor and winched tractor onto my trailer and took to dealer.
At dealer, I showed pictures of filter as it was on the tractor showing bulging filter. There the service manager accused me of overtightening the filter...saying that is the only way that issue could happen. I told him that wasn't the case...that I've been changing fluids/filters longer than he's been alive. Left my tractor and the next day they were able to get mine in the shop. They replaced the filter and tested pressures in several different locations (not sure where all...but there is a place under the seat behind the panel by your boot heal) that was also tested. All tested within specs. So, after $500 of parts, fluid, and testing labor, they found no issue. I loaded the tractor and placed in my garage. Two days later it's time to mow. Removed loader and mounted mower and mowed for 2 hours...no issue. Parked tractor in front of garage on newly poured concrete and went into house to eat lunch. About an hour later I go back outside to remove the deck and remount the loader....and upon starting I'm blowing fluid again. Pissed my off....all over my new concrete. Loaded tractor and back to dealer...told service manager that it was their mechanic that put this filter on...and that he owed me an apology for accusing me of overtightening. He never said a word...but had someone else get the mechanic that did the original work.
The mechanic apologized and couldn't understand what had happened. He was going to open a Dtac(?) with John Deere to help solve this problem. Well, that was this past Friday and I've not heard a thing.
So, over the past 2 weeks, I've blown gaskets on a total of 4 filters. In each case, when the filters blow, it is immediate upon start up. I'm getting no drips on the floor between the prior shutdown and the startup that blows the filter. I have not pulled the oil suction screen/magnet again to see what this looks like.
I plan to stop by the dealer today to see what progress, if any, that they've made. Anyone have any ideas/thoughts that I can bring to them?
