This past weak I done the 300 hr. service on my BX2350 changing all the fluids and filters. When I installed the new Kubota oil filter I had noticed that it didn't feel quite right going on. So I removed it and gave it a quick look over and didn't notice anything unusual with it. So I reinstalled it after all it is a genuine Kubota part. I started the tractor up with out the front end on and checked for leaks, no problem. Reinstalled the hood and brush bar and started it up again and let it run for few minutes. Then I noticed oil dumping out on the floor so I quickly shut it off. The new oil filter had blown loose. I then removed the filter and gave it a closer examination. Threads on the filter mount looked good but the threads on the filter were flat 3/4 of the way around. I did not have a nother filter and didn't want to drive all the way to the dealer so I picked up a couple of Wix filters at local auto parts store. After comparing the filter that had blown off with the new Wix and the Kubota filter that I had removed. It was clear that the threads were not machined right. I checked the threads with a pitch gauge and the pitch was fine, just they were less than half the depth 3/4 away around the hole. I guess quality control missed that one. I thought I would post this so others might take a closer look when changing filters. The Wix filter number is 51365 and looks to be of a lot better quality. Here are some pics of the filters I don't know if there good enough to see the threads.
