i'm changing the hydraulic filter on my 3301dt the dealer gave me filter HH32-16770. i opened the box at the parts counter and said this one has no magnet and the parts man said kubota changed that. this morning i took the original filter off and spun on the new filter so i could look at the magnet. the new filter sealed with a very light touch. i cleaned the magnet from the old filter and put it on the new filter causing me to loose a lot more oil than necessary by taking the filter off again. When i spun the new filer with the magnet on it drips fluid with light pressure. i thought the magnet wasn't centered correctly so i took it off again and put it back on and it still drips with light pressure. should i not use the magnet, i don't fell comfortable tightening the filter
