Oil filter on JD-B

Joe, you could have a problem there. That oil filter stud runs up through the oil filter body [#3] & attaches [threads into] the oil filter head cover [#8]. ~The other thing that sometimes happens on those old 2-cylinder Deere's is the filter body [#3] starts to crush & bend if the cover nut [17] is overtightened.
~If your problem is a broken filter head or bent body top it is quite a job to repair. It's not too bad if the crankshaft is out but is a real pain if you have to work around the crankshaft.
~The first thing to do is MAKE SURE you don't have 2 gaskets [14] under the bottom cover [15] as that will cause you a big problem. ~To get the filter head off you will have to pull the filter outlet [#7] down, an old 5 gallon pail handle works good if it is bent a little so it will hook in the holes in the side outlet holes. Once hooked in the holes a hammer of piece of pipe can be slammed down in the handle to pull the filter outlet down & out.
~Probably the place to start is to identify where your problem is then post back with it's location & we can guide you through the repair...
