John Deere 'B' oil filter stud

I have never replaced one on a B but have twice done so on A's. On A's it can be accomplished from above through the crank case cover but it is not a particularly easy reach even for a lefty which certainly helps! Most guys pull the filter assembly out of the main case & reinstall it with a replaced casting.

Take your filter cap back off, remove the filter & you'll likely see that you're able to wobble the stud all over the place inside the open chamber. Maybe even able to push it up into the crank case some until it hits something else. If so, I suggest you consult a manual like an IT if not a Deere manual. They give pretty good instructions on how to R & R the filter assembly.

Good luck.

I've only worked on a "D", but from the I&T manual (# JD-4 page 21) the filter assemblies look similar.
I would check to make sure that the 'nut' that threads onto the stud under the filter bottom cup turns easily and that the stud isn't bottoming out in that nut before it's pulled the the bottom cup up tight against the gasket! Mine was very crudded up and the stud bound in the nut. Make sure that the end plate and the filter outlet assembly are actually there. Both of these pieces were missing in mine and oil was by-passing the filter!

Good Luck!
