My first JD tractor ever so know little about them. It's a 1938 unstyled A. Changed the oil and then thought I would pull the bottom round plate off at the bottom to maybe flush some sludge out. Took the smaller plate off and out drops a gear and long shaft with a gear on the end. Not a good sign when parts start dropping out! Then tried to remove the larger round plate with the screen but seems very tight and can only work it out about an inch.
Shouldn't this screen assembly pull right out? Gave up and pushed it back in and then put the rod and other gear back in, turned the engine over some and watched but the long shaft gear is not turning. Must not be connecting up on top with what ever is suppose to turn it. Is there another part that may have fallen out inside, or that dropped off the top of the long shaft??? Please Help! Thank you in advance for any info on this.

On later A's, there are two oil lines that are attached to the top of the oil pump, and those have to be disconnected before the pump will come out. If that's the case with your model, and you have to go in from the top, you'll need a small light, long arms, and short wrenches. Good luck.

Why-Me, well congratulations you have just opened "Pandora's Box"...The pump body won't come out because there are oil lines attached to it inside the crankcase, you will get a look at that soon as you are going to have to pull the crankcase cover to re-install the square coupling that connects the oil pump gear (long shaft) to the drive gear at the cam. The little square coupling will probably be found in the bottom of the crankcase. Post with more questions when you get the cover off.
