John Deere 4320 - Clean suction screen HELP!

[gbw]

Hello,

I'm changing trans fluid on my 2006 e-Hydro Deere 4320, but I cannot remove the 'elbow' between the transmission and the pipe to the oil filter. (400 hrs, it doesn't get a lot of use but I enjoy it.)

Deere book says to remove this elbow to get at the suction screen for cleaning.

I removed the 2x 12mm cap screws, but I cannot get the elbow loose. It looks like the pipe between the elbow and the large trans. oil filter is swaged on, both ends, and I cannot get it loose.

I tried tapping the elbow with a wood mallet and it loosens but does not come free, it looks like a collar or somthing extends beyond the elbow transmission side flange and into the trans. Book shows only an O-ring.

Does anyone know how to safely remove this elbow?

THANKS!!

Did you or does anyone have a trick for removing the elbow? I am having the same problem on a 4720 doing its first hydraulic oil change. Everything is really tight and I have tapped with a rubber mallet as hard as I could and still could not get it to move more than about 1/8" . SHould I take the filter back off? Is there something holding the pipe in the oil filter that I am missing? In the manual it made it seem like it would just slide right out. Not the case at all...Anyone who has done this job please comment...I am in the middle of my driveway and can't move the tractor until I fill it back up with fluid.

Ok, I pounded it until I got it out, but not without a little damage. I pinched the O ring with a screwdriver and it is now broken. Anyone have any idea of what size O ring this is? I was hoping I could get one at the local auto parts store this afternoon.
Thanks

Hi, I know this is an old thread but if you're still here, I could sure use some help. I also have a 4720 and cannot get at the screen. I removed the two bolts of the L bracket but pipe and bracket barely move. Did you pound the L off the end of the pipe or did you remove the pipe from the filter assembly area? Any help would be so appreciated.

You can get a box of different size o-rings at harbor
freigh approx $12 or less
You should have a parts list showing where all the
parts are to get a better idea of what yer lookin at

I have the O-ring, I'm looking for guidance on how to remove the L Bracket to remove the screen.

Will this work??

It's a press fit which can be loosened and freed. Adter a number of years, it's stuck...use a small oil filter wrench to turn the tube back and forth and just carefully work it loose until you can remove the pipe. The only thing holding the pieces in place arw the 2 bolts which you aleeady removed.

Hi Willy, thank you! That makes sense as the tractor is 12 years old but only 230 hours on it so the "stuck" part makes sense. Once loosened, should I expect to remove the "L" piece from the pipe first, then remove the pipe from the oil filter assy? Or do I leave the pipe in the oil filter assembly and just pull the screen after L is removed? If I get this done, I'm going to send you a gift card as I've called numerous Deere dealers and none know how to do it. I so appreciate the guidance.

Is there a rubber hose on the elbow that holds in the suction screen? Mine has a rubber hose that I can slide up out of the way if I loosen the hose clamps but it can be difficult. It sounds like yours is different than mine?
