I put in a very heavy urathane U cup seal that will definitely not blow out even at thousands of psi. I modified the original seals in my machine when I rebuilt the adjusters. So I doubt if hooking up a 2500 psi hydraulic source is going to hurt anything but it also may not help anything either. Just doing the math it should put out 2000 psi or more.

I don't know what mine puts out but it is a standard full size gun with about a foot long handle. I even found some high pressure ones that are supposed to put out 15,000 psi. I did some checking, a common long handled grease gun is supposed to put out 3000 to 5000 psi depending on the gun. I just put fresh in a couple of years ago and when I bleed the adjuster on the opposite side the grease comes out nice and smooth. I did manage to get the track back on with the help of heavy forcible equipment and when I inserted grease back in the housing to try to readjust the cylinder it never moved but grease oozed out the bottom through the casting. So what to do now I guess would be to install another housing if I can ever get the old one off. My guess is it did not fit properly when changed but worked for awhile then seized. Further inspection of the cylinder housing revealed that the housing was previously changed and that it must have come from an earlier model as it only had one hole in the casting where the nipple went in.there was no other relief screw on it as the parts diag for the 350B showed. John Deere 5220 Utility Tractor is equipped with a John Deere 3029D diesel 3. I removed the grease nipple and used the bucket on the loader to try and push the adjuster back toward the spring.very little grease did come out and it only went back about an inch and then sprung forward a 1/2 inch when I released the bucket.
