You can just pull this vent out of the valve assembly with a little twisting motion and out it comes. Mine was plugged solid with dirt and grease. Blew it out and popped it right back in. Roll

Final report, refresh of Hydraulic 3-point All back together, works fine. After 6 days leaving the arms in the fully raised position, they dropped 3/4 of an inch, maybe slightly more. I can live with that. Before the repair they would drop to full down overnight. Good deal. Now on to the...

Re: Interim report on 3-point hydraulic refresh Here you are. The acid test. No leaks, no alarming noises, just a smooth ride up and down. I'll have to wait overnight to see if it still drops. I don't know how to set up a video so I'll just give you this link. https://youtu.be/ZZkSjvPtFqQ...

Re: Interim report on 3-point hydraulic refresh Thanks Dave and TD, going out now to torque it down and start working on the linkage. Will start it up and work the air out before I put the seat and it's hardware back in so I can see if there are leaks. Roll

Re: Interim report on 3-point hydraulic refresh Replacing the valve/piston assembly went fairly well until I realized the bonehead move I had made... Laid out the 1/4 in bead of Permatex over the groove on the differential side. I had already cleaned the head assembly side, so we were ready to...

Re: Interim report on 3-point hydraulic refresh Thanks Wolf, I'll follow their directions.

Re: Interim report on 3-point hydraulic refresh In the picture below you can see the narrow groove cut in the facing edge of the lower case. I expect this is to let a small amount of gasket material to fill that groove and help seal the valve assembly casting with the differential case. I...

Re: Interim report on 3-point hydraulic refresh Sorry, beyond my ability. All I can tell you is that if the arms are going up the piston must be down in the cylinder. It is normally pushed down by hydraulic pressure. The bang you hear may be the piston arm hitting a safety plate that rides on...

Re: Interim report on 3-point hydraulic refresh This has to make you (anyone reading but especially Dave) smile. I went fishing in the bottom of my differential case and caught a fish! LOL The pictures tell it all. The pic of the end of the magnet is right after pulling this collection out...

Re: Interim report on 3-point hydraulic refresh Ah well... It's the defect in my DNA. It's just not right. It's needs to be repaired and I am retired (have the time). There is a limit however, I won't spend the extra money for a new casting or even a new control valve but I will invest the...

Re: Interim report on 3-point hydraulic refresh Got it Dave, O-ring on top side, retainer ring on bottom side of slot. All the parts I bought are Kubota including the O-rings, bolts, snap rings, even clips. Thanks, Roll

Re: Interim report on 3-point hydraulic refresh Huh! Never occurred to me. At first I thought that had to be wrong then it gelled. With the rounded edge facing away from the direction of force, force could actually cause the snap ring to spread and ultimately fall off. That's really...

Re: Interim report on 3-point hydraulic refresh Thanks Wolfman, I have checked and to replace the valve is expensive. About $400 as I recall. I'll just reinstall as is. ... except for one puzzling thing. The diagram shows a snap clip on the parts drawing. It is missing on my valve. I have...

Not exactly on point with your question but thought I would add this... I bought a B7300 without a mid mount mower thinking I would add it later. It did have a FEL. The mower would work with the FEL, I knew that from some research and the fact that the example I purchased had originally come...

Re: Interim report on 3-point hydraulic refresh Most or the marks I can see but not feel. There are a couple that I can detect with my nail but they do not seem to be deep. I had some drop while using the tractor (I think) but my concern was that the tiller and later, the two lower arms...
