Check your hydraulic screen/filter

[clemsonfor]

I went to change my fluid. It's not been 500 hours but that would take me forever to get that many hours on it. It's been quite a few years since I changed it. Full change maybe 12? I did partial changes I believe or either drain and refills when I did axle work I believe. But this thing works hard in the 90 to 100f summer hear bushhogging and it was cheap fluid so I decided to change it. Actually been on my list for years now but we know how that is. Anyway pulled the filter and it has several tears in it. Wasn't really dirty, some debris on it but not bad. But the main seam was coming apart in a place or two and several other spots it had a few years. I know when I initially hot this tractor it had all kinds of crap on it when I did a fluid change. I rinsed it clean with diesel and reinstalled it. I DO NOT remember these tears then. I noticed them first thing as I pulled the filter out so I don't know why I wouldn't have noticed them going in when I reassembled it last time.

So if I was you and it was an original and it is something you been meaning to do I might do it sooner than later. Apparently that brass or stainless mesh, whatever it is, has a finite life on it and I surpassed mine.

I will get some pics today when I get home to post....no I'm not patching it just getting another from Hoye!

My old screen looked VN. for sure. But who ever did it has done a few no doubt about that. Replaced the screen IMO. Esp. comparing it to the new one. It was bent up and a crease right in the middle so I replaced it. 800+Hrs. Since I changed it. First of this year I was only showing 1/16 on the Stick so went ahead and picked up 5gal from TS. and topped it off. Pin hole leak on the Axle. It's so pitiful and knowing it does it after parking it. I'm going to change it at 1000. Never use the 3Pt. lift much. Rear scoop a few times and my mower every now and then. I had trouble getting all the water and sludge from the pan. New Fred. filter and all's been fine. 13yrs to get that many hrs..

I tend to check it 1X per year. Just got to have 3X CLEAN 5-gallon buckets to grab the J20C fluid. Then check out the filter, clean and re-use. My machine came with the newer generation of re-usable filters, stainless main sleeve with holes with an olefin mesh over the cylinder. I have a lengthy write up over on the TractorForum site in the Yanmar section with many pixs.

Yea that's what mine is. Reusable and cleanable mesh.

I will add, my fluid was awfully dark. I caught some in a cut apart clear water bottle like I do with many fluids I want to look at as they come out. The bucket is a dirty used oil bucket so dipping put of it is not a true representation of the oil. I caught some mid stream after I pulled the plug.

I'm inside today so just checked my Serv. manual which I'm looking at the Hyd. Sys.. No Serv. recommendation but use "John Deere Type 303" and Check and refill on the stick. In a rice patty I can see what the sludge came from which was Water. Mine White and milky no debris when I changed it. The filter was just in bad shape which is just the metal screen Cyl. Type. After 3 decades I'm sure all the break in wear is pretty much gone and just straight forward geared Trans.. Powershift is whole different setup!! Sealed clutch so forget that debris. I'm not even all that worried at a 1000 hrs. serv.

Yep.

I wrote a little story about it.

Yikes , Luckily mine wasn't that bad!!! Oh forgot a picture. It's been raining and bad thunderstorms since I got home. I'll try to go out here in a bit.

After seeing that thread assured me pretty much they just redone the Screen. The bead on the screen was huge and looked to be brass or copper. The replacement one looked the same as in the Pic. just new. I could have cleaned it but since I was headed that way to Fredrick's anyways and just another reason to replace it. Cost of it was minimal.

You did good. As I recall I paid around $60 to replace the mangled screen in the photo.

The good news is a couple of years ago when I opened up the transmission to replace the right axle housing, the fluid was so clean (after several years) that I just wiped the sump clean with rags, filtered the fluid with almost nothing found, then re-used it. For a Powershift I would get new fluid but for this simple gear tractor, YM240, which doesn't get many hours per year, that seemed sufficient.
