Thank you very much Kubmech, I'll sleep better tonight knowing I'm not tearing up my tractor. Best wishes for the holidays.

I know I am late to this thread, but I have to also add my thanks to kubmech as well. I noticed these same disconcerting developments on my B2910's 402 FEL (after about 20 to 30 hours of use), and I was sure I had overly abused something. Whew, am I relieved!

New development - I noticed after looking closely on the garage floor that there is a very moderate leak around the right hydraulic ram for the dump action. It probably leaked a 6 inch spot in about 2-3 days. I wiped off the cylinder end so that it was dry, and used it. After putting it away again, it was still dry (about 2 days of weekend use) so it didn't seem to leak under pressue during that period. Now that it has been sitting again (for about a week), there is a spot again and the cylinder end is wet again. Why does it only seem to leak when it sits, and not when its under pressure? I would think if there was a leaky seal, it would leak more under pressure. I have a mail order machine, and I don't really want to test the waters now for warranty work if I don't have to. Any ideas?

Paul, it sounds like what you have is a gland seal leak. Many times this seal will leak static but not with sytem pressure, due to the "umbrella" design of the seal it seals better under pressure than when sitting static. I would'nt worry about warranty due to mail order. The loader should be covered for one year from date of purchase. Kubota will have a record of your warranty date and any dealer should have access to that information. Take the cylinder off and take it to your local dealer with model and serial number of the loader and tractor. It should be covered as long as there's no nicks in the rod.
Oh yeah, one more thing, on a few 2710's or was it 2910's I don't remember. We had a problem with bucket cylinder bracket alignment, which caused preload of the bucket cylinder. If your machine has this alignment problem it will cause premature failure of the cylinder gland, gland seal and possibly the rod. When you pull the pin on the bucket side of the cylinder take note if it's preloaded or not. Most likely angled to the left as viewed from the front of the machine.
Kubmech,
Thanks for your diagnosis. Its been a while since I posted my problem (end of Nov.), but I'm glad I waited (procrastinated)/w3tcompact/icons/blush.gif before I finally got around to taking the cylinders to the dealer. Sometime over the winter I noticed that the left one stopped leaking and the right started leaking, but the lack of pressure was still there. When the bucket was on the floor, I could step in it and rock it just with my light body size/w3tcompact/icons/wink.gif. I finally tok both cyclinders to the dealer, and he fixed me right up. Thanks to Kubmech, I told him I thought it was the gland seals, and he agreed. He replaced them, but Kubota needed him to send the defective seals back, since they believe they had a "bad batch" of cylinders a while back. Apparently there is a groove for the actual gland seal to sit in, and the inner diameter of the seal was a larger diameter than this groove. What that means is the seal never actually touched the cyclinder ram, but was just "hiding' in that groove. I suggest that the rest of you that have noticed any similar problems check with your dealer regarding the "bad batch" of cylinders and thier gland seals.
On another note, this was my first visit to my local dealer for warranty work. Since I didn't buy it there, I was a little nervous about how I would be treated. After providing evidence that I did, in fact own the tractor, where I bought it, etc. They treated me like royalty. Said to be sure to call him up if there was ever anything else he could do for me. Great!!/w3tcompact/icons/grin.gif CaseKub3 - Pete, if your reading, 2 things - Register on TBN, and tell Bob once again what a pleasure it is doing business with him.
