Yep, that would certainly cause a leak.
Glad you got it fixed.

Glad you have it fixed. I learned the hard way to. I repaired one cylinder and then the next cylinder I took it to a hydraulics place and it ended up $20 cheaper to have them do it as compared to me buying the seal kit and doing it myself.

I just took a cylinder from my LA463 to a local shop 1 hour and $128.75 later I took it home... Very reputable shop and quality work... I used them before on a John Deere loader and it was a little cheaper because it was not metric...

Same here. I'm a DIY'er, but I farm that job out.

too far from a shop and enjoyed doing it seeing it was so simple.
These Kubota hydraulic cylinder seal kits are expensive. The most pressing problem seems to be the rod seal, the one with the metal ring and the rubber seal nested inside. Trying to find a direct seal distributor where I can just by that seal. Has these markings: " WPS 1.250 1.690 0.187" which I assume are the dimensions but no clue what the WPS is. Also it has this number P01112 and the letters TCS. TCS is the manufacturer maybe? Gone to a couple seal distributor websites and they don't have anything with these measurements... any help would be appreciated.

Just an educated guess, but the rod seal you describe is probably the outer wiper seal. That's probably what WPS means. If it's actually leaking oil from the rod the inner pressure seal is leaking and you'll have to take it apart to get at it.

I bought my last seal kit on ebay for my 1991 JD round baler.
On the difficulty of the job, I found 2 problems: finding the locking mechanism for the shaft portion and getting the packing to go back in the hole when finished.
If the locking mechanism is an externally visible snap ring, or it's obviously a screwed on cap, it's easy. Cleaning of paint and foreign material from the inside diameter of the cylinder helps in piston retraction. If the locking mechanism isn't visible externally, depress the piston and look on the inner side of the cylinder just below the open end....like ｼ" below the end, for an internal snap ring. Pop that out and the piston should come out.
My biggest problem getting it back together was the cylinders on a JD 152 loader...100 hp tractor. Took some imagination but got her done. Small cylinders no biggie.
Obviously the cylinder is usually removed from the tractor and both fittings on the cylinder are open.....can't pull the piston out of the cylinder if the lower fitting is plugged.

TCS is the manufacturer in Taiwan, Cheng Mao, Precision Sealing Co.
PO1112 is the part number (letter "O" not zero)
WPS (I think you meant WPB) is the wiper style, cross-section and material (nitrile)
The cylinder is in inches (not metric)
1.250 is the shaft dia
1.690 (1-11/16 I know 1.687") is the OD of the seal or ID of the pocket in gland nut face
0.187 is the depth of the pocket in the gland nut face.
To search the web for a replacement, try 12501687 and 12501690 then look for the 187 depth
www_tcsoilseal_com will get you the oem catalog (replace the _ with .)
been there, done that... for the next guy
