Jinma 354 3 point lift cylinder seal replacement

Here's a procedure I stole from the net. May have been CTOCF. I used this on my FarmPro 2425. It's all done from the rear of the tractor. I don't know if the 354 is similar or not.

There's a picture from the parts book using the reference numbers (XX) that goes with, but I can't get it inserted into the post. Still trying to learn this new format.
