ok the top cylinders I thought were going to be a pain but turned out to be one of the easiest to due
1 loosen up the collar first with a pipe wrench or the correct spanner wrench if you can find one,
2 then loosen up the key that holds the pin in place, you only need to take the one out by the cab the other one is to hard to deal with,
3 loosen the hoses and take off
4 knock the pin out you don't have to knock all the way thur just enough to get the cylinder out, now finish taking off the head or that collar slide it back and take a photo of it there is one
plastic ring in there with a oring, 99% of the time these do not need to be changed out but you just got check most likely their fine due to know one has changed them anyway
5 pull the cylinder to the front of tractor then raise up to clear the brace or rops depending on your unit.
6 now a lot of oil is going to come out once you start pulling the cylinder up so be ready get a large old hose and slide over and have it going to a bucket or some other catch device.
7 once you got cylinder clear you will see the outer orings and seals on the back head those should be fine unless their torn up or scored really bad then you have to change em out
8 the front head the inner seal is easy to get out with a pick, the front seal towards the front of the head is metal and its a pain, I took a pair of dykes and cut a good 1/4 of the top part of the
seal out then use a small flathead screw driver or chisel but be careful the head is aluminum and scores easily. before that there is a metal keeper on top a pick can get it out after a few minutes of prying then start on the metal seal
9 once you get it out then clean real good break cleaner or your favorite stuff. the inner seal is easy to pop in the flat side goes in first the crown of the seal will be facing your , the metal seal
that one I used a 1 1/2 in socket and fliped it over and placed on top of the seal, flat side down the crown will be up, put socket over and grease it up and tap it in, then put in metal ring or keeper and that's it.
10 put a fair amount of grease on the rod and outer heads and seals, put back on road and tighten nut up I forgot to mention that should be around step 8 or so.
11. even though you got oil in the cylinder still put some grease in there so the seals will pick it up plus the it will hold the O rings in place once you start tighting up the head to the cylinder
12 that last o right could give you problems once there is only 2 or 3 thread left and the oring put some more grease there so you don't compress the oring it needs to slide under the cylinder as you tighten it and that's it
