</font><font color="blue" class="small">( Hi, I own a JD 4400 tractor, with a 420 frt end loader. One of the bucket tilt cylinders is leaking badly. My question is, how do I take this cylinder apart? I know that the end cap (Hydraulic cylinder rod guide), has to come off first, but there in an internal snap ring holding it in place. I can't find a way to get to this snap ring, let alone compress it. Any help will be appreciated. Thanks )</font>
I rebuilt the cylinders on my 410 loader, and had this same problem so I went and talked to the mechanic at my dealer.
When you buy the rebiuld(seal) kit from JDParts, in the package there is a orange piece of plastic, like a ring. You put that ring in the groove of the cylinder body where the snap ring is. Then you pull the piston out (or you can hook up compressed air to help) The plastic ring lets the snap ring slide past the groove.
I got one in each rebuild kit, but only used 2 of them to rebiuld all 4 of my cylinders
Clear as mud?
Hope this helps...
