Trying to rebuild one of the main lift cyl. on my "64 Ford 4000 loader(Wagner-Superior). It is a single acting WELDED cylinder. I got the packing nut off the end and the stack-up of packings out. BUT, I cannot get the snap ring out of the bore. It"s about 2" down and does not have any way to pry one of the ends down/out. The ends are square cut and no other notches anywhere else. The end nut compresses the packings against this snap ring and gland that it holds in place. I tried to push this gland back but it won"t budge. Which makes sense because the packings are compressing against this and so there has to be a shoulder there that won"t allow it to move any further in. Also, the way this ring is in there it is somewhat captured by this gland. Is this a non-serviceable unit? HELP!!
