[QUOTE="Jyuma1, post: 122131, member: 22244"] Well, Murphy strikes again. I can't find a gland seal kit for my backhoe. The cylinder has a number stamped on it... CTD C30 138A but that number cross references to nothing. I'm guessing I'll need to eyeball the original seal but I don't know how critical the sizing is. I removed one of the seals and by some miracle it came out fully intact but it's hard to get an exact dimension as the seal isn't exactly round. I know the ID is 1.5" because that's the size of the rod. I also know the grove the seal sits in is between .325 to .330 (hard to believe 5 thousands of an inch would make much difference). The only other dimension would be the OD of the seal and there's where I run into a big question mark. I have no problem measuring the OD by placing the seal on the rod (makes it round) but I would expect that the seal is compressed after all these years of sitting inside the gland nut. It measures 1.887 but that's likely smaller than what a new seal should be. What to do? :unsure: [/QUOTE]
