My brother picked up a cylinder for a splitter that is in need of seals, with shop air there is blowby extending or retracting the cylinder and it is bubbling around the outside of the gland. It has a threaded center "nut" that appears to pack the rod seal and 4 bolts that appear to hold a outer shield on (it sits loose once you pull the 4 bolts off) I am assuming that it needs a "spanner" to attach to the bolts and keep the gland from rotating, then to remove the "nut", slide the outer shield, then see what needs to come out next. Some pictures: The bolts and the "nut": Trying to look under the shield: Aaron Z
More pictures: Numbers cast into the base: And the piece welded to the cylinder that the hard lines are welded into: Overall view: Anyone know what it may have come off of?
