Yes we use the seal for an Allison AT540 #23010610, it is a little smaller inside diameter and will seal on a rough shaft better tha the one for a pts 2500. We used a pipe nipple that would fit over the shaft and ground one end down to a sharp bevel and retapped the ground down end to get some threads on the end and put a coupler on the other end with a cap in it and drilled and tapped the cap for a threadded bolt or all thread with a nut welded to it to remove the seal. A piece of black pipe made a good installer.
