One way to remove the lift all is to replace the 4 3/8 inch bolts that hold it in one at a time with threaded rod. Put nuts on the rods and then thread it down, being careful not to unscrew the rods out of the clutch housing. First though, you need to drain the lift all of oil and remove the elbows (they unscrew) for the hydraulic connections and remove the operating lever. Also I think you have to remove the oil fill cap. There is a "cross" coupling that drives the lift all. It fits in slots in the drive and driven coupling pieces that are on the transmission shaft and the lift all shaft. One of the "crosses" has to be vertical in order to lower the lift all. The seals run on the coupler pieces that screw onto the transmission counter shaft and onto the lift all. Unscrew those pieces and then you can remove the seal holder/bearing retainer and replace the seals. Lock the countershaft to unscrew the thing by putting the PTO in gear and holding it from turning. I use an old PTO universal joint yoke piece for that. You jam something in the gears of the lift all pump to hold it from turning. These things can be difficult if jammed on tight. I had to dissasemble my lift all and build a jig to hold the and keep the shaft from turning. I was afraid a metal object (like a screwdriver) jammed in the gears would damage them. While you have the lift all out, it's a good time to redo the clutch if it needs it(another longer story), or at least inspect it.
