Here's how I do the lower 2 seals. Remove forks. Chock the wheels so the machine can't roll. Lift the carriage so it is about 8' high. This exposes the 2 lower chrome shafts. Take a 2' length of 4X4 and place it inside the outer channel so that it will support the center channel. Take a 4' length of 4X4 and place it inside the center channel so it will support the inner most channel. Lower the carriage until the channels hit the the 4X4 supports. Now chain the carriage to the mast which will be about at 6' high. If you want to prevent a massive oil spill you can remove the bleeder plug on the top of the cylinder and push the lever to down position. You can strap the lever with a bungee and give it a few minutes. That will allow a lot of the oil to drain back to the tank before disassembly. Remove the four 1/4" head 12 point bolts that hold the manifold on the very bottom. They are recessed up in there so you need a socket. Remove the two 3/8" bolts and nuts on the sides of D that hold cylinder in place. Lift the small chrome shaft and remove the snap ring and the 3 keys that hold that lower foot on. Remove the snap ring under part C that holds it to the cylinder. Remove the eight 12 point bolts that hold C on and remove part C. Now it's ready for the seals. The small one is easy because the gland nut the holds it is threaded on the outside of the shaft so it will go in without any threads rubbing it. The bigger one is like the ones on top where you have to use or fabricate an installation tool to prevent damaging the seal. Note that gravity will want to make the shafts drop so be aware. It is handy to have someone help you hold the shafts up as you remove the foot, C, old seals, new seals. After it is all done bleed the air out of the cylinder up top at the bleeder and walk out saying to yourself "that's the last one of them I'm doing"!!
