To add to this this thread:
I had my tools for doing regular usd forks, but of course the ES had to be different for the spring compression. I had read some other threads with some interesting redneck inventions for getting around this. I'm in Canada, so the proper tool is a 2 week wait, leaking for seal now.
I used 2 ratchet straps, one each side. At the bottom I used a brass dowel to anchor through the axle hole (brass just to be careful of the threads, if I didn't have that, any screwdriver would do, just slip a chunk of fuel line over it to protect the threads). At the top, two pieces of paracord tied as loops so the ratchet strap hooks have something to attach to. A simple bowline knot works fine here.
One click a side at a time, slowly crank it down, it won't take much, and you can access the 14mm nut on the shaft.
To release the spring energy safely, pull back the ratchet lever off the lock, hold back the lock from the cam, and ease up on the ratchet, letting the safety engage the next detent. One click at a time, alternating sides. If you're unfamiliar with doing this, just rig up your strap between two solid things in the shop, using a bungee cord to anchor one end. Put it under tension, turn practice releasing the load. I promise, you'll "get it" right away. Then, do it on your fork spring.
