Bad luck mate. You shouldn't really have to be doing all this work if other road users kept their eyes open and wits about them!

There are only a couple stages in fork disassembly that tend to give you a headache:
The first is undoing the damper rod bolt on the bottom of the fork leg. Sometimes they just come undone easily, other times the rod spins inside the fork leg and prevents you undoing the bolt. If you have access to a compressor and rattle gun, it’s easy. If not, you can compress the fork (caps and spring removed) and invert it placing a length on wooden dowel in the fork tube and resting that on the floor. If you press everything down as you undo the bolt, the added pressure on the top of the damper rod generally stops it spinning. There is a “special” tool to hold the damper rod in place, but I’ve taken my forks apart three times now and never needed one.
The second challenge is removing the top bush and oil seal from the fork leg in order to separate the fork. You can remove the top bush on the fork leg by using the fork tube as a slide hammer as the bottom bush on the fork tube won’t fit through the bush on the fork leg. Just push the tube down and pull it up until it hit the top bush with some force. Repeat this a couple of times and the bush will work its way off.
Assembly is the reverse. It’s easy to refit the bush in the fork leg (after fitting the damper rod, tube etc.) with a drift. Don’t worry this time about the damper rod spinning when you tighten the bottom bolt. Just get it on the best you can to ensure everything is seated right and then, when you’ve refitted the springs and caps, the tension will hold the rod in place and you’ll be able to tighten it easily.
Good luck. Hope you get back on the road soon...
