First thing is to loosen top cap and bottom bolt while the fork is still on your bike, otherwise you will have to find some way of clamping it like an old yoke Image
Then with the fork off the bike you can undo the top cap and with a pair of 17mm spanners or socket, ensuring you use a ring spanner or socket for the top, slacken the nut a little to allow the top cap to be removed
Image
Remove a large washer (2") the spacer tube, another washer and the spring cleaning fork oil off as you go, then tip out fork oil into a container
Then remove the bottom bolt you loosened earlier taking note of the copper washer which may still be in the bolt recess but needs to be kept with the bolt.
Now the cartridge comes out.

Carefully prise off the dust seal and pick out the wire clip holding the seal in
Image
Now you have to use the fork like a slide hammer to pull the fork seal out, note the holes at the stanchion bottom have sharp edges which have now cut the old seal. You might like to attack these with a round file and emery cloth, if you do be sure to clean all traces of swarf and abrasive grit.Image
With the seal comes a washer and outer bush,on the fork leg is the lower bush, check these for wear and replace as necessary.
Now you can remove the bottom bump stop and its spacer, these will be covered in the thickest and dirtiest oil so clean them and in the bottom of the fork, white spirit works well

Excellent "how to". Very succinct. If you follow it, make sure you read every word carefully!
The bold is a particularly good tip:-
"First thing is to loosen top cap and bottom bolt while the fork is still on your bike"

Not just because the fork is nicely clamped, as mentioned, but also because while the top cap is still on, the spring is pressing on the damper rod and helping stop it turn with the bottom bolt.
Very frustrating when that happens because the "official" way to stop the damper rod turning involves a special tool.
