I thought id post this and may help others...my oil seal leaked on the xt660r. So i had to change it..so ill speed through this so as you get the idea. the prob is getting that darn hex bolt out the bottom of the leg to separate.
ok, lets speed up...fork out, top off, spring out, oil drained....
now we are left with this ****** to get off...


so like me..u dont have tools, you dont have a rattle gun, and there is no real way to get it off. when you turn it, the inside cylinder turns....so i remember reading a post and gave me this idea...
take one of these...


standard timber rake i had..you can use a timber handle of some kind....and you take the bottom off and whittle it away like this...
