8mm Allen wrench and some muscle. Non-drive side. Crank arm will self-extract.

but on the non drive side there is a 8mm hex screw and then this hex plate on top of it. i tried turning the 8mm and it loosens up but it seams to be blocked by the hex shaped plate on to of it. do you understand or know what i am talking about?

Yes I do! That hex plate is your self-extractor. When the 8mm bolt bottoms out on it, it will pull the cranks of the taper of the splines for you. They went this route a long tine ago so you didn't have to have an extracting tool.

so i just keep turning the 8mm and the hex plate is there to extract the cranks?

You got it. piece of cake. And it will give you resistance as your pulling it off, that's normal. It doesn't hurt to check that hex to make sure it's not loose, either with your fingers or a 14mm allen. Who the F%$%^ has a 14mm allen wrench though. You can use a fractional bolt head in lieu of a 14mm. Can't remember what size off the top of my head...I think a 3/4 or something close. You get the picture.

No worries. No dry F#%^ing....use liberal amounts of grease when reassembling, including the splines. It will keep things nice and creak free.
