If you don't have a service manual, at a minimum study the parts diagram on one of the online parts dealers, like ronniesmailorder.com. Make sure you're getting everything back together in the right order, and torque to specs. The bolts that hold the springs in get 7.2 ft/lbs, the cover gets 7.2 ft/lbs, and i believe the massive nut in the middle takes 78-82 ft/lbs. I made the mistake of rushing the installation of the clutch on my dr350 last week, and now i gotta tear it apart and do it over because i just hammered the nut on with an impact wrench instead of torquing it to specs like i was supposed to. I think my impact wrench puts it to around 250 ft/lbs, and its supposed to be only 32 ft/lbs on my bike - oops!
But check out the parts diagram, that will give you a great idea of what to expect, and i think i do have a picture of mine torn apart partially so you get an idea of what you will see.
