My buddy is replacing the clutch plates on his DT400 and he's stuck at the torquing down part. His books says to torque the clutch bolt down to 55 ft/lbs. The schematics refer to the six bolts in the pic as clutch bolts, but the torque specifications says clutch bolt (singular). My google-fu found a tute for replacing the clutch plates on a DT400, but he didn't torque anything down nor did his clutch basket have the center adjuster nut. Anyone know anything about this clutch setup?
