The part number for the replacement friction disc is SC42FPK and cost about $90 shipped, depending on location, thats directly from Spec.
The little bolts and nuts holding the friction plate should be torqued to 6-7 ft/lbs per Spec's help desk.
Thought Id post this info up so it can be found later if anyone searches. I looked all over the net and couldn't find the torque specs for the friction plate.
