There is a few steps there. Here are a couple pointers without me thinking too hard, I just put an Ice Ripper XT on my 2007 F6. Not necessarily in this order.
1) remove rear skid bolts, loosen rear idler wheels, leave front skid bolts in and pull out skid, it slides out off the hanger bar in front, that's why you don't have to loosen the front skid bolts.
2) Take all your extensions , snap them together, go in from the brake side of the drive shaft with a 16 or 17 mm socket and break the bolt loose NOW while everything is together.
3) Loosen drive shaft nut by brake caliper & rotor , soak 1st is helpful.
4) remove secondary & belt, remove ( ONLY ) the bolts that hold the Diamond Drive to the bulkhead/tunnel. You can pull the diamond drive without opening the case or removing the fluid....IF YOU WANT , I would tear that down afterwards & Clean, inspect.
5) Unplug your reverse switch, and all sensors, at connectors, another connector is on the brake side , can't remember the name.
This is a pi$$ poor set of directions if I must say so.... but will get you started. If you have issues just post back, and I will explain my poor directions or PM me. I have a 07 AC service manual on disc that I could copy and send to you . Kind of making up for the mess above.
I generally only get the manual out when I get stuck.
