Well I have an air impact wrench, but I dont wana use it to retighten a variator nut because I dont want to over-torque it. Well I had a bright idea, use a leather belt as a strap wrench to hold the variator, and use a torque wrench to tighten it perfectly to spec no guess work. I assume this will work to get it off as well, probably easiest with a friend and a long breaker bar. Im gona test it once I get my new variator. Hopefully the belt can hold it securely enough, plenty of ppl use em for filters etc. It would definitely work with a strap wrench with a solid handle though. woot, im really leery of overdoing it with an air wrench since I worked in a car shop and saw so many cars come in that had a previous mechanic overtighten lug nuts with an air wrench and just ruin snit.

30-40 ft/lbs on the 50cc's, around 60 ft/lbs on the linhai 250cc types. Not sure on the 150's. Your milage may vary. Mine from factory was extremely hard to remove, so I'm guessing it was around 120 or whatever the max on the assembly line was.. That is not unusual.
I made a cheap tool by measuring the distance between the holes in the variator, and using a piece of flat bar aluminum that we had at the shop. I notched out the area to access the variator nut with an extension on my torque wrench, and drilled holes so that I could run a couple of 3" long bolts through the flat bar. Using nuts on either side of the bolts let me set the depth to accommodate the height of the socket. The flat bar is long enough that the end braces against the ground.
