    Not sure on the 208 but the 205 is 250-300 or so ft lbs. That nut doesn't preload a bearing, it only holds the yoke on.

    Since it's likely a prevailing torque style nut you might need a new nut.

    well im not buying a new nut, im having another 208 being rebuilt (free /forums/images/graemlins/woot.gif) and just need it to stay on till then.

    what is a prevailing torque style nut? /forums/images/graemlins/thinking.gif

    i know it was a motha to get it off, but i though i got it tight enough the first time. the second time i just tightened it up so it wasn't loose and it stayed like that for 2 weeks. /forums/images/graemlins/thinking.gif

    A prevailing style lock nut is commonly used in high temperature and critical applications like a pinion nut, or as you found, a front output nut.

    It can't be repeatedly reused (that's why it was a bitch to get off). It is designed to be installed and stay where you put it so it doesn't come loose.
