I am preparing to pull my transfer case and do at least a partial rebuild. My Ford repair manual indicates the rear output flange nut requires a torque of around 260 ft lbs. Is that correct or a typo? That seems to be very high. I don' have a torque wrench that goes that high.
It also states that the nut and washer are to be replaced. Apparently it is self locking and can only be used once.

I would believe it and accept it, and from what I've read, you will need to build a bar to hold the flange and use a super long breaker bar or a great impact driver!

I didn't ask for your life story, just answer the question!
260 lb-ft seems about right. I alway use an impact to remove and reinstall them. I've never replaced the nut or washer, just a little blue locktite.

Sounds about right to me too. I wouldn't bother replacing the nut either.

In theory, theory and practice are the same. In practice, they are different.
That’s in the same range as the torque for the pinion nut on an 8.8 differential. Similar application. I believe it

×3 on a little blue Loctite.

They tell you to use a new nut because it is self-locking. But if you put something to lock it, then it's fine to reuse it. Just be sure to clean the threads of any oil before you reinstall it.

How much do you weigh?

260 FOOT/pounds, is 130 TWO foot/pounds

So with a wrench with a 1 foot handle you need to apply 260 pounds of pressure at the end of the handle
2 foot handle 130 pounds of pressure
3 foot handle 86 pounds of pressure

I had thought about using Loctite. Thanks for confirming that is an acceptable approach. If I can't find a proper torque wrench, I will use a 3 ft breaker bar and apply an estimated 87 lbs of force. Again, thanks for confirming the 250 ft-lbs is appropriate.

With an 8:1 gear reduction a good running 2.9L might be able to create enough torque to tighten it. :icon_rofl:

(I'm really trying to move up on this "list".)
