I am trying to set the preload on the output shaft bearings
on my 3-speed transfer case. The Toyota Factory Manual
says that the preload should be between 10 and 13 pounds
and the Haynes manual say between 2.6 and 9.0 pounds for
"new bearings".

The factory spec for the J30 case is 2.6 to 9.9 pounds of pull with a cord wrapped around the parking brake drum. This is not foot pounds because the radius of the drum is considerably less than 1 foot. Used bearings should be more than 1 pound, but presumably less than 9.9.

Thanks PH. Perhaps part of the confusion comes from the
fact that the factory service manual shows the fish scale
pulling on one of the parking brake studs (less lever arm)
and not on a string wrapped around the drum. My factory
manual is very old, was printed in Japan, and is full of
what we used to call Japlish.

BTW, did you ever see the photo of the dog teeth
wear that I posted?
