BW 1354 transfer case rear output flange nut torqued, but still has play

[traildog]

So I found the torque for the output flange at ~160 ft-lb and was able to tighten it just to that before the engine started turning. I'm still feeling a good bit of axial play on the flange- I'm assuming it is meaning the output bearing isn't properly preloaded. My 1/2" dewalt pneumatic impact wrench tops out right around 120-150 ft-lb so I don't have an easy way to continue tightening.

Get a better impact wrench? Put a breaker bar on the crankshaft for something to tighten against with the torque wrench?

Would appreciate any advice, thanks

So after a little bit of anguish and research i realized the output bearing is a radial deep groove bearing, not an angular contact pinion bearing like a differential. there's no crush sleeve or the like, so the bearing probably does not need preload. I'm going to leave it as is with a small amount of axial play. Any confirmation of this conclusion would be appreciated!

Been a while since I've been inside one of these transfer cases but I do believe you are right that it is a regular ball bearing as opposed to a conical roller bearing. Thus... no preload.
