BW4481 NR3 transfer case overhaul info requested

[oldchev]

I have a 2004 Denali AWD (NR3) BW8881 transfer case. I am doing the overhaul with bearings and seals plus a new HV076 chain. It really only needs the front seal but while its out …
Without spending $200 for the overhaul manual I am wondering if anyone out there has one.
GMPT04TURM is the supplement.
Anyway … I would like the torque specs for the case halves (torx head srews).
I was thinking 18 ft lbs? Most everything else seems obvious (to me) unless someone has some precautionary warning you would like to share.

Well excuse my spell checker … Its a BW 4481 not a BW 8881.

Regardless, anyone have the torque specs?

Ok guys (and gals) and others that want to know ...
Borg Warner 4481 transfer case bolts (actually a Torx screw) for the case halves is 15 Foot Pounds.
On final assembly clean mating surface of case halves thoroughly and dry. Use the proper anaerobic sealer and circle each bolt hole one side only. An accelerator can be used at this time.
Previously be sure to have cleaned blind threaded holes with brake cleaner and dry with air, then use a drop or two of blue Loctite on each bolt and torque to spec noted above using an even staggered pattern to snug evenly.
