BTW Rob do you happen to know the torque of the bolts for the rear of the transfer case that houses the seal and the gear drive for the speedo?
i am still searching for manuals for this...? thanks! Casey

30 pounds. Here is a link to repair/rebuild of the case. Since yours is not being rebuilt, and likely has reasonable wear, do not bother with the shim adjustments.

Well finally had some time to crawl under and put the rear back on the transfer case. and yes a bolt got easy to turn when torquing,"Why do we keep turning knowing it's gonna break" It did so there was enough to grab it with the Vise grip and get it out then start over with new bolts. I didn't think 30 pounds was that much but it did snap so was weak anyway. Now that the skid plate is off I may as well move to the fron end and do that pinion and front output for the transfer case as well.
If you read this Rob are the seals the same for the front Diff as it was for the rear... a 5778? and the front output the same seal as the rear output? I hope to be able to re assmeble it sooner than later... Thanks for the good advice Casey

You can get away with about 24 pounds torque, just to be safe. A lot of the problem could be the cheap torque wrenches we buy.....many are not properly calibrated, and if they were when new, that calibration can wander over the years.
Front pinion seal is the same as the back pinion seal, and the transfer case front output is also the same as the transfer case back one.

Awsome thanks Rob may get to it this weekend!
yes I know what you mean about the wrenches...Ha Princess auto all the way! I got some new bolts from work. the old ones were a grade 5 new ones are an 8 but will take it easy on the torquing!

Well finally going to get to it...maybe today. weather is nice and sunny too so...
have to ask rob torquing the four bolts for the seal/speedo gear housing 30 lbs or 25 to be safe...should I put anything on the shim pack...to seal it on the block or housing itself before bolting it on? Also the torque of the companion flnge that holds the brake drum...it was not that tight to begine with so tighten it up as before or torque to the same as the yoke...175 ft lbs? Hope you are doing well and the 6x is keeping you busy! Casey

Go to 25. Grade 8 should handle 30, but why push your luck. 26 is the low end for the grade 8 I believe, so you should be OK there too.
Yoke should be very tight, so 175. It only tightens up the compnents on the shaft, and does not effect the bearing preload. That is controlled by the shims, and you are working with worn bearings anyway. We usually held the flange with a holding tool, because getting the proper torque didn't work as the engine would simply turn over. The reason the nut was loose was likely that the last guy installed it with a weak impact gun, or hand tools that were inadequate.
