So the manual says to torque the rear axle to 48-52 ft/lbs of torque. Since we know the manual is wrong on the proper torque value for the oil plug, I'm nervous this may also be wrong.

Don't want to prematurely wear out my rear bearings by over tightening.

Any thoughts?

Froggy, your belt's on the wrong side!!!

Mnviking, this isn't a plug in an aluminum housing. You're tightening the inner races to the spacer and they need to stay put. As long as the spacer is good then you're okay, no worries about side loading the bearings then.

Read it again. You torque it twice with a loosing in between. And 50 works for me too. Oh, and, my belt is on the "right" side.

I knew about the torquing it up to 38 ft/lbs then backing out 2 turns then retorquing up to 48-52 ft/lbs. Just didn't want to overdo it. I am a Viking after all and we have a habit of put a little too much into it.

It's not 38 ft-lbs; it's 24-26 ft-lbs then back of two full turns. Then 48-52 Ft-lbs.

If one was on the road, without a torque wrench, how would you go about getting the torque setting right? If you counted how many turns when you loosened it and divided by 2,for the halfway point, I guess that would get you in the ballpark until you got access to a torque wrench. Did I answer my own question?

No, I'd use a different approach...

You know how much you way, so figure the proportion of your weight that the torque value is, and go that proportion of one foot out the wrench, and put all your weight on it.

So if you weigh 100 pounds, you would go 6 inches away from the center of the axle, and put all your weight on it (100/2 = 50, 12" / 2 = 6).

If you weigh 200 pounds, put all your weight 3 inches out (200 / 4 = 50, 12" / 4 = 3").

So for this application, if you weigh about 200, put all your weight about 3" away from the axle center.

Or go light, and torque it again when you get back to a torque wrench. With those pinch bolts, it's not going anywhere.

Or swing by the nearest auto parts store... I bet they have one they would loan you.

I remember it the easy way. 25 pounds -2 turns then 50 pounds. 50 foot pounds is just 50 pounds of force applied one foot out on the handle of the wrench.
I had a torque wrench I didn't trust. So, I would pick up a 50 pound weight till I had a feel for it, then applied that much force on the wrench a foot out.
