rear axle nut torque

[catbed]

83 850gd

how much should i tighten the rear axle shaft nut? i know the torque required is between 61 and 83 ft-lbs, but i dont have a 24mm 3/8 inch drive socket. i got it pretty tight with the stock tool kit but i know that it isnt at 80ft-lbs yet because i installed a trailer hitch that required 75 ft-lbs and i used a longer wrench than i am using and it doesnt feel like the 75 ft-lbs. <does that make sense? i have know idea.

so my actual question is, how do i determine how much to tighten it(aside from buying a socket and a new torque wrench)? it will be coming off again in the next few weeks i think.

I just tighten it down tight as hell and then line up the hole for the cotter.

Only sensible answer to your problem is to buy the tools you need to work on the bike.
A decent quality torque wrench is needed and of course the sockets.
The rear axle nut is loosened quite a bit for chain adjustments and changing tires. You need the tools. If you under tighten any important hardware and it loosens under use, you can ruin parts or even get in an accident. Over tightening can cause its own problems too.

+1, you pretty much NEED a torque wrench if you own a bike. Even a cheap beam type wrench is way better than nothing. A high quality beam type is the best available and doesn't require regular calibration, but they are $$$. A decent click type is OK as well. Learn to use it properly and use it on everything. If there is a torque spec called out in the manual, I pull out the torque wrench. There is a reason that the OEM is giving you specific torque numbers, use them.

Keith, I would say overtightening is worse than under from what I have seen. And it's REALLY easy to overtighten the smaller fasteners.

.....The rear axle nut is loosened quite a bit for chain adjustments.....

No chain on the 850G to worry about, heehee!
A torque wrench is probably necessary for a lot of vehicle jobs, but you can use my method:
1 finger for under 2 lbs
2 fingers for 2-5
3 fingers for 5-10
4 fingers for up to 30
whole fist and arm for up to 60
all of the above plus 3 foot bar for over 60
:-D
note: use your stronger arm (for me it's the right)
now for the age factor:
if you're over 50, adjust all settings above by adding one finger to each and a 4 ft bar!!!!
over 60, 2 fingers and a 5 ft bar,
over 70 let someone else do the work:shock:

I believe the method Steve told me was tighten it till it strips, and then back off a quarter turn?? LOL

Got me there Lurch. No chain. Still gotta buy some tools though if you want to maintain anything.

And if you don't need it that tight, back off a full half a turn. :-\"
