My son asked me, when he had the wheels off of his '22 850 Ultimate Trail Sportsman to mount up a set of new CAMSO tracks, what the torque values should be on the hub bearing nuts as he was adding some grease to his hub bearings - and off the top of my head (DUH) I told him 110ft/lbs. for some reason thinking that was what I recalled reading at some point.
Now, it hit me last night - and got me wondering where I got that number from..
I have gone back this AM to see if I was right or wrong and have noted some references to it possibly being 80ft/lbs. instead!
I assume proper torque values are there for good reason and having 110 instead of 80 (if that is what it truly should be) would make a real difference and now the tracks (and hub nuts) should come off and get retorqued properly (big job.. which I should do - considering the poor information I passed along)..
But before I go through all of this - are the torque values for the axle hub nuts, front and rear, for a '22 850 Ultimate Trail 850 actually 80ft/lbs.?
Thanks for any input - he hasn't driven it very far so far - which is probably a good thing all considered - so if the nuts are too tight I would assume (you know how that works) nothing should have been screwed up so far..
Thanks - Randy

I'd assume it's better then 30 ftlbs to loose.

Guess my question is (and I pretty sure I know the answer already) what should the torque value actually be - and how much difference does it make all things considered?

I have a 450 ('18 - HO EPS model) and I did those nuts at 70 front and 110 rear - now I'm not sure if those are correct either - I've seen numbers all over the map from 70 square through to 80 square to 70 f and 110 r - which I presently have them set to as I mentioned.. There should be a chart or sticky made up for this site so the real and actual numbers for many, if not most current and past models, can be easily seen by and for idiots like me that don't apparently have much of a clue!

Ask latebird for a manual for your year machine. Typically stuff like that doesn’t change from year to year, but you never know. The torque value for a 2018 850/1000 castle nut is 80 ft-lbs (108 Nm) per the service manual.

Thanks - pretty good 'Brain Fart' is this on my behalf!
Guess I had the 110 value stuck in my cranium from doing my own rear ones lastly!
I will be taking everything apart as I have messaged my son a while ago, to correct it, which with the tracks on will be a fair amount of work all things considered - but how badly (if at all) can this much of a difference make, if left as - is, and if so how quickly?
Any thoughts?

Accelerated bearing wear comes to mind for one.

Accelerated bearing wear comes to mind for one.

All fixed up - spent a good portion of the afternoon on the cold garage floor amongst puddles of water dripping off of the tracks and all - but got it all back to the 80ft/lbs. it should be.
We just installed the tracks a couple of days ago and they needed some additional tweaking and adjustments anyway - so while we were reinstalling them that all too took place as well!
Pretty cool out today here -20 degrees - so I'm gonna park inside and try and get rid of the chills - this getting old is for the birds - I used to love this sort of weather and could play outside all day in it - even in light clothing and without a garage at all.. but now I prefer to just look through the windows and snap open a 'cold one' instead!
Thanks everyone for the comments and assistance - my own bearings and tracks will probably get attended to in a few days once the weather hits a bit of a warmer spell and I do know they are 70 and 110 ft/lbs. as per the Polaris specs, although the rears do seem like a lot..

I'll go along with that!

What model is that for?

What model is that for?

Must be 450/570 models..

 

[crazyflyboy30]

I have a Sportsman XP 1000 and has the same bearings and 80 ft lb of torque is what the book has but go to 100 with no problem because I know any slack can cause wear and even have the hub to break.

The question was:

The answer is;

Polaris 450/570 from the latest version of the Service Manual Latebird sent me, I believe it's 2017 - 2019 but specs haven't changed for later models.

Just to be clear, OP was talking about a 850 Ultimate which the specs are 80 ft.lbs. You provide the specs for a 450/570 which are 70 front, 110 rear. Now we know.

Original poster also said "I have a 450 ('18 - HO EPS model) and I did those nuts at 70 front and 110 rear - now I'm not sure if those are correct either." I was responding to that.

The correct answer is setting 3 on my light duty Milwaukee 18v impact for 450/570 and 850/1000

I believe my manual called for 100ft/lbs.

I have been running 80ft/lbs on both my alloys and camso tracks.

I strongly suggest being careful to tighten them evenly and in stages.

Good advice on the torque procedure.
This is how I said to tighten lug nut if you don't want to break them.
