Part of the pdi is checking bolt torque after running the sled up to operational temperature and setting track/belt deflection/check coolant/oil level sensor by tipping on left hand side with low oil while running the sled/hand warmers/gauge functions then sending service report to polaris while machine is running to show everything is operational and then letting sled cool down to stone cold and torque clutch to 80 ft lbs. If all this was done none of this would have happened. Alot of dealers clean the sled set the track fill with oil and fuel and send it out the door not knowing if anything even works. A proper PDI takes time. I've found loose shock bolts a arm bolts suspension bolts primary bolts secondary bolts springs not on exhaust connectors not plugged in faulty oil sensors faulty hand warmers parking brakes that need adjustment to work properly....... Thank the guy that PDI'd your sled and the shop foreman that doesn't enforce a proper inspection. Polaris is a good sled they all have flaws but this was due to poor PDI setup.
I heard the matryxs have had reliability issues right from the start. Even worse then polaris are normally which is scary to think about because its bad to begin with lol
With all the parts supply issues I was wondering if this would start to show up in the build quality. Parts suppliers have a long standing relationship with builders if new suppliers are sourced the necessary steps might be overlooked to maintain the quality the manufacturer usually specs.
I can guarantee you, you will not find a polaris P85 clutch bolt that didn't come from polaris. "Grade" is relative. A bolt that big I'd rather it be grade 5, softer than the crank so it can't screw up the crank threads.
@@leftyeh6495 Sir do you know the Hardness of the Crankshaft ? Did you see any Marks on the Head of the Bolt? There was Zero. So you could use Blue Screw instead of Red. Was you a Machinist? Thanks
This is a difficult application for a high strength bolt. It is next to the engine so gets hot and stretches. It could work itself loose. The 80 ft lb is a moderate tightness. I did not see threadlock on the old one, to my surprise.
Looks like it probably had a crack, or an indication at the cylindrical part of the bolt to the head. And then the stress was to high locally at this position, fatiguing the metal until you only had the "rough spot" left, and then that part just gave up and the head let go.
Same thing happen to me today, second ride I took it on with 5 hours on it, I’ll contact Polaris monday to see what we can do, unfortunately my weekend came to an early end
Remember to carry enough tools to do these type repairs out in the bush. If you break something it is good to at least take the broken part back to town to ensure it matches the new part.
These machines promised 4 stroke reliability but have not proven to be reliable in many cases. For the price all brands should last much much longer than they do
Well, you have the guys that buy new, put on 3-4000 miles in a season and sell them. You have others that are selling 5+ year old sleds with less than 500 miles. They last just fine for the average guy. As quick as they've changed there are very few mountain sleds worth riding that have actually been worn out. Most people think that doing maintenance is hard though, and don't understand we have the closest thing to a factory race motor and it's got a warranty! At least there's no valve adjustments. My 450 manual said to adjust valves every 15 hours, and replace piston every 30 hours under race conditions. When I sold it for another 2t it said to replace the piston every 40 hours....

The clutch is balanced with the rest of the rotating assembly, there are dots on the clutch that must be lined up with a mark on the crank! Looks like you missed that when reinstalling it.
They better step it up. Half of there snowmobile workers are through a contract company and the turnover rate is insane. It’s like a new person in a different station everyday. All they seem to care about is quantity over quality and safety.
They should be sending that broken bolt back to the manufacturer to see why the head sheared off. I have never seen such a clean break on such a high strength bolt.
I like your style. From one Alberta sledder to another! I am now subscribed.
That's a class five Bolt should have never broke or shear off like that especially with a $16,000 snowmobile or more
That's actually a grade 8.8 and I doubt it was loose. once the head popped off all locking tension on the threads was gone and it simply spun out.
@@brokendown63 still should have never popped out and snapped
@@mikeversluis1347 I agree. Looks to me like it was flawed from the get go.
That small rough spot on the broken bolt head was the only thing holding it. Its manufacture defect in that bolt.

Automakers are having the same issue. They are just grabbing at any part they can to get the cars to the sales lot.
Another nice vid! Its not the breakdown but how you deal with it. You guys solved the problem with your brain not your wallet. Great bushcraft.

Polaris junk
What is Polaris building a brand new snowmobiles falling apart that's why I don't buy Polaris I buy Yamahas I got red top triples 2 strokes
That's ridiculous. Got 6k miles on my 19 xrs. Have zero issues yet.

Remember to not buy a polaris. Who TF brings a spare primary clutch bolt with them?
Is our secondary clutch suppose to have play like move back an forth an have a quarter inch of play between bolt and clutch ? Is that normal

How much would it cost to helicopter recover the sled?
Thanks for the videos ... I have the exact same sled and these videos' are great to be in the know with peoples experience on this sled...
Same here better check this before I take my new 22 out in 2 weeks
I wounder if that was a chineseum bolt.

If you read in the manual.. Polaris Clutch's Need to be Serviced ever 1000 miles or inspected. Yamaha Clutches you don't have to touch for 6000 miles.
You’re not much for spelling or grammar, are ya?
He already mentioned there’s only 250 miles on that sled. He wouldn’t have had to service it yet.
Have you guys heard pf a thing called 'Maintenance'?
Definitely have to agree with others in thinking that bolt was poorly made. Casting flaw for sure.
got rid of my 2020xc850. no impressed with polaris
What do you ride instead?
Strange,I swear every Polaris I see with an engine or assembly problem has some kind of purple on it....
Sleds looks so cumbersome. Timbersled is the only way to explore
The clutch is balanced with the rest of the rotating assembly, there are dots on the clutch that must be lined up with a mark on the crank! Looks like you missed that when reinstalling it.
Clutch pieces are balanced as a unit which have markings and is not balanced to the crank.
Well on Rotax motors they have alignment marks, perhaps Polaris don’t. Never worked on one before.

Proceeds to not use a torque wrench 🙄
Your first issue here is buying a Polaris..... ;) Skidoo all the way brother
Good on that dealer
because the bolt was obviously flawed. nice they seen it, and no question. took care of ya. it came loose because of the flaw in the bolt head.
They should be sending that broken bolt back to the manufacturer to see why the head sheared off. I have never seen such a clean break on such a high strength bolt.
My generals clutch fell off. 1000 miles. Castle nut backed off
Your quick drive failed because you got snow in there when you left your side panel open. That one's on you not Polaris.
Obviously the last person who worked on the clutch didn't torque the bolt correctly..
I agree, internet loves going crazy . Just ride‼️🥳
Honestly this is why I have a yamaha nytro
First breakdown was completely due to rider error. Don’t blame Polaris for that one.
I always check everything on my sled before I ride. You got lucky.
No you don’t, no one checks every single bolt on their sled
Second one I’ve see now.
Good ol Polaris
Enough of these cheap parts being used Polaris!!
lol
Junk buy ski doo not America garage
Polaris loves china made bolts...
Buy a real sled
Polaris Quality. What a Joke!
This problem didn’t age well 😂
Tough luck!
