the P drive has proven to be a pretty good clutch. Maybe thats an optioon
I would honestly take either option over what they have going on.
I half wonder if they ran loctite and a lower torque amount on the clutch bolt.
If that might help the issues. Or a bigger thread in the crank and a larger bolt?

I haven’t first hand seen the carnage or the cause.

Less torque and some red Loctite is a good idea. Pretty sure someone’s tried that. I’m assuming they’ve tried it all since 2022 🤷‍♂️

Carrying a spare bolt isn’t going to help much.
They are generally breaking, not falling out. You would need all the tools to extract the broken piece (if even possible) and the crank and clutch would have to be in useable condition. If they were just falling out, you could simply put it back in.
Also, there is a shortage of the bolts. Buddy in my vid said was waiting for one from the dealer when it broke.
Rumour is that the titanium ones aren’t trustworthy either.

I was referring to carrying a drill, easy outs and all the tools that they went back to truck for. Also the tititiam bolt would be lighter, titanium is only on par with steel in terms of strength, it does so at half the weight, which makes it one of the strongest metals per unit mass. Has anyone thought of trying a grade 9 bolt which has a tensile strength of 180,000PSI or is this already 8.8.

More info i Found that maybe the Polaris garage mechanics/engineers could read.

  1. Grade 8.8 bolts: Also known as structural grade bolts, they are typically made of steel and plated with several coatings.
  2. Grade 10.9 bolts: As these bolts are most often used in the automotive industry, they are also referred to as ‘car bolts’. They are made of boron or carbon steel and have high tensile strength (1040 MPa).
  3. Grade 12.9 bolts: Known for their strength, these bolts are most often used in the manufacturing and construction industries to join medium or heavy industrial parts such as an automotive engine.
  4. Grade 14.9 bolts: It's simple: these are the most durable bolts you can use in your application. Perfect to join large structural elements to each other, the grade 14.9 bolt has a whopping maximum tensile strength of 1400 MPa.

You could have a grade 9000 bolt with 1,000,000,000,000PSI tensile strength. It would still fail.

I work for a manufacturer of large scale equipment with high vibration. We use 8.8 and torque to a lower value than industry standard on our installations. We have found higher strength bolts actually break more frequently.
Not saying it’s apples to apples, but “stronger” isn’t necessarily better.
There’s definitely something unique going on. The load on that bolt has been engineered and it’s of similar size as every other modern sled out there. It’s not rocket appliances.
Harmonics? Clutch slipping and tightening the bolt? I think we’re past a qc problem of the bolt.
Buddy thinks it’s the loose outer sheave.
The bolts are also custom to this application. You can’t just get a higher grade one from a supplier.

The 1987-88 Indy 400’s had bolt breaking issues,something funky with harmonic for that displacement.I think they used aluminum sleeve over bolt with O rings,I don’t recall other models having issues.

Harmonics for sure. I agree with that. Guess there’s a vibration going on

If memory is correct older Polaris clutch bolt was 7/16”NF grade 5.

Look at alot of the content creators on youtube alot of them have some
Pretty nice toys so there has to be money there, also,muskoka buys used trucks and his last truck he had alota kms on it all depends where he decides to put his money. Some youtube guys and the stuff they have baffles me like bruce wilson if anyone has see his stuff 2 brand new semis no cdl/1a and hes not even a trucker

He even said in his video he had a crappy house. And you can tell from his videos it’s nothing special. Has pre owned trucks and his gf has a basic car.

It costs him 10g for fuel/food and accommodations for a season. This next part is purely an assumption. As he is a legit business all that cost is soaked up through his business. While as most construction guys do in Ontario . He either banks his OT hours for winter or he goes on unemployment. And the sleds may be either purchase through his business or bought personally and maybe sold later to the business as they are tools and equipment.

He’s even talking about not buying a new sled this year because of how much he will loose and how the sleds he has now, do not have any real kms on them this season so they should be good for another one.
