Good info dave.
Dave, do these turbos have the hyvo gear and chain in them?
Owner’s manual says there will be a decal on the chaincase, but my sled does not. I don’t feel like taking the chaincase apart to look.
I find it odd all of the reports to check the chain because of stretching that wasn’t a comment I recall with the G4 turbo. Thinking of it, I do not hear the whine of the hyvo on vids I watched so far like I did on the G4.
Was the decal a miss on my sled, or are other sleds missing the hyvo warning sticker.

No for more gear availability is why.
Pay more get less seams to be the norm now days . I’ve already replaced my chain and gears with hyvo ones from a local supplier. Was going to run belt drive but don’t want to loose foot room on right side . 300 miles chain was stretched a lot .

That’s very interesting.
Do you mind taking a pic of the P/n of the gears that came out of your sled?
They are in the scrap metal bin out front of my shop lol I had no plans on ever using them again I’ll try and dig them out

That is not a HYVO gear part number, that’s for a NA sled. Hyvo is 4188.

If your chain has a LB stamped on the side, that’s not a hyvo chain.
I just confirmed on my sled, It’s definitely not a hyvo gear or chain.
This is a big mixup and it already created a issue at the dealer, the parts Fiche shows HYVO gears and chain’s because they have a customer looking for a chain.
This is a hyvo chain with the 3910 non hyvo gear. It does not fit.

Top pic is the Chain on my 2023 turbo. The bottom is out of my T3. Same chain
Dave is correct, my sled does not have hyvo in it. At this point, I will not assume all 2023 turbo sleds have hyvo or not.
Now the problem That’s already happening as proven in this post, is now guys are now changing parts thinking everything is the same as before. Parts Fiche says the same p/n for the gears and chain since the turbo was released, but I confirmed today that the fiche is not showing the same parts that are installed on my sled, and will be a problem at the dealer parts department level if a customer is looking to replace a chain.

Yes if you put an older chain or a N/A Chain on a 20.5-22 turbo it will wear really fast. You must look up parts for your model year and sled, as there are differences. 2023 the chain and gears is the same across all summits N/a or turbo. There is other stuff as well so if your running a lynx then make sure you check lynx parts do not assume ever all parts are the same. So checking with your dealer is paramount, cheers dave

If using a normal chain it will wear extremely fast.

i will check my chain and probably put the stock gear back in. i don't want to screw something up. thanks
nothing wrong with updating things but you want to make sure you use the right stuff, i learned a lot from engineers, like many guy think oh just make this or that stronger but then it can cause more damage as just building something up strong means it can pass the load to somewhere else, an easy explination of this is putting lots of bracing in the e or s module and guys think that is better, it can be for certain hits but then it also can pass a big hit to somewhere else like the tunnel, its why you see more damage in tunnels on polaris vrs s or e module on doo, just food for thought when you go and spend money on things and think your doing something high value when the stock parts are fine and will be fine under normal use of the vehicle, cheers dave
