Adjusting the Chain on the 2023 Gen 5 Ski-Doo Summit Sleds

[caper11]

no, I’m not sure how that works. if I do so, it seems the dealer would want the sled to prevent riding and further damage. if that’s the case, i’m not losing any riding days because of the dealer or a busted chain case if I can prevent it and what I’ve spent on parts is negligible.

The parts In The fiche are the correct sprockets and chain, what’s in your sled is not. Just saying.

you mean that would be significant if i bring it in for service in terms of not having what it came with?

Are you referring to the driveshaft insert?

Referring to draining the chain case oil and taking a look inside to see if there is excessive wear where the TKI kit is then needed. Seems like most of these pics of this issue are guys with the turbo, wondering if it is as bad with the guys that have the NA 850.

Claims need to be put in to correct a problem.

My sled will have HYVO, and Im also doing the 2022 driveshaft.

 

[jcjc1]

understood. i'm just not willing to lose any sledding days which is what i expect would happen with backordered parts, etc. so i'll see what's going on after the season.
i thought about using the 22 driveshaft but figured i'd try the TKI solution. after installing it and seeing how it works plus how stout the parts are, i should be good.

For those that are having failure or whatever. What pre symptoms are you having.... besides loose chain on every ride. Are You having vibration noise or.......

 

[jcjc1]

i never heard or felt anything and tightened my chain when i got the sled home to do my own PDI on it and checked it thereafter. the wear although very slight, had already started with hardly any time on the sled by the time i opened the chain case.

Just checked my lynx and chain is stil tight. 172 miles

The lynx turbo has a different chain, that is just as strong or stronger than the Borg Warner stuff.

did the lynx sleds also get the driveshaft coupler?

Great video, a guy in another forum said he had to do 30 turns, pretty much proves thats BS

"You can’t just keep cranking the chain tight there’s a limit to the chains ability to stretch if you tightened it more than 4 times it’s at its limits"

This is false!

oh sorry Dave thanks for clearing this up for us as usual great information I was clearly wrong. So nice you finally come back here and took all our fears away cheers

i put 250 hard miles on mine. day 2 i turned it about 4 turns and 4 days later it has about 1/2" play in the clutch so it probably needs a couple more turns

Hi - Figured I'd add in more real world examples to show that this is not an isolated event/ just 'forum rumors'. Although, I will say that the gen 5 turbo is a SWEET sled and the power/ride feel is awesome! But this weekend after chatting amongst a few of my immediate buddies, I can report:

1. My buddies' 23' turbor chain blew up at 330 miles, stranded him in the Whistler backcountry and had to leave sled overnight. (No pics yet)
2. I saw the issue and took apart my own chain case today on my 23 turbo r to find slight wear on the inside chain case. I'm at 200 miles
   • View attachment 399509
3. My second buddy also took his 23' turbo r chain case apart to install the TKI solution today and had much more wear on the inside of his chain case, at 350 miles
   • View attachment 399510View attachment 399512
4. We (along with 2 other 23' turbo r users who have not taken apart their cases) have all experienced the 'abnormal amount of tensioning' we need to do for our chains after each ride

Upon our chatter, I spent hours digging into this, between reading forums like this, facebook, and other outlets, it appears there are some common theories:

1. The issue could be the two piece design on the drive axle, solved with TKI's solution: https://tkicnc.com/product/g5-chain-case-retainer-w-speed-sensor/
2. As stated very early in this thread, the parts received (53 tooth sprocket, 21 tooth sprocket, and chain) do not line up with what the parts finder online says.
   1. According to the parts finder,
      1. The 53 tooth sprocket should be: 504153997
      2. The 21 tooth sprocket should be: 504153910
      3. The chain should be: 504153397
   2. What I actually have on my sled:
      1. 53 tooth sprocket: 504153998
         • View attachment 399506
      2. 21 tooth sprocket: 504153910
         • View attachment 399507
      3. Chain (mine also reads 'LB537' as caper11 called out on page 1. Although the part # is not stamped on it (or I could be blind..probably the latter)
         • View attachment 399508

So my question would be, we can eliminate the slop TKI identified with the TKI solution, but if we do indeed have the non-HYVO spec sprockets/chains, do we replace with the items listed on the skidoo fiche? Or do we skip that, and go to something third party like the this: https://www.hotrodsledshop.com/skhygechkitf.html ? Ultimately, for me, the goal is to have piece of mind that my chain is not a ticking time failure that will happen while I'm out in the backcountry leaving my sled stranded and me two-upping back home...

Just curious, would that kind of wear on the inside of the chaincase push you to replace the inside case half? Or would you run it as is?

I’ve asked this question before since Dave is knowledgeable on the chain
What is the service limit on the chain ? I’m getting conflicted information from you and the service department from some dealers I talked to .
Can you please confirm that it doesn’t matter how many times you tighten it as long as it’s tight ,
When to change chain . when one side is touching the other side? Asking for a friend . Thanks for your help .

Confirmed on 23 DS4100. I did the TKI fix on mine last night.

Where I worked we dealt with roller chains all the time. We ran with a hard 3% stretch rule. It’s a very general rule other factors included what the pins looked like and what it was operating. Measuring under tension is key to it.

I realize your probably being facetious with your question since you been very vocal about all the failures you have heard about and changing your entire drive system but regardless I will answer with what I know

3% is what information I was given from numerous industrial mechanics . Also researched with dealers they told me after the first stretch of the chain you have a 4-5 time adjustment and chain should be replaced. I don’t make this stuff up in my head I actually do some research . Maybe I’m getting the wrong information from dealers and individual mechanics?

Thanks frankthetank for your information on the chain stretch ?

It’s all good man you and Caper brought us this info of chain failures mis matched parts very early on when none of us where even thinking about it I appreciate it.

The 4-5 turns rule is very plausible it sounds like an old mechanic from his days has learned that anymore than that the chain needs to be replaced.
