Chain case life Gen 5

[F_ast]

Does anyone know if there have been any chain case failures with Tom's fix?

It will be interesting to see if the 24' still have a failure issue this season.

I'm on the fence about purchasing the kit with the dollars I've put out this year.. but it is a justifiable expense I suppose

I believe TKI has a new video out. Sounds like there is still issues even after the updates

I have seen pictures of the shafts that have not been seated properly, resulting boring in the tip of the split shaft to fail. This is an installation issue. Make sure that your shaft is always seated properly. If you look into the tunnel and you can see the rubber seal (black O-ring) the shaft isn't deep enough inside the chain case mount.

Not a concern of mine, two piece shaft is no longer installed in my sled.
I am also not sure how it’s possible to not have the spline not fully seated and assembly the drive shaft properly.
Now I have seen a broken front suspension aluminum rod, that made the tunnel flex and the driveshaft came out of the sleeve in the chaincase and failed the chain, chaincase, etc.
That aluminum rod is the only thing now keeping the tunnel from flexing, how many of the rods are broke and not reported on the internet analysis?

tunnel flex is something that i've seen some chatter about in regards to it being an issue with doo's new design. the driveshaft prior to '23 acted somewhat like a stabilizing brace between the left and right sides of the tunnel i.e, joining them together. the tki kit restores that but if tunnel flex is an actual problem or contributing factor to chain case probs, who knows?
i wondered the same about a fully seated driveshaft in terms of how could that be and still work properly. seems like there's have to be a lot of lateral slop on the brake side for it to move in that direction.

new tki vid:

as ultrasaurus stated, tom mentions ongoing chain case probs with '24 sleds but he didn't elaborate.

"There has been problems on ´24..."

Like what problems? Why won't he tell us exactly? He is making a claim that nobody can confirm or deny, leave people hanging and end the video. Go get that bag while you still can and run haha

If you ever spend 2-3 day getting your sled out of a spot just so the heli can get to it you will understand that not all aftermarket stuff is useless. When you live 10 hours from mountains you want to eliminate all risks of failure you can .

It almost sounds like they're breaking the end of the driveshaft off - but maybe I'm reading into it too much.

i'm all for being skeptical but i give this guy the benefit of the doubt after speaking with him. i suppose we'll see as the season progresses.

Snake oil if ya ask me. What proof is there there was a problem with driveshaft causing gear failures? I think brp updated gears and chains cause that was the issue.

 

[firstkitty]

I seen a guy get a helicopter ride out last spring with a 23 his front arm broke and the shaft pulled out of the socket enough to strip the splines . Wish my phone wasn’t dead I would have took a picture of that hot mess he would have bin able to ride out if he would have had the tki or solid shaft .

 

[Ultrasauras]

So is this fully seated? Does anyone have a pic like this with the insert installed?

that’s how mine looks.

 

[jcjc1]

so the question is, is there the same wobble in the 24’s? if so, they have faith in the design and if not then we know it was an issue.

Not snake oil, it’s good preventative maintenance.
The sprocket and chain release is a back pedal answer to a supply chain issue, with possible knock off parts.
Look at the design differences 2022, to 2023. What’s holding the bottom shaft insert in the chain case, what forces can cause a part to move and fail? Whats holding the tunnel from spreading apart? What force is put on the driveshaft when the track is tensioned. If you have personally seen how much slop was in the 2023 splines, you would not say the tki is snake oil, but a cheaper solution to a solid shaft.


How many have heard the grinding noise on the trail at slow speeds thinking it’s the paddles rubbing something, but there is no rubbing? New noise for 2023 over the previous year sleds.

I’m not trying to sell parts for tki . I don’t actually care if guys want to run it or not . First picture is a sled with 2 part shaft with tki retainer. 2nd is with solid shaft conversion . This imo is the solution to all doubts with the hyvo upgrade. Only my opinion.

 

[High Voltage]

I had a chain case explode once years ago, and remember the hassle of getting it out. I ordered one up, it is a pretty cheap peace of mind.

 

[Blu Du]

i dont think it takes a rocket scientist to look at the play in that shaft and say that shaft doesnt have a long life

 

[High Voltage]

Hell mine looks even worse.

Not sure what you are referring to but that driveshaft stub looks different to me.
