Lighting is everything.
My sled has 0 miles on it. Only been driven into the garage. Looks as if putting this fix it kit in you pull the shaft a lot further into the chain case. Has there been any issues with that?

Mine looks the same as yours without the insert installed
Well if it‘s two piece it should slide on the shaft. Looking at the comparison photos the fix it kit pulls the chain side shaft further into the chain case.
I guess the two photos are comparing a two piece shaft to a solid shaft.

You are forgetting about the front suspension arm. The driveshaft will not pull in any farther, there is also a shoulder on the splines of the driveshaft.

I’ll watch their install video and get a better understanding of what it is doing.

Yep, the theory of the tki retainer is, it will hold extra tension on that shoulder on the driveshaft spline, the shoulder is what you are seeing sticking out of the insert in the tunnel.
Basically it turns the two piece shaft into a 1 piece.

Well you still have your rear suspension front and rear arms keeping the tunnel together.
Personally I wish Doo would introduce proper drivers to fix ratcheting problems. Current ones are soft cheap black plastic which will start to fail after you first time get ratcheting. So keep your track tight from the beginning but not too tight.
Driver you could do something crazy and try a set of aftermarket drivers 
powder freaks make a real good one I’ve run them on my 21 and used to install them on 175 with BD sidekick turbo builds . Avid too but I have no reviews on them never tried them

I keep saying it but I rode with 4 G5 turbos last year and we all just followed the Doo manual tightening spec and we didn’t have one failure. Luck? Maybe I don’t know but I do know on my 24 Turbo I am going to keep doing the same thing I have done since I started riding sleds and it is to follow manufacturers spec.
Buying parts and bolting them on cause of an issue I have never experienced cause some guy tells me I need it who is profiting off forum discussions doesn’t interest me. I know BRP engineers have more time and money backing their research than some dude coming up with a “fix”.

Haha engineers can only test so much in a lab and handing out a few demo sleds to professional riders is only going to tell you so much in a few seasons before releasing to the public.
Put those sleds in the hands of the public who aren’t professional riders and let them bash into trees, land throttle pinned, pin and wiggle to the dirt or in a creek bed, trail racers doing 65mph with 3” paddles that will be your durability test. I would say last year doo engineers deserve a pat on the back for only coming up with what a few issues a fuel hose and some chaincase parts. Let’s see how the 24’s do with the upgraded parts before we pass judgement. I have no problems eating my words if I am wrong [emoji23]

"Haha engineers can only test so much in a lab and handing out a few demo sleds to professional riders is only going to tell you so much in a few seasons before releasing to the public." exactly and this statement supports the idea of probs arising, like this potential one.
"Buying parts and bolting them on cause of an issue I have never experienced..." is faulty logic. plenty of faulty products get released and whether or not a given person has experienced any issues is irrelevant. it's the overall stats that count. i have no idea how many '23 summits were sold but assuming 5000 (which is prolly low) and you've been around 4 sleds with no problems. that's making a judgement on the remaining 4996 sleds based on the circumstances of 4 or .08% of the total. nowhere near enough data.

How is anyone here basing chaincase failure rates? From what they have seen or heard of same as me. I haven’t seen or heard BRP releasing those numbers to the public probably never will.
Yet we have products being made and sold to us cause of what’s being said on the forums or what they see being brought into shops. Forums are notorious for people bringing up problems or issues very few posts bragging about how someone has had no chaincase failures.
Obviously at the end of the day it was a bigger issue cause they issued a fix for the 23’s. I will buy into what BRP is selling me over what a backyard mechanic designs in his garage.

you're basing your opinion on 4 sleds out of thousands. that's not how stats work. there are plenty of chaincase failures. pics are all over the web and the fact that doo is replacing parts is proof.
could be strictly due to the parts doo is switching out but the fact remains that there were at least two changes made that could cause a failure. the wobble is a valid reason and until that is proven otherwise, it remains a viable cause.
do you know tom's credentials? dude could be an ivy league educated engineer. you should give him a call and talk to him. he's told me some interesting things about this whole situation that are surprising. he works with BRP in some capacity which is pretty good for a "backyard mechanic in his garage".
buy into whatever them lawyers that dictate policy at BRP tell you.

I am basing my opinion based off of what I experienced last year. I rode 50 days last year not once did I come across a chaincase failure nor did I talk with anyone who experienced one. The only ones I heard about failing was the people here on this forum. Stats also don’t work off of pics you saw all over the web…
I feel the fix the team of engineers BRP put out for the 24’s is proof they feel the problem was the manufacture of the gears and chain not the driveshaft wobble. Actually they put the “wobbly” driveshaft in even more of their sleds this year further proving they feel the issue was in the gears and chain. They obviously stand behind their driveshaft and I have no reason not to believe them.
I don’t know Tom I’m sure he is a great guy and he obviously has a desire to take an engineered product and make his mark on it. I think it’s great he is trying to help people out and make some
money off of it at the same time. Can’t fault a guy for trying to put food on his table.
I told you I buy into and form an opinion on what I have experienced and other around me not Internet forums or pics all over the web…

To each his own. Your sled do what you want.I didn’t have a problem either but it’s didn’t stop me from improving on the design and eliminating a bad one. TKI is a cheaper route to the one piece drive shaft. Food for thought, why did doo install a solid bottom sprocket in the 2024, when the lighter one with the holes worked for years without a problem. The next two months will tell the tale, I say the issue is mostly corrected, I still don’t like the thought of a tiny aluminum rod holding the tunnel from spreading, maybe that got updated for 2024 and its a thicker rod?
I also updated the crappy plastic rear suspension insert to an aluminum one, I didn’t have a problem personally, but I know guys who have broken them, are they aluminum for 2024?

Yeah I asked this local aftermarket company make me ones for last season. Tougher material, higher/wider profile, did work good last season.
