I never had any issues last year. I just installed the tiki for insurance
Chain case life Gen 5
- Thread starter snow-doo

This guy should put the driveshaft and coupler back to sled and see if there is wobble then. Bearing will keep the coupler in its place and it is solid construction when drive shaft is properly seated and bottom gear is secured with circlip. Ofc theres little play otherwise, it normal you cant make fitment too tight.
On other video he also sells his own oil for the chain case. Most likely its just atf on expensive bottle.
If the driveshaft was in the sled and installed like it should be and it had no wobble then there would be no need for a product to fix the wobble and this video and his product would be a moot point…

Cat used this same design from 2004 to 2011 with there diamond drives it was a good idea be because they tied the two together with a bolt through the shaft center to prevent it from moving. Brp has a good thing it just needs to be refined.
Beating a dead horse driver if people want to put it in. If not don’t. Kind of like a clamp on Polaris driveshaft. Tom is an avid sledder and outdoor enthusiast. I highly doubt he is dependent on selling this kit.

This is being beat to death for nothing, same as on another forum. If guys don’t want to install something to make the shaft stronger, then don’t.
As someone mentioned already, this needs refinement and I totally agree. If doo really wanted a quick change track, then a one piece drive shaft and a belt drive would have been my vote. That two piece shaft see’s two opposing forces on it to rely on a sloppy dry fit spline. When something is spinning at a fast speed, a thousand of a inch of misalignment makes a big deal in reliability.

Yeah its hard to prove something that doesn't exist.
If you open the chain case and measure this "wobble" when bottom gear is on, there is probably less play than on the crankshaft. If you take your clutch off and measure play on the end of your cranck, I promise you will be surprised how much there is. And that thing is spinning +8000rpm.

Agreed, I would have been more convinced if he demonstrated with the driveshaft in the sled installed in the sled like it comes off the showroom floor. BRP engineers designed it like that for a reason. It’s good people are questioning BRP’s standards and as such TKI’s should also be scrutinized.
For you tired of this dead horse it’s a forum it’s a place to discuss these topics. If you’re sick of a topic don’t click on it…

I look at it this way. The places we drop into and you’d never be able to pull a sled out. It’s pretty cheap insurance, even if it’s just for my mind. I also add a skid plate. If it really needed one, BRP would’ve installed it, right?
Manufacturers doing stupid things. Just look at all the Stupid, what were they thinking things with Poo the last couple of yrs. Its mind blowing. currently hyfax is pealing off the 24s due to no end cap on the rails and the hyfax is getting hit/caught on the windows of the track. they are all capable of stupid S@#T in the name of saving wait. I dont think the slop between the gear and the shaft is a good thing either and would most definety run the TKI fix
It’s everyone’s choice to customize their sled to their liking . If you want to run it do so if not don’t bother. I personally dont want the 2 piece shaft it has no purpose on my sled if I swap my track I’m going in the chain case regardless to service and inspect components. I also think some people don’t like to be wrong in an argument. When it’s your own sled it’s not wrong if your satisfied.
Skid plates, stronger bumpers etc. are accesories. Drive shaft isn't optional, you kinda need it.
Accessories are a good money for the factory and also they want to keep dry weight as low as possible for marketing reasons.
My problem with TKI is that they make claims that are not true and studied. They just took the shaft off and say "oh there is play here" and refuse to see the whole picture.
Ofc, everybody can do whatever they want for their sleds, nobody here has said that you should not or you could not.
But we are discussing the topic, not about who is wrong and who is right.
Is it wrong to question things? I mean, all these companies, BRP, TKI are in for the money. Their aim is to make money. We should never forget that.
I agree we’ll over 90% of stuff is snake oil and for a majority of riders the sled is fine out of the box , i still believe the old solid shaft that was proven for 15 years is what the sleds should have
.if so I believe this topic would never bin started .
Also remember the tki is advertised as a fix kit kinda like the Polaris 800 cfi (fix) kit peps bought millions of them kits over the years .
Guys in business are always looking at things they can market that’s what progress guys do . Driver I remember reading you have run a jaws pipe on one of your old sled ? What was wrong with your stock pipe
see what I mean you most likely got sucked in on the hype of the magic pipe ,
I believe the tki will help but not the ultimate fix , with this new chain and gear maybe not needed at all ,
Just give me some snow so I can ride these things

Its interesting to test stuff, nothing wrong with that. Stock pipe works good and jaws gave some extra. But I would never say you need it.
I don't think your comparison is on point at this matter. TKI makes claims that they can't or don't want to prove and they are showing only what they want to show. But we can prove Jaws claim on dyno any day.
My comparison was not to prove Tom right just to make a point that some guys pay 1050 $ Canadian for a pipe or 150$ for toms part do they need either maybe not but they want it and feel it’s justified in some way and there’s nothing wrong with that . I honestly haven’t watched that video of toms because I eliminated that 2 piece shaft as soon as i got my sled last November. Give Tom a break bud he’s just trying to make a living providing guys with good quality made in the USA parts
like i said previously, give tom a call or email him instead of assuming he is wrong or just trying to make a buck. he told me some interesting things regarding doo's r&d on the two piece driveshaft and maybe he'll share that with you.
in terms of useless or nearly useless stuff that sledders buy especially in terms of money spent vs any gains the list is long--cans, belt drives, big wheels, pipes, etc.
Well, I don't know about "a problem not existing" but when I opened my case with 250 miles on it, and making sure the chain was adjusted correctly during that time, and found substantial wear and scratches in the case and cover around the bottom sprocket; something is moving. Funny, no marks around the top sprocket... I can pull open my '19 with 4800 miles on it and there are no marks or scratches around the bottom sprocket area.
I think the new sprocket will help, not grenade the sprocket at least, but it will transfer the stress elsewhere. I think it will just move chain problems further into the future.... Good luck, run what you want.
