Change the bearing before it locks up and spins on the shaft then

That bearing either gets changed seasonally or get serviced in the way that jonlafon described.  The tolerance is so poor the wear happens extremely quickly and even a new free spinning bearing makes little difference to shaft longevity.

While I’ll normally get in stupid arguments with mnstang on green goggler issues I’m with him on this. The Yamaha guys really started this issue because a 1 in 1000 issue drives those dorks into a frenzy. Have I seen a bunch of them that are absolutely smoked? Yes. Have I seen a bunch of sleds with well over 5k miles and the original shaft is completely fine? Yes.

It isn't 1 in 1000 though. I've gone through several shafts on multiple sleds...it's just not something that should be happening.  Bearings are wear items shafts are not.

Why would they? They need it to last 2 seasons. then they can sell you a new shaft and bearings for 500 bucks 

This is essentially arguing they don't care about perceived nor actual quality....FAIL

I think a little green loctite on the shaft and should be good to go.

Yes, disassemble your brand new $20k sled to apply loctite to a critical component. It might work.

If it were that easy there are 2 scenarios:

Cat could do it (apply green loctite) at the factory and has elected not to....FAIL

Cat doesn't acknowledge the core problem at all due to cost/assembly logistics/etc....FAIL

Personally I don't care so much about the rotor... Its the inner race of the bearing wearing out the driveshaft.

What's crazy to me is this isn't some magic fix for a poor design...it's literally just tighter tolerances and Cat apparently couldn't even pull that off???

Dumbfounding that Cat did not address this

Was hoping to get out this weekend but the rain has other plans apparently.

Apparently Nukeproof is being liquidated?

I want an ebike...but not for riding on trails.  Was going to build a 7000w full squish bike to cheat on our local transport trails so that I can ride 10mi to a restaurant at lunch faster than I could drive while getting fresh air and not sweating my ass off.  Trail riding something nimble and light that is forgiving is what I want.

...and yes, I could just ride a motorcycle for the above but another toy sounds like a fun build and unlike a motorcycle I won't kill myself if I ride it to the bar.

That's fair

I have a really hard time with ebikes. To me it defeats the purpose...exercise feels good and is good for you. If I want something motorized I'll grab my motorcycle.

My troy is a 140 rear and 150 mm up front. Some versions come with an available 160mm fork. That would be way overkill for what I typically ride. Only occasionally do I miss 27.5 wheels...the 29 is just so much faster overall in my experience, even if it doesn't feel like it. Then when riding the extremely rocky terrain of north shore upper peninsula the monster truck tires come in quite handy too.

All depends what/where/how you ride though.

Been an avid mountain biker since high school (now 35). We are fortunate to have around 50 miles of singletrack within a 15 min drive of my house and many more within 45 minutes. I'm with many of you in that it has claimed a collar bone, in addition to a nose, two fingers, and two ribs. Of all the motorsports I do, somehow mountain biking has been the most dangerous for me. I do a race exhibition here and there, but I mainly ride for fun.

I have a road bike as well but that mainly gets used for foundational zone2 endurance training both during and off-season on a bike trainer.

Primary ride is a Devinci Troy Carbon 29.

Did he say anything about the “other” big bore engine that was scrapped at the same time the catalyst was put on hold? 

I'm thinking the Catalyst would've won if tunnel flares were installed

Nope watched it yesterday morning.

That's not it

What sled did they allocate the SOTY honors to then?

I'm surprised our resident forum fact fabricator doesn't have constant issues with cooling. When my young nephew rides the R-XC at a constant 15 mph it definitely gets toasty.

I doubt those deflectors even do any deflecting at those speeds, let alone cooling.

Some conditions you can’t avoid it but riding hard keeping the track spinning with studs helps a lot on the procross chassis

Yep that's pretty much my experience. Stay as "brappy" as possible

Keep the track and the water pump spinning.

I put em on because wire scratchers throw shit all over the place... and that's the only reason

 

Do you run studs?

I have a feeling that's a big reason I never seem to have cooling issues except in extreme circumstances (like plowed seasonal roads).

I know you are at least capable of reading and comprehending a products intended purpose...

put some on your RS and tell me how much cooler the sled runs with them... 

It's wild to me those are over $100. I'll take an occasional snowball to the shoulder

So.... as far as the Catalyst goes, what's everyone's take on SnowTrax SOTY episode, saying that the handling and especially rear skid are not up to par with the other manufacturers? I don't pay much attention to it all but suspected that the all new Catalyst would have been chosen #1, sure they would be desperate to give AC some love.

Instead they gave it a design award.

 

Do you have a link to this episode? The last "Real world sled of the year" snow trax episode I can find was 2023.

I do know Snowgoer gave the Catalyst SOTY honors, fwiw.

If anyone with money to buy sleds cared about 1000' radar running, the oems could easily make sleds do that and they'd dominate.  It's not hard.  But the only people who care about radar runs are people that don't even ride.  They're not even snowmobilers just posers.  

This guy pictured his zrt in his driveway, guy lives in cookie cutter suburb shitville beta land with a strip of grass between houses guy can't even ride down his own road.  Radar running the lowest form of competition, not even racing it is speed running you could be slower to the finish line but still "win" wow do you iv inject the soy straight in or??  No matter what mph your sled runs you still have to go home to your beta subdivision every day and come on why is it on the track stand if you were running it all your neighbors would be calling your association just more posing 

I'm dying

Changes in belt length will change the entire calibration because the secondary and primary clutches will be in different points of their shift, relative to each other.

So if someone thinks there is a magic belt length that made their machine so much better, all it proves is their calibration was way off with the other belt.  That's it.

That's not really true in my experience. While the "auto-tensioning" clutches that Cat uses may likely mask improper belt length better than other setups, a belt that is too long will absolutely crush top speed because the primary could be full shift, but the secondary is not (and cannot). Attempting to get the secondary to fully shift in that scenario would just create belt slip, heat, and further loss of top speed.

You can see where the tabs are broken off the bulkhead. They’re part of the bulkhead and not replaceable

Did they break at the weld or is the metal too thin?
