UPDATE: motor is pulled and torn apart. Everything inside the motor is perfect......except center bearing on crankshaft is seized and does not turn. New engine on order.
HAS ANYONE EXPERIENCED A 2019 AXYS 850 ENGINE FAILURE ?

So a poor cylinder finish and engines failing already with crank bearing issues isn't enough? I guess we all have different tolerance levels. I am just very happy with my decision to change brands. I wish I could trust Polaris because I love the chassis but they burned that bridge for me. My bet is, I am not alone.
This is really unfortunate. Just think the customers Polaris would have if their quality was the best. That chassis though just keeps me coming back. And I have a really good dealer that will do compression and leak down tests a d replace top end for me before I get stranded somewhere.

My 14 went to three different dealers, over a dozen visits to get the TPS right. I used to drop it off Monday and pick it up Friday while they attempted to get it right. My closest dealer probably shouldn't even sell sleds. They were trying but somehow missed it over and over again. Next closest dealer replaced worn clutch rollers but, that wasn't it, third dealer, now almost 2 hours away, managed to get it fixed.
I went for an Axys anyway. It blew up at 1100 miles. Replaced under warranty but at 1100 miles it had already needed two primary clutch rebuilds, a new motor, power valve cable broke, which was missed by the dealer that replaced the engine. They wanted to blame the 7000 rpm max with a new engine on the clutch again.
Bottom line, local support for Polaris in my area is pretty bad. Ski Doo is the best local dealer but I can't ride those wobble buggies. I have a great Cat dealer 1.5 hrs drive from home. Fortunately, I haven't need them much.
I was hoping the 850 was going to be the reliability revolution they claimed so I could jump back on an Axys. That isn't looking too promising right now so probably another new Cat next year.
I'm with you on the doo. How does that Cat handle compared to Axys. Must not be quite as nimble if your looking to someday get back on a Axys?
I actually love the way the Cat handles. I also love the 3" track and premium shocks that came on it. I can feel the weight difference though. The Axys is like a toy, so light, easier to get unstuck by yourself, easier to load/unload, easier to just throw around in the tight trees and a side hilling monster. Lighter is better IMO and the 30-40 lb difference is immediately noticeable. I also like the narrow bodywork, my Cat is just a little fat width wise and weight wise. I have actually taken it more technical places than I could get the Axys. Very predictable like the Poo and better traction from the 3" claw.
Thanks for your feedback. Sounds like a fun sled much like the Axys but a little fatter.
Not to rub it in, way OT in the Polaris forum but, the Suzuki motor in my Mtn Cat also has way better power than my 800 Axys ever did... which is nice.

Hate to totally rain on all the superstitious mumbo jumbo and rumors of fiery hell back by stories from friends of friends who heard from a guy that the 850 is a 2007 rev in disguise. But here in the mountains of sw Montana there is a 850 alive and well with over 300 miles of aggressive riding. Other than the occasional hard start during the break in period (3/4 pulls) this charming little Polaris born on a full moon, is turning 8250 at 9500ft with 68 gram weights. Time will tell if I'm over optimistic, but until we have real people with real examples of engine failure try and relax. If there is a problem we will find out alot sooner if people spend more time riding and less time typing.

Well, actually there are several reported failures by real people already. That is more reported engine failures than I see on the Cat or Doo forums...
When did cat switch to building their own? I thought they were building their own motors now?
2018 is the new motor. I have the rare 2017 Mtn Cat, all the new features with the old motor. I am not a fan of beta testing new motors for any manufacturer. The new Cat motor is mostly a copy of the old with an updated fuel system. Seems like they are holding up well but I am waiting to see how those do for two seasons as well before I buy.

Is this the one that was riding up Meadow last weekend? He was with 1 or 2 other 850's that day that both seemed to run great. I did see one other one on the hook that day, but none that had your sticker on the hood.
I think the locating pin migrated and the ring spun.
My 2019 850 is on its 4th engine in 400 km.
4th ones the charm I hope. Been going good since I got the 2020 crate engine!
Yay Polaris

You live in a state with lemon laws hopefully?
shlt, that SUCKS.
Nah. I bought it used. Last owner took the brunt of the downtime. I only popped one motor and now she’s running good with the 2020 motor. I’m happy with the purchase.
