well the rings would never ride that high anyway...and I am sure the stock sleeves are cast into the aluminum so that they could not shift.
sucks about the pressed on gear slipping but it looks like it will never slip again after welding it on.
I would say you took care of the major stuff and should have a very dependable ride for years

 

Its not about the rings riding that high. The problem with that engineering is you can't nikasil the bore or go larger because of that lip. The newer style nikasil bore can be bored out for a larger piston at $75. I had to spend over $500 to get these new sleeves pressed in. If you're motor is damaged its extremely expensive to repair with this style. The newer 850 and 1000 motors are nikasil and can be bored and replated with nikasil. JE offers larger bore pistons for the 850 if anyone is interested. There isn't much to gain from the larger bore though. The only concern I have now is the key on the cam timing gear. If that holds and doesn't shear then this should definitely be a dependable motor for years. Also, I noticed people have cracked frames and the plate that receives the front drive shaft. Yokochrist has replaced his with a billet one. He knows a guy who sells them if anyone runs into that issue.

 

I had the crank shift on my 07 harley ultra because of the way they went with a press fit assy between the flyweights instead of the taper fit with nuts like they where before.
sent it out to darkhorse and had them replace the crank pin with a locking design and have been good ever since...sucks to have to spend money to correct factory re-engineering

 

Sorry to hear about your troubles, Polaris really needs to step up to the plate on this as it seems to be widespread.

 

well they want to sell you a new cylinder ....a lot of snow machines are the same...non bore-able.
we resleaved a lot of snow machines when I worked at a shop.

 

Yea, new cylinders are over a grand. Like I said though the newer style is better. Unfortunately Polaris is making all these changes after seeing all these issues happen to their customers. Basically we're beta testing the machines for them.

 

I also replaced by pinion holder with the billet one when it blew apart, much nicer set up, and just bought a can am 1000, still have the scram but might sell it, just worried my rear diff on the can am will go once i do and dont have a back up quad

 

Yoko said the 2015 Can Am offers a HD rear diff. Can Am is pretty cool about meeting the needs of the Extreme Mudder Market.

 

Im sorry, but if you have a 2013, how come you did not let warranty take care of this?

 

Polaris would have put it back to stock specs then he would have had the same problem later on probably after the warrenty was out. Much better the way he has done it, should have been like this from the factory...........

 

as far as i know, they are replacing with the updated crank. not the one with the pressed on gear.

 

If they are doing that then that means they know they have a defect...........and should really do a recall before they have motors granade! like could happen with piston to valve situations as pictured..... Hope my 2014 is like you say from the factory, fingers crossed lol.

 

^ i agree, im hoping to pick mine up from the dealer this week. its there getting a new style crank. Polaris si covering the part, but not the labor. I may pursue money from Polaris from other means. Ill have to gather info from here to get a list of how many machines on this forum have been affected. This si BS that we have to pay to fix a design flaw that they know is there.

 

Totally agree, they should have to cover the full bill. Best bet is to get enough people together to make this a headache for Polaris.

 

Have all of you folks with the spun timing gear reported it to nhtsa yet??

Just did it, Thanks Brian!

 

So if you're jumping ship from Polaris, what make are you going with? Honda's are bullet proof, but most of the utility ATVs have the solid axle and your butt is pretty sore after a day riding. Only the Rincon and automatic Rancher have the IRS, and neither are very powerful. The Grizzlys are probably reliable, but I've heard they're also a little unstable. I like to keep the shiny side up. I've heard the reliability on the Can Ams is questionable. I don't know much about the Kawasakis, but I've heard good things about the King Quad.

 

I don't think NHTSA is the right place to complain. They're focused on highway vehicles and safety, not mechanical problems. However If I were in this situation I would be sending a very carefully worded letter to Polaris documenting all the costs and send copies to the consumer protection departments in your state http://www.illinoisattorneygeneral.gov/consumers/filecomplaint.htmland Minnesota http://www.ag.state.mn.us/consumer/complaint.asp http://www.mass.gov/ago/bureaus/public-protection-and-advocacy/the-consumer-protection-division/. This is clearly a manufacturing flaw and your state consumer protection division is more likely to help you out. I can't say Polaris will pay you back, but they'll pay a whole lot more attention if the state attornies general are involved. Especially if you can show this is a common problem.

All I know is that they've rectified issues with OHRVs in the past by instituting recalls particularly if there is a safety concern. A potentially exploding engine is a safety concern. I've never seen the AG in my state or a letter to Polaris do that before.
