I would like to thank everyone for your input on the pinion plate failure. I would like to see someone high up that works for polaris for a comment on this on going problem and fix it. That would be the right thing to do. What ever happened to quality control in America?

Pinion plate was updated in 2018.

This site is unaffiliated with Polaris, so I don’t think a Polaris rep will comment. Not sure what you want them to say anyway. Pinion plate has been updated. For older models, you can either buy a cast steel OEM one or an aftermarket billet aluminum. Considering the number of units that are sold and that are not upgraded, the aluminum pinion, although not perfect, does perform adequately more times than not.

If it broke that easy I suspect it may have already been loose and had some play in the fasteners. I've seen pics of a few that were caught before they came completely unglued. I'd advice anyone with a pre-18 machine to check the pinion as a regular part of maintenance if they aren't gonna replace the cover. If one or more of the bolts are found loose, put a drop of blue loctite on the threads and torque to spec.
The above might not prevent the failure but it sure couldn't hurt to try to catch it BEFORE it explodes.

Yeah all the screws were tight its just a cheep pinion cover. It might have had a Crack in the cover from the previous ride to break loose that easy

Yep the fixed the problem in 2016 and 2018 and skipped 2017

Where did you get that information from? Pinion cover wasn’t changed to steel until 2018. Prior to that they were aluminum with known breakage problems. 2016 and 2017 shared the exact same part number until it was recently superseded by the steel pinion cover part number.

Then it’s all misinformation. I do read and provide factual information. I’ve said it twice now, I’ll say it a third time and I’m sure there are many people on this forum that will confirm. Pinion cover was changed to steel in 2018 on the 850/1000 models. Prior to that, they were aluminum and known to break. 2009-2014 used the long pinion cover. 2015-present uses the short pinion cover.

Is this correct that the later steel OEM is a direct fit replacement for my 2017 Sportsman 850?

Yes

I’m offended Mel 😉

I do read and provide factual information.

My recommendation though would be to get a billet aluminum from Cecco or Custom MotoQuad. I still think those are better than the cast steel OEM, and they are proven to work.

Not at all G, I simply want to be sure I’m understanding correctly. Posts have been misinterpreted a couple times on the Internet

You need to post this in a new thread of your own and tell what happened with what machine your working on.
