Is there any difference in the fixed flange on the primary clutch between '17- '22? 3 different part #'s in fiche. Later model part #'s list for 1/2 as much. Thanks!

Yeah they starts putting cooling fins on the back of the sheave in 2019 I believe it was.

That was the secondary, I think.

Yes, you’re right it was the secondary that got the fins, not the primary.

Primary fixed sheave got the fins in 2018, did not have them in 2017

OP: what are you looking to do - take part of one clutch and add the parts to another?

This was my thinking as well

Primary fixed sheave got the fins in 2018, did not have them in 2017

thats what it is....fin on primary in 2018 when i bought my freeride , then secondary in 2019...along with the vent kit

Ok guys! I just received the latest fixed sheave
#417224332. Two things: it does have fins on the back and it's made in Taiwan. So, I ordered the '17 fixed sheave (#417224155)and will compare. This part # may have been superceded by #417224278 or the one list above.

pics in the link below of the 2022 (the one you just bought) and the fixed from the 2019's fyi

something interesting about my 2022

so i pulled the pdrive clutch off of my 2022 backcountry 850 to change some parts inside it lol and when looking on the backside i noticed that it is a completely different stationary sheave........ info on the part change and or speculation is welcome :) i apologize if this not the first year...

So, now my question is will this new fixed flange fit my '17 crank and outer primary components?

It should. The finned sheave was listed as an update for the 2017 sleds.

the 850 cranks are all notched the same on the snub. the alignment marks may be different on the new fixed compared to your 17 so keep that in mind
