Doug Posted December 23, 2020 Share Posted December 23, 2020 Installing a roller bearing in the 2ndary is really not a true performance gain but a consistency gain for your sleds shifting. Without a bearing or at least delrin washer in the 2ndary results in some erratic shifting and inconsistent performance. On occasion the spring will bind up preventing the 2ndary from fully opening for full shiftout or delay the shifting both normally resulting in the sled overwinding and poor top end. Delrin washers should be the minimum stalled but the roller bearing seems the most consistent. I use a shim washer between the bearing and aluminum clutch sheave as I've seen bearings wear into aluminum in different applications others have not used a shim washer and seen no effect on the aluminum. The bearing gets installed beneath the spring bucket item 9 and the outer clutch sheave. 2 Quote Link to comment Share on other sites More sharing options...
Crnr2Crnr Posted December 24, 2020 Share Posted December 24, 2020 is that primarily a Polaris thing? I don't recall seeing a lot of Cats or Doos doing the delrin or roller bearing - or maybe I've missed those posts. Quote Link to comment Share on other sites More sharing options...

I also do it like Doug said. A washer on the clutch sheave side. And I also sand the cup where the bearing rides with 600 wet paper on a glass surface.

Doug Posted October 24, 2021 Author Share Posted October 24, 2021 If you are looking to buy this bearing just go to Amazon with the information above. Seen where there's a place on a different site that is selling these for $25.00. That place currently does not post over here. I'm all for a little markup but come on.

Doug Posted March 26 Author Share Posted March 26 Guys that are not running a shim under the needle bearing may want to check their clutch. Just pulled this clutch apart to clean it and the clutch is starting to get chatter marks where the bearing ride. This one did not have a shim between the bearing and clutch. Sled had about 1800 miles on. 2 Quote Link to comment Share on other sites More sharing options...
