Duramax7man7 505 #1 Posted August 28, 2017 I broke the chain on this snow thrower at the end of this past snow season and am going to be replacing the chain, drive bearings and potentially the idler sprockets if needed... Questions: 1. Are there better versions of the bearings (#110-569) 2. Do all of these sprockets have bearings in them or simply bushing style? (#93-1614) 3. Are there better versions of this Idler sprocket with actual tough bearings in them? Thanks Share this post Link to post Share on other sites
