4xbill 2 Posted April 15, 2007 Are these bearings sealed/non-greasable? This deck is realllly loud, scary loud. MFG 1691199. Thanks. Share this post Link to post Share on other sites
carbuff713 0 Posted April 15, 2007 The bearings are sealed. They are good for at least 500 hours. The grease just keeps out moisture. Take off the belt and spin each blade to find the bad bearing. The bearings are easy to replace. David Share this post Link to post Share on other sites
