fishingstararlake 1 #1 Posted March 17, 2014 I have a 520 h and need to replace the idler pulley transaxles drive. All the parts diagrams are not showing it. It started to make noise last fall and checked it out then and got some chain lube in it. Now I would like to replace it and can't find it. Can anybody help me out?

illinilefttackle 399 #6 Posted March 17, 2014 Does it look like this?-if it is made up of two sides, riveted together, capturing a bearing in the middle, you are better off replacing the bearing-the new stens pulley, pictured also, has a much smaller bearing-just drill out the rivets-and replace the bearing-then rivet it back- much stronger-Thanks-Al Share this post Link to post Share on other sites
