gt14rider 1,159 #1 Posted 3 hours ago Hi all, trouble finding a good 1623. Can get the bearings local. My question is can I use these pop rivets or get solid rivets and peen them over? Thanks Share this post Link to post Share on other sites
Razorback 1,280 #2 Posted 3 hours ago Hmmmmm….. that’s a good question. I think I would go the solid route to possibly be the strongest? Also, you mentioned the bearings. Can you post the details for the bearing for future reference? 1 Share this post Link to post Share on other sites
peter lena 9,859 #3 Posted 2 hours ago @gt14rider regular reference to this bearing issue , personally always go for the WIDE RUBBER SIDE SHIELDS , thats what you want ? unknown grease in there , small flat pocket screwdriver or small flat putty knife , easy removed with no damage at all , pop off both sides , Walmart , lucas x-tra heavy duty green chassis grease , wipe out all original grease , carb cleaner aerosol , flushing , hand pack bearing , reinstall seals , lube is 550 deg flash point , also polyurea rated , so it stays with the issue , done this in every related , pto driven bearing , guess what ? NO WHYINING BEARING NOISE , or related failures , @Razorback , personally love repetitive failures , track it down and kill it , make a change . mule drive bearings also re lubed , no belt squealing , just easy smooth wind up , that pto lever start up area is a GOLD MINE , for operational delight , heim joint end swivel , pete 1 1 Share this post Link to post Share on other sites

Lane Ranger 11,954 #5 Posted 2 hours ago Mike Prodzinski in Minnesota has been rebuilding these #1623 pulleys for several years. I had him redo several of mine. Years ago i bought a bucket of them at ghe Big Show - about 1:3 were still useable. Maybe he can give you some pointers on the rebuild! 1 Share this post Link to post Share on other sites
ri702bill 11,982 #6 Posted 2 hours ago 28 minutes ago, Ed Kennell said: I use small bolts ,lock washers, and nuts....cause I have tons ofem. I agree... I mill off the heads of the rivets and drive the body of the rivets out. Replace the sealed bearing with a new one. Buff the halves on a wire wheel before assembly. I use #5-40 Button head screws - 1/4" or 5/15" long with a dab of blue Loctite on the threads and then the hexnut. This way, they are easily rebuildable later on instead of riveting. a light coat of Rusty metal Primer and a spritz of red - better than new... 2 1 Share this post Link to post Share on other sites
gt14rider 1,159 #7 Posted 1 hour ago @peter lena pete trying to get side shields off started this hole thing ,buggerd up shield, bearng was good, not any more. @razorback I'm going to bearing distributors, called and they have them. So when I get some information I'll let you know. @ri702bill I'll see if I can get some 5-40 button head screws . 1 Share this post Link to post Share on other sites
JoeM 9,817 #8 Posted 1 hour ago There is nothing in those pulleys that has a high level of accuracy. Just a stamping with a bearing in the middle. I did the drill and bolt thing, just to time consuming. Now I take a grinder with a cut wheel and cut 6 slots. I started out using a chisel to bend the tabs but use the press to just push through the tabs. Pop in the new bearing and bend the tabs over. I have done at least a dozen with no problems. Just another option from an old bush mechanic. Share this post Link to post Share on other sites
