peter lena 8,632 #7 Posted April 25, 2023 @tallen4392 also check out your related idler pulley on that , typically those tiny original bearings , get funky / rough noisy , tractor supply has a same size unit with bigger rubber side shields , insert a short bronze bushing to make it a size to size fit . personally would pop off the bearing shields , clean out and re grease with a hi temp grease. reinstall shields , also lubricate related chassis linkage / lever areas , grease / oil . make for quiet / smooth operation . guy I just sold a horse to , thought the clutch pedal was different , turned out he was used to stiff / rusty linkage , marveled at its smooth engagement . gave him a list to follow , probably never looked at again , pete Share this post Link to post Share on other sites

clueless 3,002 #9 Posted April 25, 2023 Just buy the OEM 7473 belt, it's the correct belt and it fits properly, it cost more but it should last you another 30+ years . 2 Share this post Link to post Share on other sites
