Arrived at location on 3/3/22 - Checked over unit. Found grinding noise from top side of unit. Pulled cover found pulley assembly blew apart. Put back together and found top bolt broke inside of shaft and pulley assembly damaged inside due to centrifugal force while coming apart. Will need new pulley assembly as this fix will not last. Secured top bolt in place so unit can be ran until parts arrive. Returned to location on 3/16/22 - Replaced pulley assembly and tested. Found all in working order.
