I ORDERED A TOTALLY NEW IDLER PULLEY ASSEMBLY, THAT IS SUPPOSED TO LAST LONGER, THIS ONE HAD BEEN REBUILT WITH A NEW BEARING INSTALLED, BUT LASTED LESS THAN 15,000 MILES. THE NEW BRACKET HAS A SQUARE HOLE BELOW THE ADJUSTING SLOT, THAT ALLOWS A RATCHET EXTENSION TO BE INSERTED, THIS REALLY HELPS IN ADJUSTING THE BELT, BUT IS A LITTLE HARD TO INSERT DUE TO THE HEATER HOSE PIPES THAT PASS DIRECTLY IN FRONT OF THE BRACKET, SEE THE NEXT PHOTO.
