The old beat up 70 tooth 1 1/2" wide rear pulley that came off my 86 fxrs has a center hole which is 2 1/4" at the hub side and then is 2" on the outside,I cant find an oem# on it,does anyone know what kind of pulley this is?? I have a 136 tooth belt.The local dealership says it came stock with a oem#40221-85A pulley but all the pics of these pulleys Ive seen have a center hole which is 2" straight through with no 2 1/4" offset....Also does anyone know how to get those 5 recessed alan head bolts off the rear brake rotor? why they didnt use a hex bolt is beyond me ,Thanx for your input
