NOTE: There are (2) common accessory drive assemblies that Detroit used on the series 60 engines with a dual V belt configuration. If your engine has accessory drive PN: 23523996, then you can simply replace the dual V belt pulley with the new 8 groove serpentine pulley provided in this kit. However, if your engine has accessory drive PN: 23509200, the shaft length is 1/4" too short and must be changed out OR the new pulley must be shimmed out in order for the belt to align properly with the other pulleys in the accessory drive system.
