Geared Fan Driveshaft

Does anyone have an NSN or PN for the Geared Fan Driveshaft on a M1152A1? Actually, a full diagram would be helpful detailing NSN's for that entire system from the pulley on the pump to the fan clutch. But specifically I need something for the Geared Fan Driveshaft. I've searched TM 9-2320-387-24P cover to cover and didn't come across this... I did however find the Maintenance procedures in Volume 1 of the same edition. Any help on this matter is greatly appreciated.
