trying to put new bearings and seals in the fan gearbox on a 763. i got the part that holds the fan apart but i cant figure out how to get the other half apart, the part with the pully. does anyone have a picture of the inside or know how the shaft comes out? i took the bolt out if the bottom that holds the gear on but the gear won't move and i dont dare try pressing me cause i dont know if there are snap rings in it. does it press out from the bearing side or pulley side?
