Typical Procedure for Disassembling a Ford IAR AC Generator

Always have a clean and organized work area. The tools required to disassemble a Ford IAR AC generator are rags, T20 torx screwdriver, plastic hammer, arbor press, 100-watt soldering iron, soft-jawed vise, safety glasses, and an assortment of sockets or nut drivers.

Using the torx screwdriver, remove the four attaching screws that hold the regulator to the ac generator housing.

Remove the regulator and brush assembly as a unit.

Using the torx screwdriver, remove the two screws that attach the regulator to the brush holder. Then separate the regulator from the brush holder.

Scribe or mark the two end housings and the stator core for reference during re-assembly.

Remove the three through bolts that secure the two housings.

Separate the front housing from the rear housing. The rotor will come out with the front housing, and the stator will stay in the rear housing. It may be necessary to tap the front housing with the plastic hammer to get the two halves to separate.
