four retaining bolts from the bearing retainer cap.
Removing Shaft
3. To remove the shaft from the assembly, tap the opposite
end of the shaft with a soft hammer. After the shaft has
been removed, clean all parts in clean solvent.
Removing Oil Seal
4. Using a punch, remove the oil seal from the evaporator
end of the assembly. With the seal removed, clean the
housing in solvent.

aged, it must be repaired or replaced.

bearing races for wear or damage.

in the center of the shaft.
