3208 Governor Housings Early production governor housings (4N570, 6N1744 and 6N7524) did not have a bushing (1) in the outer bore for the governor control shaft. Later production governor housings do have a bushing (1) in the outer bore, as shown, but neither the early production or the later production governor housings have a bushing in inner bore (A) that is also for the governor control shaft. The procedures given in this instruction are for the use of the FT1525 Alignment Pin, FT1526 Salvage Fixture and the FT1698 Bearing Installation Tool. These tools are needed to install a bushing in the inner and/or outer bore for the governor control shaft in either the early production or later production 3208 governor housings. Use the procedure given in this instruction that is needed for the specific governor housing to be reconditioned.
