SUBJECT:
NEW 120 AMP GENERATOR, REAR GENERATOR MOUNTING BRACKET, SERPENTINE BELT AND
TENSIONER ASSEMBLY
MODELS AFFECTED: 1985 FWD DEVILLES AND FLEETWOODS
FIGURE 1 - Generator drive end frame
All Front Wheel Drive Fleetwoods and Devilles built after VIN breakpoint 321327 are equipped with a 120 amp 17 SI generator, a new design rear
generator bracket, serpentine belt and belt tensioner assembly. Vehicles built at or before VIN breakpoint 321327 are equipped with a 108 amp 17 SI
generator. Vehicles equipped with the 120 amp generator can be identified by a VIN breakpoint greater than 321327 and the 120 amp specification and
P/N 1105656 marked on the end of the generator drive end frame (see Figure 1).
IMPORTANT:
Due to a larger pulley size and different rear generator mounting bracket configuration, the 120 amp 17 SI generator, new rear
generator mounting bracket, serpentine belt and belt tensioner assembly are not interchangeable with respective components on
vehicles with the 108 amp 17 SI generator built at or before VIN breakpoint 321327.
The new 120 amp generator uses a split tapered collar to retain the generator pulley. The collar is not removable. Therefore, to service any drive end
frame components, it is necessary to replace all of the drive end frame components as an assembly using service kit P/N 10495628 which contains the
parts listed below.
