4. Center the evaporator blower in the blower housing with equal overlap on both inlet orifices
and tighten the hub pinch bolts (see “Evaporator Fan Blower Alignment” above).
5. Make sure the key is in place in the condenser end of the fan shaft.
6. Place the upper condenser blower on the fan shaft and slide it into position to where its pulley
is aligned correctly with the other pulleys and tighten the hub pinch bolts.
7. Install the upper condenser inlet orifice. Center it in the upper condenser blower and tighten
the mounting hardware (see “Condenser Inlet Orifice Alignment” above).
8. Install the fan drive belt. See “Fan Drive Belt” in the Engine Maintenance Chapter.
Lower Condenser Blower Assembly
The lower condenser blower assembly contains special sealed bearings. The bearings should be
checked when the belt is replaced. Spin the lower condenser blower with the belt removed and
listen. Unusually loud bearing noise indicates the lower condenser blower bearings should be
replaced.
Removal
1. Remove the fan drive belt. See “Fan Drive Belt” in the Engine Maintenance Chapter.
2. Remove the mounting hardware for the lower condenser inlet orifice and remove it.
3. Remove the hardware that fastens the blower spindle to the spindle mounting bracket and
remove the lower condenser blower assembly.
Disassembly
1. Remove the snap ring.
2. Remove the spindle and wave washers from the blower hub.
3. Remove the bearings from the blower hub with a hammer and punch.
4. Clean and inspect the parts, but do not clean the bearings in solvent. Replace the parts that
show significant wear or damage.
