7.17.2 Disassemble the Evaporator Fan Assembly
1. Attach a spanner wrench to the two 1/4-20 holes located in the fan hub. Loosen the 5/8-18 shaft nut by
holding the spanner wrench stationary and turning the 5/8-18 nut counter-clockwise (see Figure 7.11 ).
2. Remove the spanner wrench. Use a universal wheel puller and remove the fan from the shaft. Remove the
washers and key.
3. Remove the four 1/4-20 x 3/4 long bolts that are located under the fan that support the motor and stator
housing. Remove the motor and plastic spacer.
7.17.3 Assemble the Evaporator Fan Assembly
1. Assemble the motor and plastic spacer onto the stator.
NOTE
When removing the black nylon evaporator fan blade, care must be taken to assure that the blade is not
damaged. In the past, it was a common practice to insert a screwdriver between the fan blades to keep it from
turning. This practice can no longer be used, as the blade is made up of a material that will be damaged. It is
recommended that an impact wrench be used when removing the blade. Do not use the impact wrench when
reinstalling, as galling of the stainless steel shaft can occur.
2. Apply Loctite to the 1/4-20 x 3/4 long bolts and torque to 0.81 mkg (70 inch-pounds).
3. Place one 5/8 flat washer on the shoulder of the fan motor shaft. Insert the key in the keyway and lubricate
the fan motor shaft and threads with a graphite-oil solution (such as Never-seez).
4. Install the fan onto the motor shaft. Place one 5/8 flat washer with a 5/8-18 locknut onto the motor shaft and
torque to 40 foot-pounds.
