Page: 112 / 134

Installing Inner Housing Components (continued)
1. Assemble the inner housing if it was disassembled; refer to Installing the
Rotor Shaft (page 6–11) .
2. Position the inner housing assembly on supports with the rotor shaft pointing
up. Carefully lower the outer housing around inner housing assembly.
Place
14.3 mm (9/16 inch) thick spacers between the supports and the
outer housing. This arrangement will align and stabilize the inner and outer
housing assemblies during the service procedure; refer to
Figure 44 .
3. Install the 4 support fins (item 5) as follows:
A. Position the support fins between the inner and outer housing.
B. Determine if one or more shims are required to remove any space
between a support fin and the outer housing.
Note: If multiple shims were required between a support fin and the outer
housing, center the inner housing in the outer housing by dividing the
number of shims evenly on each side of the assembly.
C. Use medium strength thread locking compound and install all 8 cap
screws finger tight. Tighten the cap screws from 10 to 11 N·m (7 to
8 ft-lb) .
4. Install the 24 stator vanes (item 2) as follows:
A. Position a vane between the inner and outer housing. The rounded
edge of the vane must be upward (toward the front of the blower) and its
mounting lugs toward the inner housing.
B. Tilt the vane and engage the mounting lugs with the inner housing holes.
While keeping the vane lugs in the inner housing holes, rotate the vane to
align the threaded hole of the vane with outer housing hole.
IMPORTANT
Be very careful not to cross-thread the stator vane cap screws
during assembly.
Note: New stator vane cap screws have a thread locking compound
pre-applied. If installing a used stator vane cap screw, apply a medium
strength thread locking compound during assembly.
C. Install a cap screw (item 3) into the threads of the stator vane and tighten
the screw finger tight.
D. Repeat steps A – C for all of the remaining stator vanes.
IMPORTANT
Overtightening the stator vane screws can damage the threads in
the stator vanes. Use hand tools only and do not overtighten the
stator vane cap screws.
E. Use a crossing pattern and tighten the stator vane cap screws from 1.2 to
1.4 N·m (10 to 12 in-lb) .
5. Check each stator vane and support fin for looseness. Correct any loose,
improperly installed, or damaged stator vane or support fin before proceeding.
