(refer to lifting/safety section)
6. If the wheel and shaft were shipped unassembled, you must now install the shaft in the wheel.
a. First use solvent to clean the protective coating off the shaft. Check all surfaces for corrosion or nicks and clean if necessary
with fine emery cloth or a stone. After thoroughly cleaning the shaft with solvent, do not touch it with bare hands as
perspiration can cause rust or pitting over time.
b. Remove keys from the shaft.
c. Clean the inside of the wheel bore with solvent. Make sure the setscrews will not interfere when inserting the shaft into the
wheel bore.
d. Insert the shaft into the wheel from the back side of the wheel.
e. When the shaft is flush with the wheel hub (Arr. 1, 9 and 8), dress the key if necessary, insert into the keyway and tighten
the wheel setscrews.
f. For Arrangement 3 fans, refer to the drawing for appropriate wheel and shaft dimensional relationship.
g. Check the assembly drawing to make sure that the wheel and shaft have been assembled correctly.
7. The rotor can now be installed in the housing. Slide the bearings on if they are solid
pillowblocks or loosely mount the bottom halves if they are split. Inlet vanes and/
or inlet funnels may need to be installed over the shaft before installing and bolting
the bearings to their supports (Arr. 3 and 7). Insert the inlets into the wheel inlet and
tie them off for lifting and placing in the housing. Refer to steps 8 and 9 for order of
assembly of components for double width and single width fans. The shaft should
be cleaned and oiled where it will contact the bearings. Carefully lower the shaft
assembly into the bearings. Use care when lowering the shaft onto the bearings
so thrust bearings, collars and liners are not damaged due to misalignment. The
bearing housing should be parallel to the axis of the shaft to prevent loads caused by
misalignment. Precision shim bearings as required. Lock bearings. Be sure expansion
bearing (if supplied) is set to allow for thermal growth. Refer to bearing installation
instructions in this installation manual.
8. Arrangement 3 (split-housed) units:
a. Parts on a DWDI unit are assembled in the following order as viewed from opposite
drive side: bearing bar assembly (or independent pedestal) and opposite bearing,
funnel (housing side), wheel (housing side), funnel, drive side bearing bar assembly
(pedestal), drive bearing and sheaves or coupling. Mount bearing bar assembly to
housing. Center wheel in funnels.
b. Assemble parts in above order on shaft.
c. Proceed with connection of the shaft assembly to supports in step 7 above.

Mount bearing bar assembly to housing.
Refer to the wheel-funnel overlap section.
a. Assemble parts in above order on shaft.
b. Proceed with connection of the shaft assembly to supports in step 7.
10. Install motor on the base if applicable. Carefully align shafts for drive installation. After the fan is leveled, prior to grouting,
back off leveling nuts if used.
