ASSEMBLY WITH BUSHING
Clean all mating surfaces between hub, bushing and shaft. All
grease and lubricant should be removed, leaving the mating
surfaces dry.
If there is no shoulder on shaft to prevent bushing from sliding
down shaft, slide spacer/sleeve (not provided) on shaft before
bushing or use a thrust retainer (optional equipment) on top of
hub. Slide bushing and key onto shaft until flush with end of
shaft. The shaft size determines the bushing type (Q2 or R2).
Lock bushing on shaft by tightening the set screw in flange
with an Allen Wrench. (Note: Q2 bushings have no set screws.)
Line up key and set hub on bushing. Engage the three (3) cap
screws in flange of bushing into hub spool, using a torque
wrench with a socket, and tighten evenly. Use the following
table to determine the proper tools and torque values.
ASSEMBLY WITH STRAIGHT SHAFT
(NO BUSHING)
Clean all mating surfaces between the hub and the shaft. If
there is no shoulder on shaft to prevent hub from sliding down
shaft, slide spacer/sleeve (not provided) on shaft before hub or
use a thrust retainer (optional equipment) on top of hub. Install
key in shaft. Line up key and keyway and set hub on shaft.
Tighten set screw(s) in hub.
ASSEMBLY WITH TAPERED SHAFT
(NO BUSHING REQUIRED)
Clean all mating surfaces between the hub and shaft. Coat all
mating surfaces with an anti-seize or lubricating compound.
Align keyways and install hub. Install retainer plate and cap
screw(s) with lock washer(s). Shaft size determines what size
cap screw is necessary. Using a torque wrench with a socket,
evenly tighten cap screw to recommended standard per table
below.
NOTE: Retaining arrangement varies with gear shaft design.

Installation Manual 3000B Page 3 of 9 May 2012
LOOSEN SCREWS AND REMOVE RINGS
Unscrew 3/8” blade socket cap screws until flush with inside of
socket. Unscrew jam nuts back to near heads of cap screws. Re-
move lock screws in top and bottom retainer rings (See Figure 1).
Mark ring and blade socket at center to indicate where lock screw
goes. Use retainer ring tool to remove individual blade retainer
ring halves. Insert end of tool into hole in end of retainer ring half
and pry ring out of blade socket. (Note: If tool is not available, a
1/4” hook bent on the end of a piece of 1/8” diameter wire
works).
LOCK SCREW
INSTALLATION OF TUF-LITE II®
BLADES IN TUF-LITE® HUBS
To mount Tuf-Lite II® blades into the original Tuf-Lite® blade
sockets, use our H-blade adapter (P/N K2300). Install both halves
of adapter over blade. Make sure flange of blade is against inside
shoulder of adapter. Tighten 3/8” cap screws to 30-35 ft-lb torque
(See Figure 2).
Figure 1
Figure 2
BLADE INSTALLATION
Place blade in hub socket. Insert blade shank into socket far
enough to allow blade retainer ring halves to be “snapped” into
place (See Figure 3). If you are using the H-blade adapter with
Tuf-Lite II® blades, make sure that the split in the adapter is
horizontal. Position the blades’ thick leading edge to the left
and thin trailing edge to the right as you stand at the end of the
blade.
INSTALL RETAINER RINGS
Insert one end of retainer ring into groove and rotate ring into
groove with end of screwdriver as shown in Figure 4.
Figure 3
Figure 4

Installation Manual 3000B Page 4 of 9 May 2012
Make sure rings are seated properly in groove and the mark
drawn on ring lines up with the mark on the socket. Gaps be-
tween upper and lower retainer halves should be equal. Install
lock screw into each retainer ring half. Hold ring in place with
screwdriver while tightening screws. Hand tighten the blade
socket cap screws. DO NOT TIGHTEN JAM NUTS.
INSTALL SEVERE DUTY RETAINING
RING (OPTIONAL EQUIPMENT)
If included, place severe duty retainer (SDR as shown in Figure
5A; for old recessed-ear hubs, both the old 65289 SDR and the
D3246 retro-fit spacer are required) into the blade socket cavity
by either pushing it directly into position on top of socket or by
pushing it into the blade socket at 90° to one side and then rotat-
ing it into position on top (12:00) side. Refer to the following
Figures 5A, 5B or 5C.

KIT K2200 FOR
(1) SDR ASSEMBLY
It may be necessary to partially loosen the four (4) blade socket
cap screws (labels 1 & 2 in Figure 5B and/or jostle the blade
slightly to initially place the SDR part into its assigned position
as shown in Figure 5B or 5C.
Now insert the two (2) 3/8” cap screws (labeled 3 in Figure 5B
or 5C) and lock washers into the SDR and finger tighten only.
Note A: The four (4) blade socket cap screws and the two (2) SDR cap
screws are maintained finger-tight until the blade(s) is (are) adjusted for
both blade pitch and blade track. After a gradual trial & error series of
adjustments, occurring in subsequent portions of this manual, these same
cap screws shall at completion achieve final tightness to specified torque
values.

Installation Manual 3000B Page 5 of 9 May 2012
SET PITCH AND TRACK
Use Hudson’s EXACT-A-PITCH® digital protractor (See Figure
6) or a bubble protractor to set blade pitch. Mount protractor on a
flat bar as a base and place it approximately 1” from tip of blade.
Note pitch on protractor. Rotate fan 360º, noting high and low
pitch readings. Locate place where pitch reading is at mid-point
between high and low readings, and set pitch at that point.
Rotate blade in socket until digital protractor shows specified
pitch angle to within +/-0.2º. Fan pitch angle is shown on fan
specification sheet for design duty. After desired pitch angle is
set, raise and lower end of fan blade and find mid-point of blade
travel. Hold blade at the mid-point and pull blade outward so it
sits against retainer rings.
Check to see that blade retainer rings are properly seated in both
hub and blades grooves. It may be necessary to back cap screws
off about one turn and re-tighten them in order to force ring to fit
properly in groove.
Start tightening the four blade socket cap screws by alternating
the sequence of tightening (like tightening lug nuts on a car
wheel). The torque applied to any one cap screw shall be no
more than 5 ft-lb, greater than the torque on any of the other (3)
cap screws during the tightening process. All cap screws are to
be tightened to 15-20 ft-lb. Make sure shoulder on blade neck fits
tightly into and against retainer ring. DO NOT OVERTIGHTEN
CAP SCREWS. After cap screws are tight, tighten jam nuts
against socket to 15-20 ft-lb.
Note B: If a severe duty retainer (SDR, Figure 5A) is used, it
may be necessary to loosen the SDR fasteners as necessary for
proper retainer ring seating at the outset. See cap screws labeled
as (3) in Figure 5B or 5C.
Figure 6
When bolts are tightened, hold a pencil against top end of blade
and mark the level onto a fixed object, such as a pole or the fan
ring.
Install remaining blades at same place as first blade, following
the instructions above. After tightening cap screws, mark top
end of each blade in same place first blade was marked. If
marks differ by more than 3/4”, adjust blade.
Note C: It is more important to positively seat the retainer ring
pair into the blade shank ring groove than to achieve perfectly
consistent tracking between all blades. If there is a conflict in
achieving both blade seating and blade tracking, ignore the
tracking specification.
CHECK TRACK
After fan is installed in fan stack cylinder ring, outline the top
side of each blade onto fan stack cylinder ring with a marker
(See Figure 7). The difference between levels of highest and
lowest outlines should not be more than 3/4”. To raise blade
track, loosen blade socket cap screws on top half of socket and
tighten cap screws on bottom half. To lower blade track, loosen
bottom screws and tighten top ones. Tighten 3/8” cap screws to
15-20 ft-lb torque. Re-tighten jam nuts after adjustment.
Note D: It is more important to positively seat the retainer
ring pair into the blade shank ring groove than to achieve
perfectly consistent tracking between all blades. If there is a
conflict in achieving both blade seating and blade tracking,
ignore the tracking specification.

COMPLETE SEVERE DUTY RETAIN-
ER (SDR) INSTALLATION (OPTIONAL
EQUIPMENT)
If the SDR is installed, the blade socket jam nuts & blade
socket cap screws (labeled 1 and 2 in Figure 5B, 5C) must
now be finally tightened to the recommended standard of 15
ft-lbs (lubricated) or 20 ft-lbs (dry) and the SDR cap screws
(labeled 3 in Figure 5B, 5C) must now be finally tightened to
20 ft-lbs (lubricated) or 25 ft-lbs (dry).
FINAL INSTALLATION CHECK
(IMPORTANT)
Double check and make final adjustments as necessary by
essentially going through the provisions of those paragraphs
entitled “Blade Installation” on page 3 through “Complete
Severe Duty Retainer Installation” on page 6 inclusively.
In so doing, one shall check the following setup criteria for
all blade positions:
0. Blade seated in hub socket.
1. Retainer rings fully seated in blade neck grooves and
hub socket grooves.
2. If applicable, SDR’s properly mounted into hub sockets
and onto blade necks.
3. Blade pitch set within +/-0.2 degrees of design value.
4. Tracking, if possible (see note above), set within +/-0.3
75” (3/4” max spread).
5. All (4 per blade pos) blade retainer cap screws torqued
to spec, 15 ft-lbs (lubricated) or 20 ft-lbs (dry).
6. All (4 per blade pos) blade retainer cap screws jam nuts
torqued to spec, 15 ft-lbs (lubricated) or 20 ft-lbs (dry).
7. If applicable, SDR cap screws torqued to spec, 20 ft-lbs,
(lubricated) or 25 ft-lbs (dry).
SEAL DISC INSTALLATION
Fasten seal disc to top of hub with four (4) 3/8” cap screws,
placing flat washers between seal disc and lock washer (See
Figure 8). Tighten to recommended standard of 15 ft-lb
(lubricated) or 20 ft-lb (dry).
CHECKING TIP CLEARANCE
Rotate fan in position inside fan ring or fan stack to check tip
clearance (See Figure 9). The recommended tip clearance is
between 1/2” and 1”. Check for spots where fan blade clear-
ance is not within the recommended tolerance.
Fan Diameter (ft) Minimum Maximum
6’ through 9’ 1/4” 1/2”
>9’ through 11’ 1/4” 5/8”
>11’ through 14’ 1/4” 3/4”
TIP CLEARANCE
Figure 8
Figure 9

Installation Manual 3000B Page 7 of 9 May 2012
If necessary adjust fan ring or fan stack by shimming to obtain
proper clearance. For heat exchangers, spacers may be added at
the fan ring joints to increase clearance (See Figure 10). Use a
chisel to maintain the correct gap until the bolts on the ring are re-
tightened.
Figure 10
If a small adjustment is needed, tighten or loosen nut on fan strut
in section requiring adjustment (See Figure 11).
Figure 11
SPACERS
OPERATING INSTRUCTIONS
Start fan and check rotation. Viewed from top (discharge), fan
blades should rotate clockwise.
Check motor power consumption to be sure fan is pulling d
desired load. CAUTION: If positive pitch is set in summer to
use all available motor amps (nameplate rating), motor could
be overloaded in winter. Design pitch angles usually do not use
all of the available motor horsepower. This ensures that the
motors will not be overloaded at low winter temperatures.
