INTRODUCTION
YOUR KEY TO TROUBLE FREE SERVICE
Thank you for investing in Sutorbilt quality. The Sutorbuilt reputation for rugged dependability has been earned
by over 50 years of service in demanding, industrial operations where downtime cannot be tolerated and efficient
blower performance is expected.
Your Sutorbilt blower is a precision engineered blower that has been carefully manufactured and thoroughly
tested at the state-of the art Gardner Denver Blower Factory in Sedalia, Missouri.
As with other precision machinery, there are several relatively simple installation, operation and maintenance
procedures that you must observe to assure optimum blower performance. There is no guesswork in the
manufacture of your highly advanced Sutorbilt blower and there must be none in preparing the blower to get the
job done in the field.
The purpose of this manual is to help you properly install, operate and maintain your Sutorbilt blower. It is
essential that you review all sections of this manual in preparation for installing your blower. Follow the
instructions for installing your blower. Follow the instructions carefully and you will be rewarded with trouble-free
Sutorbilt service year in and year out.

SECTION 1
EQUIPMENT CHECK
Before uncrating, check the packing slip carefully to
be sure all the parts have been received. All
accessories are listed as separate items on the
packing slip, and small important accessories such
as relief valves can be overlooked or lost. After
every item on the packing slip has been checked off,
uncrate carefully. Register a claim with the carrier
for lost or damaged equipment.
Customers are cautioned to provide
adequate protection, warning and safety
equipment necessary to protect personnel
against hazards involved in installation and
operation of this equipment in the system or
facility.
STORAGE
Your Gardner Denver Blower was packaged at the
factory with adequate protection to permit normal
storage for up to six (6) months.
If the unit is to be stored under adverse conditions or
for extended periods of time, the following additional
measures should be taken to prevent damage.
1. Store the blower in a clean, dry, heated (if
possible) area.
2. Make certain inlet and discharge air ports are
tightly covered to prevent foreign material from
entering the air box.
3. All exposed, non-painted surfaces should be
protected against rust and corrosion.
4. Provide adequate protection to avoid
accidental mechanical damage.
5. In high humidity or corrosive environments,
additional measures may be required to prevent
rusting of the blower internal surfaces.
6. To prevent rusting of gears, bearings, etc., the oil
reservoirs may be filled with normal operating oil.
7. Rotate the blower shaft (10 to 25 turns) weekly
during storage. Inspect the blower shaft (near the
shaft seal area) monthly and spray with rust inhibitor
if needed.
8. For long term storage (over six (6) months),
contact Gardner Denver Compressor Division
Customer Service for recommendations.
REMOVING PROTECTIVE MATERIALS
The shaft extension is protected with rust inhibitor
which can be removed with any standard solvent.
manufacturer.
Blower inlet and outlet are temporarily capped to
keep out dirt and other contaminants during
shipment. These covers must be removed before
start-up.
The internal surfaces of all Sutorbilt units are mist
sprayed with a rust preventative to protect the
machine during shipment. Remove this film upon
initial startup, using any commercial safety solvent.
Position the blower so that the inlet and discharge
connections are in the vertical position (vertical
airflow). On vertically mounted units, it will be
necessary to lay the unit on its side supporting the
ends of the unit so as not to restrict the port on the
bottom side. Place a shallow pan on the under side
of the unit. With the blower disconnected from
power, spray the solvent in the top port, rotating the
impellers by spinning the shaft manually. Continue
this procedure until the unit is visibly clean.
Rotating components will cause severe
injury in case of personal contact. Keep
hands and loose clothing away from blower
inlet and discharge ports..
replace to the proper operating level with clean,
fresh lubricant.

SECTION 2
INSTALLATION
LOCATION
Install the blower in a well lit, clean dry place with
plenty of room for inspection and maintenance.
FOUNDATIONS
For permanent installation we recommend concrete
foundations be provided, and the equipment should
be grouted to the concrete. It is necessary that a
suitable base be used, such as a steel combination
base under blower and motor, or a separate sole
plate under each. Before grouting, equipment must
be leveled, free of all stains, and anchored so no
movement will occur during setting of grout. After
grout has completely hardened, a recheck is
necessary to compensate for shrinkage, etc. If
required, add shims under blower feet after final
tightening of foundation anchor bolts to remove
strain from the blower housing.
Where jack screws or wedges are used during
grouting, they must be backed off and wedges
removed before final tightening of anchor bolts.
Refer to grouting instructions.
Where a concrete foundation is not feasible, care
must be taken to insure that equipment is firmly
anchored to adequate structural members,
restricting movement and vibration.
MOUNTING CONFIGURATIONS
The blower flex-mount design enables horizontal
and vertical mounting configurations with top or
bottom hand, right or left hand shaft positioning.
The units are center timed allowing rotation in either
direction (refer to Figure 2-1). If converting a blower
from vertical to horizontal, or horizontal to vertical
mounting configuration, additional mounting feet will
be required.
REPOSITIONING THE MOUNTING FEET.
1. Position the mounting feet to the desired
location and snug the capscrew.
2. Place the blower on its feet on a flat surface.
3. Loosen mounting feet capscrews and level unit
up. The bench or blower base flatness should be
within .002 of an inch.
If the unit is not flat within .002 of an inch, it
will be necessary to shim the blower feet at
installation.

Over tightening belts leads to heavy bearing
loads and premature failure.
NOTICE When changing mounting configuration, it
may be necessary to reposition vent plug (B), and
drain plug (A). Refer to Figure 3-1, page 17, for
correct location.
DRIVE INSTALLATION
When selecting a V-belt drive, check to be sure the
shaft overhung load limitation is not exceeded. Refer to
FIGURE 2- 2
, page 13, for overhung load calculations
and limitations.
Belt drives must be carefully aligned. Motor and blower
pulleys must be parallel to each other and in the same
plane within 1/32 inch. Belt tension should be carefully
adjusted to the belt manufacturer’s recommendation
using a belt tension gauge. Check tension frequently
during the first day of operation.
Over tightening belts leads to heavy bearing
loads and premature failure.
On the direct connected units, alignment and lubrication
of couplings to specifications of the coupling
manufacturer is very important. When mounted drives
are supplied from the factory proper alignment has
been established before shipment. However, during
shipping, handling and installation, it is likely that the
alignment has been disturbed and final adjustment
must be made before startup.
Exceeding overhung load limitations leads
to unwarrantable premature bearing failure
and shaft breakage.
The location of the sheave on the blower shaft greatly
affects the stress in the shaft. The optimum blower
sheave positioning is as close as possible to the blower
drive cover, not to exceed dimension “C” in Drive Shaft
Illustration, FIGURE 2- 2, page 13
The calculated shaft moment must not exceed the
maximum allowable moment listed in Maximum
Allowable Moment Chart, FIGURE 2- 2 page 13. If the
calculated shaft moment exceed the maximum
allowable moment:
· Increase Sheave Diameters to Reduce Belt Pull
· Use Jackshaft Drive
· Use Direct Coupled or Gearbox Drive
To calculate shaft moment for a given V-Belt Drive
Arrangement:
1. Use the formula for Calculation of Belt Pull,
FIGURE 2- 2, page 13, to calculate belt pull. Refer
to Arc of Contact Factor Chart, Figure 2-2, page 15.
2. Insert the calculated belt pull into the formula for
Calculation of Shaft Moment, FIGURE 2- 2,
page 13 to arrive at the calculated shaft moment.
PIPING
Inlet and discharge connections on all blowers are large
enough to handle maximum volume with minimum
friction loss. Reducing the pipe diameter on either inlet
or discharge will only create additional line loss and
increase the overall pressure differential.
Excessive weight of piping and fittings will cause
internal misalignment and premature wear. Never allow
the blower to carry the weight of the pipe. If possible, a
spool or sleeve-type expansion joint should be installed
between the unit and the piping. Where a flexible
connection is not practical, the weight of the rigid
connection must be separately supported.
All system piping must be cleaned internally before
connecting to the blower.
factory. Do not attempt to operate the
blower before following proper lubrication
instructions. Permanent damage to the
gears, bearings and seals will occur.

LUBRICATION
FIGURE3- 1 - LUBRICATION
At the gear end the timing gear teeth are lubricated by being partially submerged in oil. The gear teeth serve as
oil slingers for gear end bearings. At the drive end the bearings are grease lubricated.
FILLING PROCEDURE
Refer to Figure 3-1. Remove the breather (B) from the gear cover. Add oil to the gear case until it reaches the
center line of the oil level gauge (H). Secure breather (B) in its correct location.
LUBRICATION SERVICE
Add fresh oil as required to maintain proper level. The oil should be drained, flushed and replaced every 1500
hours or more frequently if inspection so indicates. The oil drain plug is located at (A).
Do not overfill as this will tend to cause excessive heating of the gears and may damage the unit.
Bearings on the drive end of the blower require grease lubrication every 500 hours of operation. Lubricate the
bearings through grease fitting located at (C). When regreasing, the old grease will be forced out of the vents (E).
To prevent damage to seals, these vents must be open at all times.
AIR FILTERS AND FILTER SILENCERS
Servicing the air filters is one of the most important maintenance operations to be preformed to
insure long blower life.
Servicing frequency of filter elements is not time predictable. A differential pressure indicator, with a continuous
gauge reading, should be installed across the inlet filter. It will tell how much of the service life of the filter
element has been used. It will also eliminate both premature filter servicing and premature blower failure due to a
plugged filter when the filter pressure drop is used to establish maintenance points. In all cases refer to the filter
manufacturer’s service instructions. Due to the many types of filters, it is not practical to give specific instructions
covering all models.
NOTICE
Do not overfill as this will tend to cause excessive heating of the gears and may damage the unit.

SECTION 4
OPERATION
Future operating problems can be avoided if proper precautions are observed when the equipment is first put into
service.
Before starting under power, the blower should be turned over by hand to make certain there is not binding or
internal contact.
Each size blower has limits on pressure differential, running speed and discharge temperature which must not be
exceeded. These limits are shown in “Maximum Operating Limitations”, FIGURE 4- 1, below.
Operating beyond the specified operating limitations will result in damage to the unit.
It is important that the pressures and temperatures are measured directly at the ports of the blower to avoid error
that may be caused by intervening pipe runs, fittings, etc.
Relief valves must be used to protect against excessive pressure or vacuum conditions. These valves should be
tested at initial startup to be sure they are adjusted to relieve at or below the maximum pressure differential rating
of the blower.
NOTICE
Relief valves should be placed as close as possible to the blower inlet or discharge.
In some instances, pressure may be relieved at a lower point than the blower maximum in order to protect the
motor or the equipment served by the blower.
Discharge temperature switches are recommended to protect against excessive inlet restriction or inlet
temperatures. Check valves in the discharge line on pressure blowers and in the inlet line on vacuum blowers are
recommended to protect the blower from motoring backwards when shut down under load.

BLOWER STARTUP CHECKLIST
This startup procedure should be followed during the initial installation and after any shutdown periods or after the
blower has been worked on or moved to new location. It is suggested that the steps be followed in sequence and
checked off (√) in the boxes provided.
1. Check the unit and all piping for foreign material and clean if required.
2. Check the flatness of the feet and the alignment of the drive. Feet that are bolted down in a bind
can cause housing distortion and internal rubbing. Misaligned V-drives can cause the rotors to
rub against the headplates and cause a reduction in the volumetric efficiency of the unit.
Misaligned couplings can ruin bearings.
3. If the blower is V-belt driven, check the belt tension and alignment. Over-tensioned belts create
heavy bearing/shaft loads which lead to premature failure.
4. Be sure adequate drive guards are in place to protect the operator from severe personal injury
and incidental contact.
5. Check the unit for proper lubrication. Proper oil level cannot be over-emphasized. Too little oil
will ruin bearings and gears. Too much oil will cause overheating and can ruin gears and cause
other damage. Insure that grease lubricated bearings are properly lubricated.
6. With motor electrical power locked out and disconnected, turn the drive shaft by hand to be
certain the impellers do not bind.
7. “Jog” the unit with the motor a few times to check that rotation is in the proper direction, and to be
certain it turns freely and smoothly.
8. The internal surfaces of all Sutorbilt units are mist sprayed with a rust preventive to protect the
machine during the shipping and installation period. This film should be removed upon initial
startup.
9. Start the unit and operate 15 minutes at no load. During this time, check for hot spots and other
indications of interference.
10. Apply the load and observe the operation of the unit for one hour. Check frequently during the
first day of operation.
11. If malfunctions occur, do not continue to operate. Problems such as knocking rotors can cause
serious damage if the unit is operated without correction.
SB-7-622 Page 16

ASSEMBLY INSTRUCTIONS
NOTICE
1. Make sure all metallic parts are clean and free of any nicks or burrs.
2. Lubricate the outside diameter of the lip seal (15) with a light oil or grease. Install seals in both the drive
headplate (24) and gear headplate (18). The seal lip should always face towards the bearing or lubricant. New
seals should be installed each time the headplate is removed.
NOTICE
MECHANICAL SEALS ONLY
Make sure seals are fully seated. Use extreme care when installing.
A. Lightly coat the headplate bores with assembly lubricant.
B. Refer to Figure 7-1. Install mechanical seal (A) into the headplate bore (C) using a press and the
correct driver shown on page 24. Drive the seal securely on to its seat.
Use extreme care when installing seals in the headplate bores. Do not attempt to install the
mechanical seals without the use of a press. Blows from a hammer or mallet can damage the fragile
seal surface. Too much force can crush the seal casing. Make certain the seal is properly seated and
undamaged before proceeding.

FIGURE 7- 2
FIGURE 7- 3
3. Assemble gear headplate (18) and mounting foot (17) to the impeller case with cap screws (21) and where the
mounting foot is secured to the headplate use capscrews (16). The two positioning dowel pins (19) will ensure
proper alignment of the headplate and impeller case. Also secure lifting lugs using capscrews (21) (see exploded
assembly drawing on page 35. Refer to Figure 7-8, page 34, for torque specifications.
4. Apply a light oil or grease on the shaft seal areas and the bearing areas. Insert impellers into the gear headplate
using the same headplate bores as used in the original assembly.
Seals are delicate; use extreme care when installing impeller shafts in the headplate bores. A piece
of light shim stock wrapped around the shaft keyway will prevent cutting the seal lip.
5. Position blower so that impellers are vertical, with the drive end on top. It will be necessary to use blocks in order
for the unit to set level. Measure the total end clearance using a depth micrometer (see Figure 7-2).
If total clearance is not within the limits specified in Figure 7-4, page 30, it may be necessary to shim the case to
obtain the proper total end clearance. The shim should be placed between the drive headplate and impeller
case.
NOTICE
6. Assemble drive headplate (24) to impeller case as in step 3 with the gear headplate. If shims were required,
place shims between drive headplate and impeller case.
7. Insert bearing-seal spacers (34), (41) into the drive shaft headplate bore and spacer (33) into the remaining bores
(see exploded view, page 35).
MECHANICAL SEALS ONLY
A. Refer to Figure 7-1, page 28. Lightly coat the impeller shaft (H) and the inside diameter of the mating ring (B) with
assembly lubricant.
B. Install the mating ring (B) on the shaft only far enough to install spacer (34), (41) in the bore and allow for the
bearing inner race (E) to be started on the shaft.
SB-7-622 Page 26

11. Impeller should now be checked for free axial movement by hitting the ends of the impeller shafts with the
palm of your hand.
12. Push the impellers against the gear headplate and recheck the total end clearance between the drive
headplate and the impellers (see FIGURE 7-4, page 31).
A. If total end clearance is insufficient, loosen impeller case to headplate bolts on either headplate, and
move the headplate away from the case far enough to insert a paper shim in the amount equal to the
insufficient clearance. Retighten case bolts and again check the total end clearance. Refer to FIGURE 7-4,
page 31, for correct clearance.
B. Excessive end clearances normally will require new impeller assemblies, but in some circumstances the
impeller case can be removed and reduced in width by machining off the amount of excess clearance.
blower may turn freely by hand when cold, under operating conditions, the parts expand, and the
rotors are subject to slight deflection.
If the clearances are not sufficient the impellers may contact each other or the housing with
destructive results. If the clearances are too great, the blower may not develop the pressure or
airflow that is required to perform its function.
FIGURE 7- 5
13. Impeller tip to case clearance should be checked at this time by inserting the correct thickness feeler gauge
between the tip and the case (B) and rotating the impeller (see Figure 7-4, page 31). Repeat the procedure on
both impellers.
NOTICE
impeller to ensure that the tips do not bind along their length.
14. Replace the drive shaft grease seal (31) in the drive end cover (29). The seal lip should always face toward
the bearing or lubricant. Pack the bearing cavities with the recommended grease.
15. Secure drive cover (29) and wavy spring (28) to drive headplate using capscrews (30). Refer to Figure 7-8,
page 36, for torque specifications.
NOTICE
SB-7-622 Page 28
16 SETTING IMPELLER END CLEARANCE
Refer to Figure 7-1, page 29. The gear end bearings are held in position by the force created by the wavy spring
(28) on the drive end and the bearing retainer (12) on the gear end. The interference fit between the shaft (H) and the
bearing inner race (E) keeps the shaft from moving axially.
End clearance adjustment of both impellers is controlled by adjustment of the bearing retainer (12). Tightening the
bearing retainer screws (10) moves the bearing to load the wavy spring (28), and the impeller is forced toward the drive
end. Relaxing the screws allows the wavy spring to return the impeller toward the gear end.
A. With impellers tight against the gear headplate, measure the distance (A) from the bearing outer race to the
gear headplate using a depth micrometer (see Figure 7-5, page 32).
B. Subtract 1/3 of the total end clearance from the value measured at point (A). This value is the amount of shim
(13) that should be placed between the retainer and the headplate at point (S).
C. Secure bearing retainer (12) with the correct amount of shim, to the headplate using capscrews (10). Torque
capscrews to the specifications given in Figure 7-7, page 34.
D. Recheck end clearances. Approximately 1/3 of the total end clearance should be on the gear end and the
remaining 2/3 on the drive end (refer to Figure 7-4, page 31).
If clearances require adjusting, loosen the bearing retainer capscrews (10) and insert shims to move the
impeller closer to the gear headplate and remove shims to move the impellers away from the gear headplate.
FIGURE 7- 6
17. INSTALLING THE TIMING GEARS
Impellers are held in time by gears which are taper pinned and bolted to a timing hub, which in turn is pressed and
taper pinned onto the shaft. The timing gears can be rotated in relation to the hub by removing the taper pins in the
web on the gear and loosening the capscrews. Because the capscrews are oversized, the gear will rotate – within limits
– relative to the timing hub when the screws are loosened.
A. Apply a light grease, or oil, on the shaft area where the timing gear will be positioned.
B. Lubricate the inside diameter of spacers (32) with assembly lubricant and install on the gear end shafts.
C. Using a piece of paper large enough to cover the open end of the gear headplate, trace the shafts on the
paper and cut-out shaft holes. This will be placed on the shafts before the gears to protect the bearings from
metal shavings when drilling taper pin holes in the following procedure.
D. Place feeler stock in the amount of 1/3 of the total end clearance between drive headplate and both impellers.
This will stop the impellers from contacting the headplate while the gears are being driven on.
If installing gears on a blower containing mechanical seals, a press must be used to drive gears on
the shafts. Blows from a hammer or mallet will damage the seal..
E.
If reusing the timing gears and hubs, they should be returned to their original position with respect to the
If replacement gears are used, secure each gear (9) to its timing hub (39) with capscrews (38) and lockwasher
impellers.
(37) and tighten slightly.
SB-7-622 Page 29
Replacement gears have minimum backlash marks on the outside diameter of the gear face.
Utilize a press whenever possible when installing gears
.
If any of the four gear backlash readings are not
within the specified limits, the gears must be
Be careful not to allow cuttings to drop behind
the gears and contaminate the bearings.
NOTICE
These marks should be located 180 degrees from each other (see Figure 7-6)..
F. Position impellers so they are 90 degrees to each other. Using the driving tool shown on page 22, install the
gears and hubs on the shafts using the taper pin holes and match marks for correct positioning. Check to be sure
impellers are in correct position as previously match marked.
NOTICE
G. Refer to diagram in Figure 7-4, page 31. Use feeler gauges to check clearances between impeller lobes at
A-A and C-C. Add the clearances, and divide the total clearance evenly between A-A and C-C.
H. Loosen the four capscrews (38) in one gear only. Wedge the correct amount of feeler gauge between
impeller at A-A. If movement between the gear and hub is not sufficient to time the impellers, it will be necessary
to loosen the four capscrews (38) in the mating gear to obtain a large adjustment range. Adjust so that the
clearance at A-A is equal to C-C within .001 inch.
Clearances must be checked on both sides of each impeller lobe over the entire length. This procedure may
require repeating several times until impeller lobe clearance is equal on both sides.
I. Secure the timing gears (9) to hubs (39) with capscrews (38) and lockwasher (37). Tighten capscrews to the
torque specification listed in Figure 7-6, page 35.
J. Check gear backlash four places at 90 degree intervals as described in the disassembly procedure (Item 4).
NOTICE
replaced.
K. Reream taper pin hole between the shaft and hub with a hand reamer and replace taper pin (8) if movement
between the shaft and hub (39) was negligible. If rereaming fails to eliminate edges due to slight misalignment,
drill and ream a new hole approximately 90 degrees from the original hole. Control the depth of the taper pin,
leaving approximately 1/8” taper pin protruding beyond the hub and shaft.
L. Reream center drilled hole in the hub and gear web. If rereaming fails to eliminate edges set up by retiming,
ream hole for the next larger taper pin or drill and ream a new hole approximately 90 degrees from the original
hole. Control the depth of the threaded taper pin (36), leaving the threaded portion of the pin protruded beyond
the hub.
Replacement gears are not drilled for taper pin (8). These holes must be drilled and reamed after the gears
are in proper position and the unit retimed.
NOTICE
M. Remove paper from behind the gears. Make certain metal cuttings did not contaminate the bearings.
18 Assemble gear cover (3) and gasket (7) to the gear headplate (18) using capscrew (5). Tighten capscrews
alternately and evenly. Refer to Figure 7-6, page 35 for torque specifications.
19 Place blower on its feet on a flat surface. Loosen capscrews (16) and level unit up. The bench or blower
base flatness should be within .002 of an inch. Re-tighten capscrews (16) to the specifications in Figure 7-6,
