SAFETY INSTRUCTIONS
1. Always use qualied electrical and mechanical personnel for installation and maintenance of Republic
blowers and motors.
2. Disconnect the electrical power at the motor starter, fuse box or circuit breaker before working on the
system. Take special precautions to make sure the power cannot be turned on while you are working on the
blower. Use an approved Lock Out/Tag Out system.
3. Make sure the motor is electrically grounded, the mounting bolts are properly secured, and all guards are
in place before start-up.
4. Wear safety glasses and earplugs when working on the blower, air knife or discharge nozzles within a
Republic Blower System.
5. Do not operate blower/motor assembly with the belt guard removed. Make sure to install the inlet air lter
or piping to blower inlet, before starting the blower/motor.
6. Do not operate blower with the outlet open to atmosphere. Connect system piping or buttery valve to
prevent overloading the motor. Check the nal installation for proper amp loads.
7. Keep all tools, loose clothing and hands away from rotating or moving parts while the unit is running.
Never run the blower unit without the belt guard installed.
8. Inspect the blower at regular intervals for damaged or worn parts. REPLACE DAMAGED PARTS
IMMEDIATELY. DO NOT CONNECT OR TURN ON A DAMAGED BLOWER.
9. Inspect the inlet air lter at regular intervals and replace when necessary. A dirty air lter can cause
improper blower performance.
10. Use only genuine Republic Manufacturing brand replacement parts.

DRIVE BELT INFORMATION
Republic utilizes a 16-groove belt on all its centrifugal blowers and has the part number stamped on the at
side of the belt. Republic recommends that you keep spare belts in stock. It is also recommended that replace-
ment belts be purchased from a Republic distributor, to ensure that belt quality and blower performance are maintained.
Belts do vary from manufacturer to manufacturer, and all Republic belts are inspected for belt thickness and
imperfections prior to shipment.
BELT SIZING INFORMATION
Please nd the part number stamped on the face of the small stainless steel blower pulley, and then refer to the
following chart for the correct belt size.

BELT REMOVAL AND INSTALLATION

plies for the RB2400 model with one exception– there
are two (2) belts.
NOTE:
Tension Block rotated
counterclockwise (CCW)
(Tension Pulley removed
for clarity)
In order to remove or replace the Belt, the Tension
Block Assembly must be rotated out of the way to
allow for the Tension Arm to swing (CW). Loosen
the 5/16-18 SHCS as shown in Figure 1, the screw is
located on the backside of the Mounting Plate. Use a
1/4” allen wrench (not shown) on the 5/16-18 SHCS.
FIGURE 2
Once the 5/16-18 SHCS is removed, rotate the Tension
Block (CCW) to allow for the Tension Arm to swing
(CW) as shown in Detail B.

place and the wrench is removed, verify that the Belt is seated into all the grooves on both pulleys by manually
rotating the Motor Pulley (large pulley), and checking the alignment of the Belt on the groves.

e Tension Block is not to be used for tensioning the belt. e purpose of the Tension
Block is to help control the Tension Arm “backlash” on motors with high starting torque.
NOTE:
Using a at blade screwdriver, adjust the
slotted 5/16-18 SS Hex Head screw on
the Tension Block until the Hex Head
just touches the Rubber Block on the
Tension Arm assembly. Tighten jam nut
with a 1/4” wrench and reinstall the belt

e hex head screw is not designed to put additional pressure on the Tension Arm or Belt, it is intended to pre-
vent the backward movement of high torque motors.

SPRING REPLACEMENT INSTALLATION
Important–Replace spring when replacing belt to insure proper tension on you new belt.
1. Remove spring from 1/4 shoulder bolt on blower mounting plate.
2. Remove the tension pulley assemply from mounting plate by removing pivot pin (Item 11).
3. Remove the tension pulley sha (Item 3). THis sha has le-handed threads, so you will need to turn
clockwise to loosen. Items 4, 5, 6, 13, and 14 will remain attached to Item 3.
4. Remove shoulder bolt (Item 12).
5. Replace spring and reinstall shoulder bolt (Item 12).
6. Reinstall tension pulley assembly to mounting plate by tightening pivot pin (Item 11). Use Loctite 242
(removable strength) and torque to 25 /lbs.
7. Apply Loctite 242 (removable strength) to tension pulley sha threads (Item 3) and install to tension arm
(Item 2). Twist tension pulley sha counterclockwise to tighten.
8. Reinstall spring to 1/4 shoulder bolt on blower back plate.

e RB2400 model comes equipped with two (2) blower heads and may require a combination of Tension
Pulley Assemblies. When looking at the belt side or the belt guard side of this blower, the le side head is
called and engraved with the letters “H1” and the right side head is called and engraved with the letters “H2”.
e center distance of the motor pulley and blower pulley sha on the “H1” side is slightly shorter than the
“H2” side.
In order for the proper belt sizes to function on this blower, the combination of 4” and 5” Tension Pulley
assemblies were incorporated. Use the chart below to nd which Tension Pulley is required on either the
“H1” side or “H2” side of the blower.

- When installing a new motor pulley or servicing your existing unit, make sure that the outer grooves on
both the motor pulley and blower pulley are not damaged, nicked or dinged.
- Damaged pulley grooves can cause premature belt failures or higher than normal levels of vibration.
- Be sure to use a Torque wrench when installing the Motor Pulley.
- Torque the set screws to 36 ./lbs. or 430 in./lbs.
- Torque the set screws evenly to ensure proper alignment.

When installing a new motor pulley or servicing your existing unit, verify the outer grooves on both the motor
pulley and blower pulley are not damaged, nicked or dinged. Damaged pulley grooves can cause premature
belt failures or higher than normal levels of vibration. Be sure to use a torque wrench when installing the motor
pulley. Torque the setscrews to 36 ./lb. or 430 in./lb. Torque the setscrews evenly to ensure proper alignment.
