V-Belt
INSTALLATION GUIDE
INSPECT SHEAVES
The following sections outline installation procedures that will
ensure maximum life and performance for your V-belts.
Check sheaves for cleanliness, damage, and wear whether you are
replacing an existing belt, performing routine maintenance, or
installing a new drive.
An alternative method for checking for sheave groove wear is to
place a new belt in the sheave groove. Note that the top of the belt
should be fush with or slightly above the outer diameter of the
sheave. Remember that if the belt top is below the sheave’s outer
diameter, the groove is worn.
Perform further inspection if possible. Use the Groove Dimension
tables located on pages 4 and 5 of this manual to determine if
excessive wear has occurred or to select replacement belts and
sheave cross sections.
1 2 INSTALL HARDWARE
Always remember to select the correct sheave. Then, after
you make the correct selection, be sure to install the sheaves
correctly.
Before performing any installation, follow correct lockout
procedures to prevent any accidents.
IMPORTANT: Disconnect power supply to machine before doing
ANY work.
QD® Bushing
If the sheaves are made with a QD ® hub, follow these installation
and removal instructions.
HOW TO INSTALL A SHEAVE WITH A QD ® HUB
Insert the bushing in the hub and line up bolt holes.
Insert the pull-up bolts and turn until fnger tight.
Hold the loosely assembled unit so the bushing fange points
toward the shaft bearings. Reverse mounting the QD ® bushing
can be advantageous for some applications.
Slip the unit onto the shaft and align the hub in the desired
position.
Tighten the setscrew in the fange only enough to hold the
assembly in position.
Tighten each pull-up bolt alternately and evenly.
Recheck alignment and completely tighten the setscrew on the
shaft.
Use a stiff brush to remove rust and dirt. Use a soft cloth to wipe
off oil and grease. Select the proper sheave groove gauge and
template for the sheave diameter. Insert the gauge in the groove
and look for voids that indicate dishing or other uneven and
abnormal wear.
