Poly-V ® Belt
INSTALLATION GUIDE
INSTALLATION
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.
HOW TO REMOVE A SHEAVE WITH A QD ® HUB
Place two of the pull-up bolts in the tapped holes in the sheave.
Turn the bolts alternately and evenly. They will push against the
bushing fange and act as jackscrews to break the grip between
the bushing and the hub.

Split Taper Bushing
If the sheaves are made for split taper bushings, follow these
installation and removal instructions.
HOW TO INSTALL SPLIT TAPER BUSHING SHEAVES
Put the bushing loosely in the sheave and start the capscrews.
Place the assembly on the shaft. Align both edges of the sheave
with the edges of its mating sheave (i.e. the sheave on the
driven shaft).
Tighten the capscrews according to the instructions furnished with
the bushings.
HOW TO REMOVE SPLIT TAPER BUSHING SHEAVES
Remove all capscrews.
Put two of the capscrews in the tapped holes in the fange of the
bushing.
Turn the bolts alternately and evenly until the sheave has loosened.
Remove the sheave/fange assembly from the shaft.
