V-Belt Drives
V-belt drives must be checked on a regular basis
for wear, tension, alignment and dirt accumulation.
Premature or frequent belt failures can be caused by
improper belt tension —either too loose or too tight—
or misaligned sheaves. Abnormally high belt tension
or drive misalignment will cause excessive bearing
loads and may result in failure of the fan and/or motor
bearings. Conversely, loose belts will cause squealing
on start-up, excessive belt flutter, slippage, and
overheated sheaves. Either excessively loose or tight
belts may cause fan vibration.
When replacing V-belts on multiple groove drives all
belts should be changed to provide uniform drive
loading. Do not pry belts on or off the sheave. Loosen
belt tension until belts can be removed by simply
lifting the belts off the
sheaves. After replacing
belts, insure that slack in
each belt is on the same
side of the drive. Belt
dressing should never
be used.
Do not install new belts on worn sheaves. If the
sheaves have grooves worn in them, they must be
replaced before new belts are installed.
The proper tension for operating a V-belt drive is the
lowest tension at which the belts will not slip at peak
load conditions. Check belt tension before start up
and after the first 24 hours of operation. The belt
tension should also be checked periodically thereafter.

Unit Identification
This tag is an example of an identification label on the
fan. The information provides general details about the
fan, as well as containing specific information unique to
the unit. When contacting your Greenheck representative
with future needs or questions, please have the
information on this label available.
Tags are mounted on the drive frame in an area which
is clearly visible, usually near the fan outlet on the drive
side of the fan. The exact tag location may differ due fan
model and size.
