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.
