"V" BELT DRIVE

"V" BELT TENSION - 100h / Monthly
Proper belt tension is a fundamental factor in successful V-belt operation. Lack
of tension will cause slippage, and too much tension will cause excessive belt
stretch as well as damage to the drive components, such as bearings and shafts.
To assess the condition of the automatic tensioner, the following procedure is
recommended.
At the mid-point of the span, apply a deflection force with a spring scale in the
direction perpendicular to the span until the belt is deflected the 3/8".
The recommended force to deflect the belt is a minimum of 5 lbs. to a maximum
of 7 lbs.
The first 24 to 48 hours of operation is the belt "run in" period. To ensure
satisfactory belt performance, belt tension should be checked during this time
period.
"V" BELT ADJUSTMENT
All deck drive belts utilize an automatic rubber torsional tensioning device.
These tensioners are pre-set upon installation and require no further adjustment or
maintenance.
A tool is provided to allow easy release of
belt tension using a ½" square drive breaker
bar or rachet.
