“V” BELT DRIVE
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.
BELT ADJUSTMENT
All deck drive belts utilize an automatic rubber torsion tensioning
device. These tensioners are pre-set upon installation and require no
further adjustment or maintenance.
In normal service the tensioner arm angle (see detail at right) should
read between 30 degrees (new belt) and 15 degrees.
A tool is provided to allow easy release of belt tension using a ½”
drive breaker bar or ratchet.
