V" Belt Tension - Progressive Turf Equipment SDR-90 Operators Manual And Parts Lists

"V" BELT TENSION:

Proper belt tensioning is a fundamental factor in the 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. Therefore, to ensure proper belt tension, 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 4.9 lbs. to a maximum
of 7.3 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.
