“V” BELT ADJUSTMENT:
Begin by loosening 4 bolts at the base of the gearbox. Adjusting long
threaded bolt slides the gearbox back, tightening belt. After proper tension is
achieved, tighten 4 bolts at base of gearbox. You may have to place a ½” nut under
the head of the long threaded bolt to increase your adjustment length.
When changing belts, removal of grease fitting from the top of the center
spindle will make installation easier. Be sure belts run in proper groove.
“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.
CHECKING BELT TENSION
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.
