“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.
