“V” BELT ADJUSTMENT:
Begin by loosening 4 bolts at the base of the gearbox. By adjusting long
threaded bolt, this will slide the gearbox back, tightening the belt. After
proper tension is achieved, tighten 4 bolts at base of gearbox. You may
have to place a 1/2” 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 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.
