Application Information

Proper belt alignment and belt tension will prevent premature bearing failure in the clutch and/or the pump. Use a straight edge held on the faces of the pulleys to check alignment. To provide proper belt tension, lay the straight edge on the tops of both pulleys as shown. Use mild force to deflect the belt as shown. Use a ruler to measure the amount of deflection. Proper tension will allow 1/2”  (1 cm) of deflection for each 12” (30 cm) of distance between the pulleys.

For example: If the distance between the pulleys is 3’ (90 cm), the deflection should be 1-1/2” (3 cm).
