Sheave alignment
• The motor sheave is to be positioned as close as possible to the motor
in order to minimize torque on the motor bushings.
• The motor and fan sheaves may have grooves that are not used. The
bottom surface of the motor and fan sheaves must be aligned within
1
⁄
8
" of each other and level within
1
⁄
2
° (
1
⁄
8
" in 12) in order to not adversely
affect belt and sheave life.
• Alignment can be achieved by placing a straight edge across the top
of the sheaves making sure that it is level and measuring down to the
bottom surface of both sheaves at four points.
• The belt is to be located in the lowest set of grooves.
