Verify Machine Mounting Dimensions
Verify proper fit of the motor to the machine mount by measuring the following
machine mounting dimensions.
1. Verify these dimensions are within the measurement range in the table:
• Pilot diameter
• Shaft diameter, small and large
• Shaft length, small and overall
2. Verify the Total Indicator Readout (TIR) of these dimensions is less than the
value in the table when measured with a dial indicator:
• Shaft runout
• Pilot concentricity
• Mounting surface perpendicularity
