Motor alignment is to check motor shaft coupling to pump or fan shaft coupling free rotation with axial and radial direction with the dial gauge clearance of all the 4 angles 0° , 90° , 180° , 270 below 0.05mm (50 microns). And also to check the coupling gap as per general arrangement drawing and also to check bearing clearance of both DE and NDE.
