TM 10-4320-307-24 3-7 FLEXIBLE COUPLING INSPECT/ALIGN/REPAIR/REPLACE(CONT). c. Install dial indicator and magnetic base (4) placing magnetic base on speed increaser side hub (2). NOTE The feeler position on the pump side hub (1) should be approximately on the coupling flange thickness center line. d. With dial gauge positioned at the top, zero the gauge. e. Rotate speed increaser half coupling slowly in operating direction. f. Record dial indicator readings at 0, 90, 180, 270, and 360 degrees. NOTE If LO is not equal to L360, the dial gage has moved or is in need of calibration. Replace if necessary and take another set of readings. The maximum difference between opposite headings (LO-L180 or L90- L270) corresponds to the L value or lateral misalignment. 3-15
