EX, SGX VIBRATOR MOTORS
9 - Orient eccentric weight(s) with split facing
junction box and pin on inside of weight
aligned with keyway of motor shaft. If two
weights are used, install heaviest weight
closest to bearing mount.
10 - Using a torque wrench and 6mm hex
bit, tighten M8 cap screw to 250 in. lbs.
11 - Check rotation and axial play of motor shaft as follows:
a. Manually rotate the eccentric weight both clockwise and counterclockwise, allowing weight to
fully rotate. If binding is felt, disassemble motor as necessary to determine cause of binding,
correct defect, and reassemble bearing in accordance with this procedure.
b. Using both hands, grip eccentric weight(s) and push and pull along axial centerline of motor
assembly. Shaft must have no more than 1/16”-1/8” (1.6-3.2 mm) of movement. If excessive
axial movement is found, disassemble motor as necessary to determine cause of problem,
correct defect, and re-assemble bearing in accordance with this procedure.
12 - Apply a small amount of grease to O-
ring groove between bearing housing and
bearing mount, and then carefully install O-
ring in groove.
DO NOT STRETCH O-RING DURING
INSTALLATION.
Position cover on motor case, and install six
M6-1.0 x 16 screws hand tight. Using a
torque wrench and a 5mm hex bit, tighten
