Choose desired parallel adapter plate. Mount parallel adapter plate to motor flange using appropriate
mounting hardware. Note: Bolt can not stick past adapter plate. Note: The motor side of the plate is piloted for
the motor. The flat side goes against the shroud. Apply a few drops of Loctite # 242 to screw threads prior to
assembly.
Apply a few drops of loctite #609 to the motor shaft and loosely mount pulley #2 to motor shaft. Place
motor/plate assembly against shroud in the mounting position and measure the distance from the open
shroud face to the face of the pulley. The pulley recess distance should match the opposite side recorded
earlier. Readjust pulley until the distance is matched and then tighten clamp screw to 13 in-lbs. Note: Once
the #609 loctite is applied, this step should be completed within 10 minutes.
Place drive belt over pulley #1 (drive screw shaft).
Place motor assembly against shroud and place belt over Pulley #2.
Loosely mount desired motor using (4) button head screws (404XR) or (4) socket head cap screws (406XR),
Item # 515, and (4) spring washers, Item # 541. Note: Mounting holes are located inside mounting shroud.
Note: It is critical that the correct length bolts be used
.
Tension drive belt by applying approximately 15 pound of side force to the motor. Tighten the screws/bolts.
Run the table back and forth while observing the belt. The belt should be riding in the center of the pulley
surface (between the flanges). If the belt continues to run against one side of the pulley then the alignment
needs to be recalibrated. Mount the shroud cover and tighten (4) button head screws, item #539.
