Assembly
1.
Slide the screen shaft (10), with the drive end to the drive side, into the shaft housing (2).
2.
Install the inner seals (11) into the bearing housings (6). Tap the bearings (12) into the bearing housing (6). Slide
this assembly onto the shaft (10). Insert the bearing housing (6) into the screen side plate (1) and use the bolts in
the bearing housing flange to draw the housing into the screen frame (1) and the shaft housing (2). Tighten the
bolts evenly around the flange to prevent the housing (6) from jamming as it is installed. When the bearing
housing (6) is all the way in, torque the bolts in the flange. Repeat for the opposite side.
3.
Install the seal (13) into the seal retainer plate (14). The retainer plate (14) can be bolted into place.
4.
Connect the grease lines (16) to the seal retainer plate (14).
