Installation Instructions
NOTE
Prior to installing, liberally apply a coating of grease to the shaft, top of the bearing, sides of the bottom
bearing plate and inside the bottom bearing plate (layer ¼" to ½" in thickness). Applying grease as
indicated will help protect against moisture and foreign matter penetrating the bearing area.
1.
Attach the bottom bearing, collar facing up, to the
lower end of the Roto (Figure 11) by sliding the
bottom bearing onto the mounting shaft
(Figure 11A).
