• Inspection point: Check that the bearings enter evenly in the frame; the bearing
should rest against the wall of the power frame. After this assembly, the shaft
must be able to rotate by hand; however, there is some resistance to make it
turn due to the action of the labyrinth seals.
15. To position the thrust cover at the power frame, first position the thrust o-ring in the cover.
Figure 8.17 Positioning the thrust o-ring in the cover.
16. Lubricate the internal diameter of the labyrinth seal. Lubricant supplied by isolator manufacturer or P-80
Rubber Lubricant Emulsion is recommended (grease is NOT recommended).
