Figure 47: Thrust cover removal

Loosen and remove the Thrust Cover Frame Hex Cap Screws (370N) and remove the coupling
guard support (234A).

Gently pry the thrust bearing isolator (123A) and the thrust end cover (109A) out of the bearing
frame (228).

Remove and discard the thrust-bearing end-cover shims (390C).

Remove the two oil ring retainers and the oil ring inspection plugs from the top of the bearing frame.
