1 . General.
A.This procedure gives instructions to remove the No. 1 bearing assembly (01100). Refer to Figure 301.
B.This procedure starts with the propulsor assembly in the horizontal position, installed on pedestals or installed in the 11C3044   adapter assembly, attached to the customer overhead rail system.
NOTE:
The LPT module/fan mid shaft and fan booster assembly must be previously removed.
C.Make sure that the propulsor assembly and No. 1 bearing assembly have the correct support at all times to prevent injury to personnel or damage to engine parts.
D.Make sure that personnel wear gloves when they remove or touch seals and bearings. Dirt or oil from their fingers can damage the seals and bearing surfaces.
E.Put tags on the parts for special inspection if the No. 1 bearing assembly was operated in unusual conditions.
F.Make sure that personnel read this procedure and know the step-by-step instructions and special tool usage before they remove the No. 1 bearing assembly from the engine assembly.
