Extreme care should be taken

Lift end (2) of shaft (1) slightly

to center shaft (1), then push

shaft (1) in to establish

clearance between power

turbine disc (3) and nozzle (4)

and to load No. 5 bearing (5).

B. Turn shaft (1), listen and eel

for rubbing or binding.

Does shaft turn smoothly with no

unusual noises?
