8.6 Dismantling and installing the turbine diffuser

and nozzle ring

CAUTION

Falling nozzle ring

The nozzle ring hangs only loosely on the positioning pins.

Before removing the turbine diffuser, secure the nozzle to prevent it
from falling.

Before disassembling the turbine diffuser, if possible secure the
nozzle ring against falling with a lashing strap and a wooden block.
