5.6.12 Pulling out High-stage Rotor
The 2016**C uses the 160SU, MU or LU as the high-stage rotor.
5.6.12.1 Disassembly
a) The upper side rotor comes off during disassembly of the suction cover. So it can be pulled out
easily. Either the M rotor or F rotor may be removed first. However, as the M rotor is longer, it is
easier to remove the M rotor first.
While holding and slightly lifting the shaft, pull out the rotor while rotating it clockwise. When
approximately two thirds of the rotor has been pulled out, draw the rest out slowly while attaching
the other hand to the outer circumference of the rotor.
If you pull out the M rotor without rotating it, the F rotor will also be pulled out
simultaneously.

b) Do not place the pulled-out rotor directly on the floor. Cover the floor with wooden pieces or the like
as a cushion. Otherwise, rest the bearing portion on a V block made of square timber to add a small
amount of lift.
c) Pull out the F rotor in the same way. Take care not to get the main bearing damaged with the edge
of rotor shaft during removal.
