Note:
When MYK-A type flange is used as discharge flange for sideways discharge type
compressor, the length of the fastening bolt [97] is longer than other type models
due to using the discharge flange spacer [235].
Pay particular attention to the tightening the thrust bearing gland so that they are not
partially tightened.
Tighten with the procedure shown in 7.3.4.
