Motors ventilating tubes severe corrosion posed problems are:
After several deep-thinking days the author proposed the below given solutions:
Expanding the tubes without the end-shields in position in the first instance distorted the motor frame; hence the motor body necessary extensive repairs delayed the motor reassembly by a month and absent spare motor threatened long plant shutdowns (SDs).
Having learnt the lesson the hard way, the crew re-tubed with end shields in position, did not expand the tubes but just m-seal sealed the tubes to motor body joints as the author advised.
Implementing RCA solution Benefits are
