hi there , I'm happy to tell you that I finally managed to finish this minor overhauling job. I did the following:
1- replaced the Journal bearing ( DE ) .
2- replaced the combined ( journal/thrust bearing) (NDE).
3- replaced the main oil pump ( MOP) which i discovered that it...
Maybe I did not mentioned the story behind all of this which I'm still digging it because i just joined this plant 1 month ago and I'm struggling to get history about this issue.
I found an investigation report said this :
on July 2018 ,The blower main oil pump had a major failure.

update :
the shaft is too heavy to push !!
we are dying to reach 0.45mm ( required axial float .
the location is too small you cannot fit your body and push.
i got 2 guys , one big strong Indian guy and another small Filipino guy ( who is also very good rotating machines guy ), but i need...
UPDATE:
we found the thrust bearing pads white metal melted away.
we are suspecting our main oil pump is having internal damage , looking to the oil pressure trends , the oil pressure dropped before the trip and the bearing temp , went to 110 degree C.
now we are stuck up after replacing the...
quick update :
axial float found 1.6mm
old info : bearing temp went to 119 deg. C during the trip .
also old info : lube oil pump pressure dropped to low level before the trip.
so we are assuming thrust bearing failure.( maybe the journal as well )
We are planning to open the bearings and...
Thank you so much for your support guys ! tomorrow we are going to drop the coupling & measure the axial float . I will tell you about the findings ,,,

The blower was offline for around 1.5 months for some low lube oil pressure then oil...
