Sticky Bearing
Sticky Bearing
(OP)
Hi guys.
We were trying to check a centrifugal compressor's gearbox for any degradation. I've noticed that the journal bearings of this gearbox became very sticky due to oil, also the internal components of the gearbox were all very sticky.
What is the cause for this stickiness? ?
Knowing that the compressor has a lubrication system and the condition of the oil wasn't bad (nor good).

I had a Renault with wet sleeves with a real small leak that let antifreeze/coolant into the oil.
After a batch of miles, some of the tappets would hang up and hold a few valves open until the engine warmed up a little.

@Abualnassr: chlorine is not a stuff that you would want in a lubricant. most lubricants would not be compatible with chlorine. i suggest you have the lubricant checked whether it has reacted with chlorine. if so, you will have to find out how it got there - which means you will have to check the bearing sealing system.
whatever the cause, you will have to clean out the mess thoroughly - and a careul check whether gears of the bearings of the gearbox for corrosive attack would be advisable.

since in your case the lubricant for the compressor bearings and the driving gearbox is the same, the sticky stuff has spread into the gearbox.

Thanks romke for putting it all together for me.
