reciprocating compressor bearing wear

Hello everyone. i have read a article regarding to reciprocating compressor bearing wear but something i have don't understand !
The article stated that Temperature of the discharge valve above 350F ( 177°C ) the oil will start to break down, causing accelerated bear wear . The article did not mention whether want to change new compressor oil or remain using after we troubleshoot and solve the problem .Could anybody tell me what should i do when face this type of problem ! Any advice would be greatly appreciated .

When oil reach that temperature it becomes carbonized and smell. You could make oil acid test and check color of oil, and accordingly, change oil and fit burn out filter-dryer in suction and discharge pipe.
In fact, you should proceed like you heaved burn-out.

Hi Oilzee,
Might be an idea to send a sample away for analysis. They can tell you carbon content, acid levels, and presence of any wear metals ie bearing, valve, casting, piston rings etc.
I was told by a lubrication chemist that mineral life should be halved every 10c above 80c ie. That`s ok in theory but i`ve not meet a customer yet who`ll pay for that.

Glenn
