If you replace the whole chiller it will fix the problem too. Just because someone else replaced the check valve and filter and it fixed their problem, that doesn't mean it will fix yours or that the check valve was even the problem on their chiller.

Those shavings are manufacturing debris from the evaporator.

How to make the perfect "Half-Hitch" knot or any other boyscout knot in 3 easy steps...
1. Remove your meter leads from the meter and very carefully return them to their storage case or bag.
2. Wait 2 seconds
3. Very carefully remove your meter leads from their storage place and enjoy your new knot!
That comment is very interesting........
I know for a fact that one trane parts house did just that. They have called customers and offered factory service after we ordered parts. This was at an old job. I've heard similar stories about the trane that I'm near now but no personal experience.

Thnx in advance.
Sorry jayguy,forgot to post back about the check valve - when I pulled out the check valve,the valve was hanging bout 1/2 open once and a while when operated by hand,so I replaced it - with the new oil check valve,oil filter,return strainer cleaned, That compressor is quiet now and running like a champ - I really need to look into the other 3 compressors the customer has,but they are dragging their feet for some time now - they are probably waiting for an actual problem - then blame the problem on the contractor or the chiller - instead of actually maintaining the chiller.And I have warned them of the two chillers short cycling for the past 3 -4 years now - they have not listened - really sucks.
dont have the unloader O ring p#
