4.
Lift the element from the sump.
5.
Inspect and/or replace the elements if necessary - shine a light inside the element to reveal areas of
heavy dirt, varnish deposits or breaks (ruptures) in its media. Also inspect (sealing) o-ring in element
for damage. Before installing new or old element, apply (heavy) grease to sealing o-ring. Oil may
be wiped off by the holder and the o-ring could be damaged.
6.
Inspect oil scavenge orifice and strainer for fouling. Replace if necessary.
7.
Lower element into sump and press element down into holder. Do not use excessive force as
element damage may occur.
8.
Carefully place sump cover and o-ring seal on sump flange. Check that the adjustable space (e.g.,
pipe segment threaded under cover) makes contact with the top of the elements. The contact
(e.g.,1/32" interference typical) should be firm enough to provide a grounding path between the
elements and the vessel without crush-damaging the former's structure.
9.
After compressor is started and pressurized, inspect sump cover joint for leaks.
