EPLACEMENT
Refer to
. When compressor fluid
carryover is evident, after replacing or inspecting the
fluid return line strainer and orifice, the blowdown
valve and checking the oil; and all are in satisfactory
condition, the separator element must be replaced
with Kit number 250034-087 (element for air/fluid
separator).
1. Disconnect all sump cover piping connec-
tions to permit removal (return line, service
line, etc.).
2. Remove the fluid return line from the fitting
on the cover.
3. Remove the eight (8) cover bolts and wash-
ers and lift the cover off the sump.
4. Remove the separator element.
5. Scrape the old gasket material from the
cover and the flange on the sump. Do not
allow the scrapings to fall into the tank.
6. Install the new element.
7. Replace the sump cover and bolts. Lightly
tighten all the bolts and then gradually
tighten them alternating between bolts which
are diagonally opposite each other. Torque
the bolts to 160 ft-lbs (215 N•m).
8. Reconnect all piping. The fluid return line
tube should extend to the bottom of the sep-
arator element which will ensure proper
return line flow.
9. Clean the fluid return line strainer and clear
the orifice before starting the compressor.
10. After 24 hours of operation, tighten the sump
cover bolts to the value given in step 7.
