Leakage of mud and water into crankcase will be
indicated by a milky appearance of crankcase oil.
Rubber baffles are provided as standard equipment
to reduce the amount of abrasive fluid entering power
end and should be installed on all three (3) extension
rods.
Mud will also be seen below the oil stop heads on the
inside of crankcase through crosshead inspection
plate openings.
When mud is found in the crankcase, the oil and filter
should be changed.
Drain and clean out the crankcase before putting in
new oil. Replace the oil stop head seals before
running the pump.
We recommend oil stop head seals be changed
every six (6) months of operation, even though
leakage is not evident.
WARNING
Failure to properly reinstall and maintain
baffles voids the warranty as they are
designed to help prevent mud and other
contaminants from entering and
damaging the crankcase.
WARNING
When mud or other foreign material is
found in the crankcase, the oil must be
changed before operating the pump to
avoid damage to moving parts.
