Oil Filter (Powertrain).
427-C1732
(1)
Powertrain oil filter is mounted on right side of machine frame under platform.
(2)
Externally mounted oil filter has a bypass valve. If there is a restriction in oil filter or if oil viscosity is
high, bypass valve in filter housing will open.
(3)
If inlet pressure to oil filter is 50 3 psi (345 21 kPa) greater than outlet pressure, bypass valve will
open. When oil does not flow through filter element, debris in oil could cause damage to other hydraulic
system components.
(4)
Correct maintenance recommendations must be followed to ensure element does not fill with debris. If ele-
ment is full of debris, flow of clean oil to hydraulic system stops.
