h.
Torque converter connects engine and transmis-
sion. This connection between engine and trans-
mission is a hydraulic connection. There is no
direct connection between engine and transmis-
sion. Torque converter transfers mechanical
energy from engine to transmission.

Transmission Oil Filter.
a.
Oil filter is mounted on frame on left side of
machine. Externally mounted oil filter has a
bypass valve. If there is a restriction in oil filter
or if oil viscosity is very high, filter housing
bypass valve will open.
b.
If inlet pressure to oil filter is 50 1.7 psi (345
12 kPa) greater than outlet pressure, bypass
valve will open. When oil does not go through
filter element, debris in oil will cause damage to
other hydraulic system components.
c.
Correct maintenance procedures must be fol-
lowed to ensure that element does not become
427-B1665
full of debris. Debris could stop oil flow to
hydraulic system.
