Normal Drain Period
NOTE: Normal drain periods and filter change intervals are
for average environmental and duty-cycle
conditions. Severe or sustained high operating
temperatures or very dusty atmospheric conditions
will cause accelerated deterioration and contam-
ination. For extreme conditions, judgment must be
used to determine the required change intervals.
8. Change oil filter element. Refer to Lubrication, page 9-1.
NOTE: It is recommended that filter elements be changed
after 50 and 100 hours of operation on new and
rebuilt or repaired units, then at normal intervals
thereafter.
a. Drain transmission and remove pump screen. Clean
screen thoroughly and reinstall it, using a new
gasket.
b. Remove and discard both filter elements. Clean

d. Run engine at 800 RPM to prime converter and
lines.
e. Recheck level with engine running at 800 RPM and
add oil to bring level to LOW mark. When oil
temperature is hot,180 to 200 °F (82 to 93 °C), make
final oil level check. Bring oil level to FULL mark.
