6. If piston (traction) pump, front wheel motors or rear axle motor was removed
from machine for service, fill housing through case drain with new hydraulic
oil before starting engine. This will ensure that internal components have
adequate lubrication during initial operation.
7. After disconnecting or replacing any hydraulic components, operate machine
functions slowly until air is out of system (see
(page 5–79)).
8. Check for hydraulic oil leaks. Shut off engine and correct leaks if necessary.
Check oil level in hydraulic reservoir and add correct oil if necessary.
