44 EATON 350 Series Dual Path Mobile Pumps E-PUPI-TS006-E September 2007
Start-UpProcedure
When initially starting a new or
a rebuilt transmission system, it
is extremely important that the
start-up procedure be followed.
It prevents the chance of dam-
aging the unit which might
occur if the system was not
properly purged of air before
start-up.
1. After the transmission com-
ponents have been properly
installed, fill the servo pump
housing at least half full with
filtered system oil. Connect
all hydraulic lines and check
to be sure they are tight.
2. Install and adjust all control
linkage.
3. Fill the reservoir with an
approved oil that has been fil-
tered through a 10 micron fil-
ter. Refer to Eaton Technical
Data sheet number 3-401
titled Hydraulic Fluid
Recommendations.
4. Gasoline or L.P. engines:
remove the coil wire and turn
the engine over for 15 sec-
onds. Diesel engines: shut
off the fuel flow to the injec-
tors and turn the engine over
for 15 seconds.
5. Replace the coil wire or
return the fuel flow to the
injectors. Place the transmis-
sion unit in the neutral posi-
tion, start the engine and run
it at a low idle. The charge
pump should immediately
pick up oil and fill the sys-
tem. If there is no indication
of fill in 30 seconds, stop
engine and determine the
cause.
6. After the system starts to
show signs of fill, slowly
move pump swashplate to a
slight cam angle. Continue to
operate system slowly with
no load on motors until sys-
tem responds fully.
7. Check fluid level in the reser-
voir and refill if necessary to
the proper level with an
approved filtered oil.
8. Check all line connections for
leaks and tighten if necessary.
9. The machine is now ready to
be put into operation.
10.Frequent filter changes are
recommended for the first
two changes after placing
the machine back into opera-
tion. Change the first filter in
3-5 hours and the second at
approximately 50 hours.
Routinely scheduled filter
changes are recommended
for maximum life of the
hydraulic system.
