Start-up Procedure
When initially starting a new or a rebuilt transmission system.
it is extremely important that the start-up procedure be fol-
lowed. It prevents the chance of damaging the unit which
might occur if the system was not properly purged of air
before start-up.
1.
After the transmission components 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 filter. Refer to Eaton Hydrau-
lics 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 seconds. Diesel engines: shut off
the fuel flow to the injectors and turn the engine over
for 15 seconds.
5.
Replace the coil wire or return the fuel flow to the injec-
tors. Place the transmission unit in the neutral position,
start the engine and run it at a low idle. The charge
pump should immediately pick up oil and fill the system.
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 reservoir and refill if necessary to
the proper level with an approved filtered oil.
8.
Check all line connections for leaks and tighten if neces-
sary.
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.
