Start-up Procedure

When starting a new or rebuilt transmission system, it is
extremely important to follow the start-up procedure. 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 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 filtered
through a 10 micron filter. Refer to Eaton Hydraulics
Technical Data Sheet number 3-401 titled Hydraulic Fluid
Recommendations.
4 For Gasoline engines or L.P. engines remove the coil wire
and turn the engine over for 15 seconds. For 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 injectors.
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 the engine and
determine the cause.
6 After the system starts to show signs of fill, slowly move
pump camplate to a slight cam angle. Continue to operate
system slowly with no load on motors until system
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
necessary.
The machine is now ready to be put into operation.
Frequent filter changes are recommended for the first two
changes after placing the machine back into operation. Change
the first filter in 3-5 hours and the second in approximately 50
hours. Routinely scheduled filter changes are recommended
for maximum life of the hydraulic system.
