START UP MAINTENACE - BDP-10L VARIABLE PUMP
Fluids
Fluids used with Hydro-Gear product should
be carefully selected with assistance from a
reputable supplier.
Typically, an API classification SG/CD engine
oil is used with a viscosity range equivalent to
20W50.
Start-up Procedure
The following start-up procedure should
always be followed when starting a new
installation or when restarting an installation
in which the BDP has been removed from the
system.
WARNING:
THE FOLLOWING PROCEDURE MAY
REQUIRE THE VEHICLE/MACHINE TO BE
DISABLED (WHEELS RAISED OFF THE
GROUND, WORK FUNCTION
DISCONNECTED, ETC.) WHILE
PERFORMING THE PROCEDURE IN
ORDER TO PREVENT INJURY TO THE
TECHNICIAN AND BYSTANDERS.
Prior to staring the BDP, make certain all
system components (reservoir, fittings, etc.)
are clean prior to filling with fluid.
Be certain to fill the BDP housing with
clean fluid prior to start-up.
Fill the housing
by pouring filtered oil into the upper case
drain port, if possible.
Fill the reservoir with recommended fluid
which should be filtered prior to entering the
reservoir.
The inlet line and filter leading from the
reservoir to the charge pump must be filled
prior to start-up. Check inlet line for properly
tightened fittings and make sure it is free of
restrictions and air leaks.
Pressurizing the inlet 2-4 PSI will aid in start-
up. “Jog” or slowly rotate the engine with the
swashplate in its neutral (0 angle) position
until charge pressure starts to rise (charge
pressure is defined as low side loop
pressure).
WARNING:
DO NOT START ENGINE UNLESS THE
PUMP IS IN THE NEUTRAL POSITION
(0 SWASHPLATE ANGLE) OR THE DRIVE
WHEELS ARE OFF THE GROUND.
Start the engine and run at the lowest
possible RPM.
With the bypass valve closed, slowly move
the displacement control in both the forward
and reverse directions. As air is purged from
the unit, the oil level in the reservoir will drop
and bubbles may appear in the fluid. Refill
the reservoir as necessary.
Place the displacement control in the neutral
position and open the bypass valve. Slowly
move the displacement control in both the
forward and reverse directions to purge the
air from the closed circuit.
Close the bypass valve and run the unit in
both directions for several minutes until any
remaining air is purged from the unit. Refill
the reservoir as necessary.
Shut down the engine, check for and correct
any fluid leaks, and check the reservoir level.
Add fluid if necessary. The transmission is
now ready for operation.
