Pump Installation - Efco swaploader SL-105 Parts And Operation Manual

To better understand the effects of pump rotation we must consider the path that oil takes
through the pump. Oil enters the pump through the inlet (suction) port, travels around the
outside of the gears, and is forced out through the outlet (exhaust) port. Oil enters and exits the
pump in the direction of its rotation.
Determine pump rotation by positioning the pump belly side down (see illustration above).
Looking at the rear of the pump if the suction (largest) port is to the left side, then the pump is a
CCW or left-hand rotation. If the suction (largest) port is on the right side, then the pump is CW
or right-hand rotation.
1. Install the hydraulic pump to the P.T.O. (Bolts are not
provided).
2. Install the hydraulic fittings into ports on the hydraulic pump as
shown on Pg. 5-10.
3. Connect the suction hose assembly to the hydraulic tank (1"
I.D. hose) and route to the hydraulic pump in as short and
straight line as possible. Be sure to route the hose clear of
exhaust components and of the drive shaft. Extra hose is
provided so the hose can be shortened to an appropriate
length. Install the hose on the hose barb fittings at the tank and
at the pump and secure with the hose clamps provided.
NOTE: Prior to startup, this hose must be filled with oil.
4. Connect pressure hose assembly (1/2" I.D. hose) to control
valve inlet and route to the pump the same as the suction line.
This hose is provided with only one fitting, so the hose can be
shortened to appropriate length. Remove the hose and shorten
as required. After the hose has been shortened, lubricate the
insert threads of the fitting and the I.D. of the hose.
