Pump Installation - Efco SWAPLOADER SL-412 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 (1-1/2"
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. The pressure hose from the hydraulic pump to the control valve
assembly is not supplied with the hoist as it must be made to the
proper length. This hose must be purchased from a local hydraulic
hose assembly supplier per the following specification:
a. Hose ID: 3/4 inch
b. Working Pressure: 3500 PSI
c. Hose Fitting Threads: SAE 37° (JIC) 1 1/16-12
