HOW TO IDENTIFY WHAT PUMP IS NEEDED
The SwapLoader factory supplied pump is a bushing style gear pump, because of the pressure
requirements of the SwapLoader hooklift hoist. By design the bushing style pumps are single
rotation (rotation specific).
All SwapLoader hooklift hoists come standard with a CCW (left hand rotation pump), which will
work for most manual transmission applications. For most automatic transmission applications a
CW (right hand rotation pump) is needed; call SwapLoader for price and availability.
NOTE:
Consult the PTO supplier whenever uncertain about the correct pump rotation for a
particular application.
The table below lists the SwapLoader part number for both left and right hand rotation pumps for
the SL-2418 hoist model:

HOW TO IDENTIFY PUMP ROTATION
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.
