Pre-Installation Guide
1.
Verify that the Power Take Off (PTO) and the pump rotations match.
To identify the pump rotation, check the pump part number found on the metal tag
attached to side of the pump. A right hand rotating pump (the standard pump
offered by Smart Power Systems), will have the letter “R” in its part number.
Example: K3VL80/B-10R
A left hand rotating pump will have the letter “L” in its part number.
Example: K3VL80/B-10L
To determine the PTO rotation, check the PTO manufacturer’s specification or
observe the PTO when it is engaged with the vehicle’s engine running.
A right hand rotating pump requires a PTO that turns counter-clockwise when
looking at the free end of the PTO shaft. A left hand rotating pump requires a PTO
that turns clockwise when looking at the free end of the PTO shaft.
WARNING:
Operating the pump with reverse rotation will damage the pump and void the
system’s warranty.
2.
Verify that the PTO ratio is properly sized to provide adequate speed to the
hydraulic pump during normal operation of the generator system. The PTO output
speed must be between 800 to 3,000 RPM for normal operation.
Example: For a HR-15 system, that is to operate at 650 RPM engine
speed: PTO Ratio = 800 RPM ÷ 650 RPM = 1.23 or 123%
WARNING:
Never exceed the maximum pump shaft speed. Pump failure or premature pump
wear will result. Doing so will void the system’s warranty.
3.
The hydraulic pump used for the SPS 12 kW and 15kW systems is too heavy to
mount directly onto a PTO. The pump must be mounted remotely with a bracket to
either the vehicle’s transmission or the vehicle’s chassis, and driven by a drive
shaft. Contact the PTO manufacturer and/or the drive shaft manufacture for
installation instructions for remote mounting a hydraulic pump.
