Pre-Installation Check List
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 speed
must be in the range specified in Table 1 for your model generator.
Example: For an HR-25/30 System that is to operate at 650 RPM engine speed:
PTO Ratio = 1200 RPM ÷ 650 RPM = 1.85 or 185% (or higher)
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.
Verify the combined weight of the pump and hoses filled with hydraulic fluid do not
exceed the PTO manufacturer’s weight restriction. If the pump weight does exceed
this restriction, the installer has two options: A) a bracket to support the pump can
be implemented, or B) the pump can be mounted to the vehicle chassis, connected
to the PTO with a drive shaft.
4.
Verify that the pump shaft will mount to the PTO. Pumps supplied by Smart Power
®
Systems have a SAE ‘C’ 2 bolt flange.
