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: A10VO (45 or 60) DFR-1/52
R
PUC.
A left hand rotating pump will have the letter “
L
” in its part number.
Example: A10VO (45 or 60) DRF-1/52
L
PUC.
Depending on genset model, a 45cc or 60cc pump is supplied. 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
between in the range specified in Table 1 for your model generator.
Example: For an HR-8 System that is to operate at 650 RPM engine speed:
PTO Ratio = 880 RPM ÷ 650 RPM = 1.35 or 135% (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.
