Electric, belt or crank driven hydraulic pumps can be used to power snow plows or hydraulic implement lifts.
HY-LO-JEEP – belt driven with attached reservoir, attaches to generator with strap.
HY-LO-JACK – belt driven without attached reservoir, attaches to generator with strap.
Monroe – crank driven
Newgren – crank driven
Stratton – crank driven
Love – belt driven, attaches to generator with strap.
The Monroe and probably the Stratton (the drawing in the Stratton brochure
looks like the Monroe pump ) use a three tabbed crank pulley (part # WO-646698) and a rubber coupler
to drive the pump as pictured in the diagram below.
The unedited diagram and all the Monroe part numbers are available in the Monroe Hydraulic Implement Lift Parts List
At least the early Newgren (and the pump we have) used the flat pulley as shown in the digram below from the Newgren Installation Instructions
