HYDRAULIC SYSTEM REQUIREMENTS
Refer to the performance charts, below, to properly match your hydraulic system to winch performance.
The charts consist of:
(1) Line pull (lb.) first layer vs. working pressure (PSI) and (2) line speed, first layer (FPM) vs. gallons per
minute (GPM). Performance based on a motor displacement of 10.3 cubic inches/rev with 60 GPM
maximum flow rate. Motor has (2) 1”-12 SAE straight thread o-ring ports.
Note:
A motor spool (open center) directional control valve is required for brake operation.
