The L and K Frame variable motors are light to medium power two-position axial piston motors incorporating an integral servo piston.  They are designed for operation in closed and open circuit applications.  The L and K Frame motors consist of five unique rotating groups (displacements) and two housing (mounting) configurations. An SAE-B, two-bolt, and a cartridge style (for space-optimized gearbox mounting) configurations are available for each frame.  Maximum speeds and maximum applied pressures for each displacement vary.   The standard control is a direct acting single line hydraulic control.  For SAE-B mount motors a two line control is also available.  The integral servo piston controls motor displacement.
The motor is spring biased to maximum displacement and hydraulically shifted to minimum displacement.  Minimum and maximum displacement can be set with fixed internal stops.  The large diameter servo piston allows smooth acceleration and deceleration with relatively large circuit orificing.
The motor is ideally configured for installations requiring compact packaging and optimized plumbing, such as wheel ends.  One face of the motor contains all hydraulic porting. Two standard porting configurations are available: twin radial (side) or axial (end) O-ring boss main ports.
