Denison Hydraulics Goldcup 6, Installation & Overhaul Instructions, Page: 4 / 24

SECTION 1 - INTRODUCTION
General The Denison Goldcup 6 and 7 axial piston motors feature advanced design concepts which
are time proven and provide for smooth controlled power. The instructions contained in this
manual cover complete disassembly and reassembly of the unit. Before proceeding with
the disassembly or reassembly of any unit, this manual should be studied in order to
become familiar with proper order and parts nomenclature.
Description The use of a rocker cam to control the motor displacement provides a small package size,
reduces wear, and speeds control response. The control vane actuator eliminates linkage
and backlash inherent in typical stroking cylinder designs.
Standard control for the units is cylinder control with adjustable maximum and minimum
displacement stops. Additional optional controls are also available. This unit is bi-
directional.
