Page 3: Introduction
INTRODUCTION GENERAL The Denison Goldcup series 11 and 14 axial piston motors feature advanced design concepts which are time proven and aid in providing smooth controlled power in a compact package. The instructions contained in this manual cover installation, maintenance and repair of the Goldcup series motors. Before proceeding with the disassembly or reassembly of any unit, study this manual to become familiar with the basic fit and function of the internal parts. -
Page 4: Installation
INSTALLATION MOUNTING The mounting hub and four bolt mounting flange conform to SAE-E configuration. The motor must be mounted on a base or bracket of sufficient strength to support the unit without flexing or movement. It is recommended that a dial indicator be used when checking alignment. The concentricity of the pump shaft and driven load shaft must not exceed .010”... - Page 5 INSTALLATION (continued) Cycle unloaded equipment at low speed and pressure. Observe for proper function of all components. Bleed system of any trapped air. Re-check fluid level and fill as necessary. Gradually increase speed and pressure settings. Be alert for leaks, particularly in pump and motor inlet lines, as these may cause cavitation and eventual pump failure.
- Page 6 TABLE II TROUBLESHOOTING CHART TROUBLE SHOOTING Component problems and circuit problems are often inter-related. An improper circuit may operate with apparent success but will cause failure of a particular component within it. The component failure is the effect, not the cause of the problem. This general guide is offered to help in locating and eliminating the cause of problems by studying their effects.
