OPTIONS SPECIALS DESIGN Do not run in brake, wearing the plates will reduce the static capacity. Dynamic use of the brake is not recommended and should only be used in emergency situations. The disc pack should be replaced after ten dynamic uses. Times may vary depending on fluid viscosity and valves used. During low temperature applications, flushing the brake housing is recommended to maintain a constant oil viscosity. All data is based on ISO46 fluid at 40°C/[122°F]. If a different fluid will be used, please consult Rotary Power.

PRODUCT CAM FRONT MODULE PORT MODULE REAR BRAKE OPTIONS SPECIALS DESIGN The XJ motor code defines the starting direction of the motor. This is selected by the customer to best suit their application needs. The starting direction is based on flow being supplied to port A. A single speed motor can have its starting direction reversed by supplying flow to port B. In two speed motors, pressurising port A is preferred as this prevents the motor from recirculating high pressure oil when shifted into second displacement. It is important to select the correct starting direction of a two speed motor to...
