Safety precautions Safety precautions Always consider safety precautions before beginning a service procedure. Protect yourself and others from injury. Take the following general precautions whenever servicing a hydraulic system. Unintended machine movement W Warning Unintended movement of the machine or mechanism may cause injury to the technican or bystanders. To prevent uintended movement, secure the machine or disable / dis-connect the mechanism while servicing. Flammable cleaning solvents W Warning Some cleaning solvents are flammable. To eliminate the risk of fire, do not use cleaning solvents in an area where a source of ignition may be present. Fluid under pressure W Warning Escaping hydraulic fluid under pressure can have sufficient force to penetrate your skin causing serious injury and/or infection. This fluid may also be hot enough to cause burns. Use caution when dealing with hydraulic fluid under pressure. Relieve pressure in the system before removing hoses, fittings, gauges, or components. Never use your hand or any other body part to check for leaks in a pressurized line. Seek medical attention immediately if you are cut by hydraulic fluid. Personal safety W Warning Protect yourself from injury. Use proper safety equipment, including safety glasses, at all times. 4 Danfoss May 2018 AX00000353en-000201
Assembly instructions Overview This manual includes information on assembly and testing of Orbital X motors, OMP X and OMR X. To provide timely motor delivery when a customer places an order, you need to have all the necessary modules and equipment on hand. Orbital X is based on a modular building concept. Each motor consists of four modules; housing module, spool shaft module, gear set module and a screw module. When assembled, these four modules constitute a complete motor. Additional feature includes seal guard module and EMD module. Danfoss May 2018 AX00000353en-000201 5

Assembly instructions Keep it clean Follow these general procedures when assembling Orbital X Motors. Keep it clean. As with any precision equipment, keep all parts free of foreign material and chemicals. Protect all exposed sealing surfaces and open cavities from damage and foreign material. If left unattended, cover the motor with a protective layer of plastic. Lubricate O-rings Lubricate O-rings Additionally, lubricate all moving parts with oil, such as spool shaft, cardan shaft and gear set. Tools Proper assembly of Orbital X motors require following tools. You may use the dimensions and information in the drawings to fabricate them.
