Safety precautions
Always consider safety precautions before beginning a service procedure. Protect yourself and othersfrom 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 whileservicing.
Flammable cleaning solvents
W Warning
Some cleaning solvents are flammable. To eliminate the risk of fire, do not use cleaning solvents in anarea 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 seriousinjury and/or infection. This fluid may also be hot enough to cause burns. Use caution when dealing withhydraulic fluid under pressure. Relieve pressure in the system before removing hoses, fittings, gauges, orcomponents. Never use your hand or any other body part to check for leaks in a pressurized line. Seekmedical 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.

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 necessarymodules 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 modulesconstitute a complete motor. Additional feature includes seal guard module and EMD module.

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 andinformation in the drawings to fabricate them.

Starting pressure
1. Disengage the motor and ensure there is no outside load on the output shaft.
2. Slowly raise the oil supply pressure until the motor starts to the appropriate limit (7 or 10 bar [102 or145 psi]).
3. Check that the motor is still turning at this limit.
If the motor turns at this limit, it is good.
