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.


Safety precautions


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.

Install spool shaft

The rear shaft end must be marked before it is fitted. The mark must be positioned vertically above acommutation slot leading up to the front annular channel.

To prevent check valve from falling out and to protect shaft seal during assembly, please use specialtools: ED075904 (check valve), and ED074514 (torpedo).

1. Place check valve tool onto housing in one of the commutation holes and O-ring groove.

2. Place torpedo into housing, and press out when shaft is installed.

Shaft should be positioned in two different ways, depending on Motor type (OMP X or OMR X).

OMP X and OMR X with offset ports central commutation groove turned about 5 degrees fromthe center of the housing (counter-clockwise rotation). After inserting spool shaft into housing,turn the shaft so that it aligns with the center of the housing.




OMP X and OMR X with aligned ports central commutation groove in coincidence with thecenter of the housing.

3. Grease the O-ring and put it in the groove of the housing.

4. Ensure the spool shaft edge is slightly below motor housing.

OMP X and OMR X offset ports

The shaft must be positioned with the groove offset with regard to the inner circle of holes in thehousing.

Correct positioning of shaft (offset ports):




OMP X and OMR X aligned ports

Correct positioing of shaft (aligned ports)




Distributor plate

Mount the distribitor plate (pos. 13) on the housing.

Make sure that the distributor plate holes align with holes in the housing.

Distributor plate holes must align

Cardan shaft

1. Guide the cardan shaft down into the motor housing.

In case of different spline lengths, turn the cardan shaft to ensure the long spline end is fitted to inthe output shaft.

2. Transfer marking from output shaft to cardan shaft.

Marking transfer indicated

3. For smaller displacement, retain the cardan shaft using the fork tool (ED075353).

Viscosity range 35 ± 3 cSt

Oil cleanliness 22 18 13 - contamination degree, ISO 4406

Rotation

With the shaft pointing toward you and the system ports facing up, the motor must turn to the right(clockwise) when supplying pressure connection port A.

If the motor begins to turn below the specified pressure, the motor check is OK.

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.
