Protect yourself and others from injury. Take the following general precautions whenever servicing a hydraulic system. Unintended machine movement WWarning Unintended movement of the machine or mechanism may cause injury to the technican or bystanders. To protect against uintended movement, secure the machine or disable / disconnect the mechanism while servicing. Flammable cleaning solvents WWarning Some cleaning solvents are flammable. To avoid possible fire, do not use cleaning solvents in an area where a source of ignition may be present. Fluid under pressure WWarning 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 WWarning Protect yourself from injury. Use proper safety equipment, including safety glasses, at all times.

Orbital Motors, C, and W/N Series and 8 Dismantling / Cleaning Dismantling (continued) Item Part to remove Comments 3 Output shaft Motors with integrated spigot flange: Place the motor housing on the work bench and press the shaft out of the motor housing. Shaft and bearings should normally not be removed from W N. However, if necessary for inspection and cleaning, remove the shaft from the housing by gently tapping the axle journal with a plastic hammer. The front bearing can thus remain in the housing. After this, turn the motor. Screws ( off) Use Torx-spanner type T30, 9 mm screwdriver or 4 mm hexagon socket spanner. 2 Washer Only W N 4 Spigot flange, O-ring, bearing race Motors with integrated spigot flange: Remove bearing and bearing race from the motor housing. 8 Needle bearing 3 Shaft seal Dust seal Motors with separate spigot flange: Use a 2 mm screwdriver Motors with integrated spigot flange: With mandrel and plastic hammer, carefully knock out the shaft seal. Motors with separate spigot flange: Knock out the shaft seal / dust seal with a plastic hammer. Use mandrel SJ -9000- or SJ F9000-9 Bearing race Only /W N with ø32 mm/28. mm tapered shaft. Use a 2 mm screwdriver. 2 Check valves (2 off) Only with check valves. Pull the check valve out with, for example, a ground (shortened) 3. mm screw tap. Cleaning Cleaning Clean all parts carefully with low aromatic kerosine. Inspection and replacement Check all parts carefully and replace if necessary. Lubrication Before assembly, lubricate all parts with hydraulic oil and grease rubber parts with vaseline. 028 Rev AC Sep 200 3
Orbital Motors, C, and W/N Series and 8 Assembly Assembly Item Part to install Comments Place the motor housing in the holding tool with the flange upwards. 2 Check valves (2 off) Only with check valves Grease the check valves (fitted with new O-rings) and fit them in their bores with light blows using plastic hammer. 9 Bearing race Only /W N with ø32 mm / 28. mm tapered shaft. Shaft seal Motors with integrated spigot flange: Lubricate the shaft seal on the outside with hydraulic oil. Fit the shaft seal correctly onto mandrel SJ -044 and carefully press the shaft seal into position in the motor housing. Motors with separate spigot flange: Knock the seal into position in the spigot flange. Check that the seal lies against the cover recess. Use mandrel SJ -9000- or SJ F9000-3 Dust seal ring Place the dust seal ring in the spigot flange and knock it into position with a plastic hammer and appropriate mandrel. SJ -9000- or SJ F9000-, Bearing race O-ring Motors with integrated spigot flange: Fit bearing and bearing race onto the shaft and mount together with the shaft. Motors with separate spigot flange: Grease the O-ring with vaseline and fit the bearing race and O-ring into the spigot flange. 8 Needle bearing 4 Spigot flange Turn so that the holes line up. 2 Washer Only W N Screws ( off) Tightening torque Torx screws M: -8 Nm [4-0 lbf in] Slotted screws M: -8 N m [4-0 lbf in] Hexagon socket screws M: -0 N m [4-0 lbf in] Hexagon socket screws M: 2- N m [4-0 lbf in] After this, turn the motor. 3 Output shaft Grease the journals with hydraulic oil. The rear shaft end must be marked before fitted. The mark must be positioned vertically above a commutation slot leading up to the front annular channel. For W N, guide the shaft into the motor housing back with the rear needle bearing fitted on the shaft. Bring the shaft in line with the back of the motor by gently tapping the shaft with a plastic hammer. Check that the shaft rotates easily O-ring Grease the O-ring and put it in the O-ring groove of the housing. Distributor plate Turn the distributor plate so that the holes line up. 4 028 Rev AC Sep 200
Orbital Motors, C, and W/N Series and 8 Assembly Assembly Item Part to install Comments 4 Cardan shaft Guide the cardan shaft down into the motor housing. Only 2, 32 and 40 Place the assembly tool under the upper splines of the cardan shaft. In case of different splines lengths turn the cardan shaft to ensure the long splines end is fitted in the output shaft. Transfer marking from output shaft to cardan shaft. 8, Gearwheel set Place the O-rings (greased) in the O-ring grooves of the gearwheel. In gearwheels with non through splines place the gearwheel with the recess in the spline hole facing down towards the housing. Place the gearwheel set on the cardan shaft so that the top of a tooth in the external teeth of the gearwheel is vertically above the mark on the cardan shaft. Turn the gearwheel set counter clockwise until the cardan shaft and the gearwheel start to mesh ( ). Turn the gearwheel rim so that the holes made for the screws line up. 9 End cover Turn the end cover so that the holes line up. 20, 2 Washer, screws Use a 3 mm spanner socket Tightening torque: 30-3 N m [2-30 lbf in]. 24, 2 Washer, drain plug Use a mm spanner socket. Tightening torque: 30-0 N m [20-3 lbf in]. 28 Seal plugs Threaded plug (if present) End port version: Screw plastic plugs into end ports. Screw in the side port plugs using 0 mm hexagon socket spanner. Tightening torque: 0-0 N m [44-20 lbf in].
