1 Flange Couplings with Cylindrical Interference Fit /FC Mounting the coupling onto the machine shaft 1.3 Mounting the coupling onto the machine shaft 1. Clean the shaft and bore of the flange coupling thoroughly and remove any grease. The disassembly bores of the coupling must also be free from dirt. 2. NOTICE! Improper mounting may result in damage to the coupling. Possible damage to property. Make sure that the shaft and bore are completely free from grease to ensure proper functioning of the interference fit. Do not use assembly paste during assembly. 3. Heat the flange coupling to a joining temperature of 230 C as long as no special joining temperature is specified for the order. 4. CAUTION! The required assembly clearance is achieved only by heating the coupling. Important: Risk of burns during the assembly process. Make sure that hot parts cannot be touched unintentionally. 5. NOTICE! Radiant heat from the flange coupling can damage adjacent elements. Possible damage to property. Protect adjacent elements (e.g. oil seals) with suitable heat shields. 1153862283 6. Mount the flange coupling quickly onto the shaft up against the shaft shoulder. Prepare mounting tools and plan the process carefully so that the coupling can be fitted to the shaft quickly. During the cooling process, the coupling must be secured on the shaft. Once the coupling has cooled down, spray the disassembly bores with clean mineral oil and close them using the supplied screw plugs. 1153865867 4 Addendum to the Assembly and Operating Instructions X..

Flange Couplings with Cylindrical Interference Fit /FC Mounting the flange connection 1 1.4 Mounting the flange connection NOTICE Improper mounting may result in damage to the coupling. Possible damage to property. Note that the flange coupling cannot compensate shaft misalignments. 1. Clean the flange surfaces [1] of the coupling halves [2]. [2] [1] 992697355 2. Align the bore patterns of the two coupling halves [2] and join the flange coupling. [2] 9007200247441547 Addendum to the Assembly and Operating Instructions X..

When you use other screws than the screws included in the delivery, the tightening torques must be adjusted to the new friction conditions. Only use the following tools for the installation: Signal-generating torque wrench Motorized torque wrench with dynamic torque measuring Torque-controlled, gradual hydraulic tools Size Thread Tightening torque Strength class Nm X100-110 M20 555 X120-130 M24 960 X140-150 M30 1910 X160-190 M36 3320 X200-230 M42 5310 X240-280 M48 7990 X290-320 M56 12690 10.9 6 Addendum to the Assembly and Operating Instructions X..

Flange Couplings with Cylindrical Interference Fit /FC Removing the coupling from the shaft 1 1.5 Removing the coupling from the shaft 1.5.1 Notes CAUTION Risk of jamming and crushing due to improper removal of heavy components. Risk of injury. Disassemble the flange coupling properly. Observe the following instructions for disassembly: NOTICE Improper disassembly may damage the output shaft bearing. Possible damage to property Do not apply any tools between the coupling and the gear unit housing. To remove the coupling [1], the interference fit must first be expanded hydraulically. The remaining holding force must then be overcome with an extractor [2]. The following figure shows an exemplary design of a hydraulic extractor. [1] [2] For disassembling the coupling, one oil pump is required per disassembly bore. 1071755147 Addendum to the Assembly and Operating Instructions X.. Series Helical and Bevel-Helical Gear Units 7

Loosen the bolts [1] and separate the flange coupling. Remove the screw plugs [2] of the disassembly bores. Prepare disassembly tools and the process carefully, so that the flange coupling can be removed from the shaft quickly. [2] [1] 9007200360563851 2. Connect the first oil pump [3] to the disassembly bore closest to the flange [4] and apply pressure until oil comes out of the second disassembly bore [5]. Depending on the size, this bore can also be located on the flange surface of the coupling. It is essential that you observe the manufacturers' safety notes of the hydraulic devices during the disassembly process. 8 Addendum to the Assembly and Operating Instructions X..

Flange Couplings with Cylindrical Interference Fit /FC Removing the coupling from the shaft 1 [3] [4] [4] [5] 9007200255373323 3. Connect the next oil pump [6] to this bore [5] and press in oil until it comes out at the next disassembly bore [7]. [7] [6] [5] 1002542475 4. Repeat this process until all disassembly bores are connected to an oil pump and pressure is applied. At the last disassembly bore [7], the pressure must be increased until at both front faces of the coupling [8] oil comes out in the shape of a ring. The coupling can also be disassembled with only one oil pump. In this case, the individual disassembly bores must be blocked after pressure has been applied. Provide for a consistent pressure throughout the disassembly procedure. Addendum to the Assembly and Operating Instructions X.. Series Helical and Bevel-Helical Gear Units 9
1 Flange Couplings with Cylindrical Interference Fit /FC Removing the coupling from the shaft Before removing the coupling, keep the oil pressure constant for approximately 30 minutes to create an evenly distributed oil film inside the interference fit. The pressure must be kept constant during this time and the remaining disassembly process at all bores. [7] [8] 9007200257290379 5. Install the extractor [3]. Remove the coupling from the shaft. Since the oil pressure breaks down after the last disassembly bore has been reached, the required force for removing the coupling is significantly higher at the end. [3] [4] 1000624651 6. Check the condition of the shaft and the coupling bore after the disassembly process. Damaged parts must be replaced. 10 Addendum to the Assembly and Operating Instructions X..
