Mechanical Installation
Required tools / material
Set of spanners
• Torque wrench (for shrink discs, AQ motor adapter, input shaft assembly with centering shoulder)
• Mounting device
• Shims and distance rings, if necessary
• Fastening devices for input and output elements
• Lubricant (e.g. NOCO® fluid)
• Agent for securing screws, e.g. Loctite 243 (for input shaft assembly with centering shoulder)

Preliminary work
The output shafts and flange surfaces must be thoroughly cleaned of anti-corrosion agents, contamination or such like (use a commercially available solvent). Do not let the solvent come into contact with the sealing lips of the oil seals – material damage! Long-term storage of gear units.
Gear units of the “extended storage” type have
• a mineral oil fill (CLP) or synthetic oil fill (CLPHC) suitable for the mounting position so the unit is ready to run. However, you should still check the oil level prior to startup (see section "Inspection/Maintenance" / "Inspection/Maintenance work").
• a higher oil level with synthetic oil CLP PG). Correct the oil level prior to startup (see section "Inspection/Maintenance" / "Inspection/Maintenance work").

Installing the gear unit
The gear unit or geared motor must be mounted/installed in the specified mounting position on a level1, vibration-absorbing and torsionally rigid support structure (Spiroplan® gear units are not dependent on mounting position). Do not tighten housing legs and mounting flanges against each other and pay attention to the approved overhung and axial loads
Use only bolts of 8.8 quality for installation of the geared motors, Use bolts of 10.9 quality for fastening of flanges to transmit the rated torques listed in the catalog for the following helical geared motors in flange design (RF..) and in foot/ flange version (R..F):
• RF37, R37F with flange-Æ 120 mm
• RF47, R47F with flange-Æ 140 mm
• RF57, R57F with flange-Æ 160 mm
At this point of assembly, please check that the oil filling is as prescribed for the mounting position (see "Lubricants" / "Lubricant fill levels" or data on nameplate). In case of mounting position change, adjust lubricant filling quantities accordingly. Please consult our service department, if the mounting position for K gear units is changed to M5 or M6 or within these mounting positions. Please consult our service department, if the mounting position of S units in sizes S47 ... S97 is to be changed to mounting position M2. Use plastic inserts (2 – 3 mm thick) if there is a risk of electrochemical corrosion between the gear unit and the driven machine (connection between different metals such as cast iron and high-grade steel)! Also fit the bolts with plastic washers! Ground the housing additionally – use the grounding bolts on the motor. Installation in damp areas or in the open Gear units are supplied in corrosion-resistant versions for use in damp areas or in the open air. Any damage to the paintwork (e.g. on the breather valve) must be repaired.

No ventilation is required for R17, R27 and F27 gear units in mounting positions M1, M3, M5 and M6 as well as Spiroplan® W gear units. All other gear units are delivered by SEW ready for the mounting position with the breather valve and transport fixture fitted.
Exceptions:
Gear units for long-term storage, in pivoting or inclined mounting positions are supplied with a screw plug installed in the provided vent hole. Prior to startup, the customer must replace screw plug at the highest location by the supplied breather valve.
• With geared motors for long-term storage, pivoting or inclined mounting positions, the supplied breather valve is located in the motor terminal box.
• With gear head units that have to be vented on the input side, the breather valve is supplied in a plastic bag.
• No breather valve will be supplied for gear units in enclosed design. Activating the breather valve
Usually the breather valve is activated in the plant. Should this not be the case, the transport fixture must be removed from the breather valve prior to the startup of the gear unit!
