3.6 Fitting push-on gear units with fastening element (option: B)
Risk of severe injuries
If the screw fastenings of the torque arm are removed during operation, the gear unit will rotate
around the output shaft.
• Secure the screw fastening against loosening, e.g. with Loctite 242 or a second nut.
The gear unit may be damaged by axial forces.
Bearings, gearwheels, shafts and housings may be damaged by incorrect fitting.
• Use a suitable pulling device.
• Do not strike the gear unit with a hammer.
Assembly and subsequent dismantling is facilitated by applying an anti-corrosive lubricant to the shaft
before fitting (e.g. NORD Anti-Corrosion Part No. 089 00099). Excess lubricant may escape after
fitting and may drip off. This escape of grease is not due to a leak in the gear unit. Thoroughly clean
these points on the output shaft after a running-in time of approx. 24 hours.

For push-on gear units with cover cap IP66 (Option H66) and fastening element (Option B) the
pressed-in closing cap must be pushed out before installing the gear unit. The pressed-in closing cap
may be destroyed during dismantling. A 2nd closing cap is supplied as a spare part. Fit the closing
cap after installation of the gear unit as described in Section 3.9 "Fitting the covers (option: H, H66)".
