Tightening torques for friction factor
m
= 0.12; tolerance of the tightening torque ±10 %
Please note: increase the tightening torque by 10% for screwed connections with flat
gaskets.
Correcting the lubricant amount
If the oil quantity in the gearbox has been increased for long−term storage ( (
10) , the
oil must be drained completely and must then be refilled for the intended mounting
position. (
52). Carry out the following steps:
1. Place receptacle under oil drain plug.
2. Remove breathing / oil filler plug.
3. Completely drain lubricant.
4. Screw in oil drain plug.
5. Fill gearbox with correct oil quantity for intended mounting position (according to
nameplate).
6. Screw in ventilation / oil filler plug.
Condensation drain hole
Note!
Lenze delivers motors with condensation drain holes with sealed
condensation drain holes. The holes are sealed with a plastic plug or a
locking screw. This does not affect the type of protection and the motor is
protected against the ingress of foreign substances during transport and
operation. Further information, (
