3. Drain all the oil from the gear unit.
4. If the screw lock coating of the oil drain screw or oil level screw is damaged in the thread, a
new oil level screw must be used or the thread cleaned and coated with securing lubricant,
e.g. Loctite 242, Loxeal 54-03 prior to inserting. Check the sealing ring for damage. Replace
with a new sealing ring in case of damage.
5. Support the seal ring, insert the oil drain screw into the hole and tighten to the correct
torque! (See Chapter 6.3 for torque values)
6. Using a suitable filling device, refill with new oil of the same type (see rating plate,
Sections 3.4and 6.2) through the oil level hole until oil emerges from the oil level hole. (The
oil can also be filled through the pressure vent screw or a sealing plug located higher than
the oil level). If an oil level vessel is used, fill the oil through the upper inlet (thread G1¼)
until the oil level is set as described in Section 4.1.
7. Wait at least 15 minutes, or at least 30 minutes if an oil level tank is used, and then check
the oil level. Proceed as described in Section 4.1.
Danger!
Warning: Hot oil!
Note!
The oil does not need to be changed on gear units without oil level screw (see Section
6.1). These gear units are lubricated for life.
Note!
Standard ATEX category 3G and 3D helical gear units (See rating plate, Section 3.4) do
not have an oil level screw. Here, the oil is topped up through the threaded pressure
vent bolt using the quantities listed in the table in the following table.
