5.2.10 Oil change
WARNING
Risk of burns and injuries
• Allow the hot gear unit to cool down before touching it. However, the gear unit should still be warm
so that the oil can drain out faster.
• Wear protective gloves and goggles when changing the oil.
Information
Getriebebau NORD recommends regular analysis of the gear oil to optimise the oil change interval.
The position of the oil drain screw or the optional drain tap, the vents and devices for checking the oil
level should be obtained from the order-related dimension sheet.
For gear units with circulation lubrication and cooling system, replace the oil according to the
maintenance instruction for the circulation lubrication and the cooling system.
Procedure:
1. Choose a collection vessel according to the oil quantity stated on the name plate. Place the
collection vessel under the oil drain screw or the oil drain tap.
2. Unscrew the vents from the gear unit.
3. Unscrew the oil drain screw from the gear unit. With a drain tap, unscrew the closing cap from the
drain tap and open the drain tap.
4. Completely drain the oil from the gear unit. If present, also empty filters and piping.
5. In order to remove oil sludge particles, due to wear and old residues, flush the oil space. For this,
use the same type of oil which is used during operation.
6. Clean the thread of the oil drain screw or the screw plug of the oil drain tap. Coat the screw with
securing adhesive, e. g. Loctite 242 or Loxeal 54-03. Tighten the screws with the correct torque
((see chapter 7.4 "Screw tightening torques")).
7. Fill the gear unit with the specified quantity of fresh oil according to the name plate through the vent
hole. If the gear unit is equipped with a dipstick, the oil may be filled through this hole.
8. Check the oil level according to Section 5.2.5 "Oil level"after 15 minutes, for a gear unit with oil
reservoir tank, after 30 minutes. Correct the oil level as necessary.
