Visual inspection of hose
Gear units with an oil tank (Option OT) and external cooling units have rubber hoses. After assembling
the oil lines, fill the gear unit housing with the gear oil type and quantity that is printed on the type
plate. Please contact the NORD service department.
Re-greasing
Some gear unit designs (free drive shaft, Option W, agitator designs VL2 and VL3) are equipped with
a re-greasing device.
For agitator versions VL2 and VL3, the vent screw located opposite to the grease nipple must be
unscrewed before re-greasing. Grease should be injected until a quantity of 20 - 25 g escapes from
the vent hole. After this, the vent plug must be reinserted and tightened.
For Option W and some IEC adapters, the outer roller bearing must be re-greased with approx. 20 -
25 g of grease via the grease nipple provided. Remove any excess grease from the adapter.
Recommended grease: Petamo GHY 133N(please see chapter 6.2 "Lubricants")(Klüber Lubrication),
a food compatible grease is possible as an option.
