Regreasing
Some gear unit designs (free drive shaft, Option W, agitator designs VLII and VLIII) are
equipped with a regreasing device.
For agitator versions VLII and VLIII, the vent screw located opposite to the grease nipple must
be unscrewed before regreasing. Grease should be injected until a quantity of 20-25g 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 regreased with approx.
20-25g of grease via the grease nipple provided
Recommended grease: Petamo GHY 133N (see Section 6.4: Klüber Lubrication).
Cleaning or replacing the vent screw
Unscrew the pressure vent, thoroughly clean the vent screw (e.g. with compressed air) carry out
a function test and fit the vent screw in the same place. If necessary, use a new vent screw.
Replacing the automatic lubricant dispenser
Screw-off the cartridge case cover (2), (see Figure 4-2). The lubrication dispenser (5) is screwed
out and replaced with a new component (Part No. 283 0100). Then activate (see Chapter 4.2)!
Changing the oil
The figures in Section 6.1 show the oil drain screw, the oil level screw and the pressure vent
screw for various designs. Sequence:
1. Place the drip tray below the oil drain screw
2. Completely remove oil level screw, screwed sealing plug with dipstick if an oil level tank is
being used and oil drain screw.
Note!
If the examination only shows slight wear (25% of the limiting value), it is permissible to
extend the interval for examination of the coupling to twice the normal period, i.e. 5000
operating hours and at least every year.
