5.2.7.3 Drying agent filter (Option: DB)
NOTICE!
Gear unit damage
The separate filter manufacturer’s documentation must be observed.
The drying agent filter uses silica gel as the filter material. The condition of the filter is visible from the
outside. With increasing contamination the colour of the filter material changes from blue to pink. The
colour change starts in the lower area and spreads to the upper area The filter should be replaced
when three quarters of the filter have changed colour.
1. Check the degree of contamination.
2. Optional: Unscrew the old ventilation filter.
3. Optional: Screw in the new ventilation filter with a new sealing ring (7.4 "Torque values").

Hose lines are used as intake and pressure lines for lubricant circulation and for cooling units. In
addition, if an oil tank is present, this is connected to the gear unit with hose lines.
Hose lines are subjected to a natural ageing process due to external influences (e.g. UV radiation) to a
greater extent than pipes.
When checking hose lines, look out for leaks, cuts, cracks, porous areas and chafing. In such cases,
the affected hose lines must be replaced. Please contact the NORD Service department.
