7.6 Replacement of grease in mower
elements
Replace the grease in the mower elements every 500 working hours
or every 1,000 hectares.
Proceed as follows:
- Remove the mower disc.
If several bearing housings need to be dismounted, ensure
they are fitted back on the original mower elements.
- Dismount the bearing housing A (fig. 28) from the element.
Ensure that the shims B remain in place.
- Remove the grease from the element. Do not use a solvent since
it may affect the sealing of the bearings and/or rinse the grease
out of the bearings.
Measure the grease quantity carefully. An incorrect quantity
may cause overheating and damage to the element.
- Fill the elements with 100 g of grease (Shell Alvania WR 0).
- Place the bearing housing on the element. Turn the hub (fig. 28)
so that it is aligned with the hub of the adjacent mower element
(fig. 29).
- Apply Loctite 243 to the thread of the fillister head screws and
tighten them with a torque of 39 Nm (3.9 kgm).
- Check whether the O-ring D (fig. 29) is in the pressure piece.
- Fit the mower disc. Tighten the castellated nut with a torque of
150-250 Nm (15-25 kgm). Secure the castellated nut with a split
pin. Ensure that the split pin does not protrude above the pressure
piece.
N.B. the nut may not be turned back; keep turning it until the split
pin can be fitted.
