7.6Change of grease in mower
elements
Replace the grease in the mower elements every 500 working
hours or every 1,000 hectares.
Follow the directions listed hereafter.
- Remove the mower disc.
If several bearing housings need to be dismounted, care
should be taken that they are fitted back on the original
mower elements.
- Dismount the bearing housing A (fig. 28) from the element.
Make sure 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 fill out of the bearings.
Measure the grease quantity carefully. An incorrect
quantity may cause overheating and damage of the
element.
- Fill the elements with 95 grams of grease (Shell Alvania
WR 0).
- Place the bearing housing on the element. Turn the hub (C,
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 at the catellated nut the presence of the O-ring D
(fig. 29) in the pressure piece.
- Fit the mower disc. Tighten the castellated nut with a
torque of 150-250 Nm (15-25 kgm) and secure it with a
split pin. Make sure that the split pin does not protrude
above the pressure piece.
