7.6 Change 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.
- Dismount the bearing housing A (fig. 22) from the element.
Make sure that the shims B remain in place.
If several bearing housings need to be dismounted, care
should be taken that they are fitted back on the original
mower elements.
- 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.
- Fill the elements with 95 grams of grease (grease classi-
fication NLGI 0, type calcium-lithium soap or lithium
soap/Shell Alvania WR 0).
Measure the grease quantity carefully. An incorrect
quantity may cause overheating and damage of the
element.
- Place the bearing housing on the element. Turn the hub C
(fig. 22) so that it is aligned with the hub of the adjacent
mower element (fig. 23).
- Apply Loctite 243 to the thread of the M8 fillister head
screw and tighten them with the following torques:
36 Nm (3,6 kgm) for mower unit with castellated nut M22.
- Check the presence of the O-ring in the pressure piece.
- Fit the mower disc. Tighten the castellated nut with a
torque 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.
