Change of grease in mower elements

7.6
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. 29) 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
classification 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. 29) so that it is aligned with the hub of the adjacent
mower element (fig. 30).
- Apply Loctite 243 to the thread of the fillister head screws
and tighten them with a torque of 20 Nm (2 kgm).
- 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.
