Change of grease in mower elements

7.6
Replace the grease in the mower elements every 500 working
hours or every 1000 hectares.
Follow the directions listed hereafter.
• Remove the mower disc.
• Dismount the bearing housing A (fig. 33) from the element.
Make sure that the shims B remain in place.
If several bearing housings need to be dis- mounted, 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 0,095 kgs 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.
33) so that it is aligned with the hub of the adjacent mower
element (fig. 34).
• Apply Loctite 243 to the thread of the fillister head screws and
tighten them with a torque of 20 Nm (2 kgm).
• Check the presence of the O-ring in the pressure piece D (fig.
34).
• 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.
