7.3
Intermittent maintenance
Intermittent maintenance has to be carried out:
• at the start of the season;
• before prolonged storage of the machine;
• when the machine is used extensively during the season.
- Grease all points of the machine listed in “7.2 Lubri-
cation”.
- Grease the spring-loaded locking pins of the yoke lock of
the PTO shaft.
- Check if the PTO shaft telescopes smoothly. A damaged
PTO shaft may cause excessive wear and tear to the
machine and tractor.
- Check all bolts and nuts for tightness.
Particular attention should be paid to the bolts of the trough
top lids, gearbox and bearing housings.
When tightening loose bolts/nuts the torques listed below
should be applied, with the exception of the bolts which
connect the support tubes to the headstock (fig. 16). For
these bolts the following torques are applicable:
M10-10.9: 55 Nm (5,5 kgm)
M12-10.9: 95 Nm (9,5 kgm)
- Check the tightness of the tines.
Correct torque: 600 Nm (60 kgm).
- Check the machine for damage and flaws.
- Check the correct grease level in the trough: 2-3 cm up
from the bottom of the gears.
There is no need to change the grease. In case of loss of
grease, add ESSO EHL 484 XC or some other type of
grease on a calcum-lithium or lithium basis which meets
the NLGI O classification. Proceed to a change of grease if
it was contaminated by soil or if its effectiveness was
affected by some other cause.
- Check if the breather (fig. 17) of the gearbox is sufficiently
clean. Due to the pressure increase in the gearbox, leakages
may occur.
