--- Clean surrounding parts
--- Loosen the filter and take out the element
--- Wash the filter housing with diesel fuel and fit the new

changed.
--- Tighten the filter with a suitable wrench to a torque of
200 Nm.
NOTE: Always change the filter when carrying out
repairs caused by impurities in the hydraulic system.
Clean suction strainer as described earlier (see service at
1000 hours intervals page 78).
CAUTION: If the external hydraulics are used
extensively and no return oil filter is used, the filter
must be changed ever 250 hours.
If the external hydraulics are used extensively it is
recommended that a return filter should be mounted in
the line (extra equipment).
On tractors with a return filter, all oil which is returning
from the outside machine, goes through the return filter.
Follow to changing intermediate on the return filter.

--- For refilling the oil, first open the breather filter (2)
together with the fastening tube (3) by opening the
locking nut (4) (hole inside the breathers fastening tube
is too small for refilling the oil).

on the dipstick (1) corresponds to 25 l, the upper mark
to 35 l. The system may be filled to any level between
these two points.
