AH24
IMPORTANT: In work where the hydraulic system is
subjected to abnormally heavy pollution (e.g. when
running with tipping trailers) the suction strainer must be
cleaned at shorter intervals. If the pump begins to
”shriek”, the engine should be stopped, the suction
strainer cleaned and the viscosity of the oil checked
against the manufacturer’s recommendations.
H 5.5.1. Removing and c leaning
--- Place the tractor with the front end higher so that less oil
runs out.
--- Loosen the wing nut on the end of the housing and pla-
ce a funnel or similar under the housing to collect up the
oil.
--- Remove the cover and drain off the oil into a suitable
container.
--- Carefully pull out the element.
--- Clean the element with diesel fuel and dry with com-
pressed air.
--- Also clean the magnetic plugs.
H 5.5.2. Fitting
--- Place the cleaned element in the housing
--- Replace the cover together with the seal and tighten the
wing nut by hand
--- Check the oil level in the hydraulic system.
IMPORTANT: Look for any foaming of the oil when
starting up again (check through the filling opening).
Foaming indicates that the cover seal is leaking and must
be changed or retightened.
