7.3.3 Replacing pressure filter element
(1) Pressure filter operating hydraulics
ADVICE
The filter element is a disposable product. It may not be cleaned. The filter element
can be destroyed by cleaning. The hydraulic system might sustain heavy damage.
Pressure filter operating hydraulics
The pressure filter for the operating hydraulics is located on the gearbox on the
right next to the drive of the front cardan shaft. First exchange of the filter element is
required after the first 50 operating hours, thereafter, annually. Besides a fluid-resis-
tant and sufficiently large catchment barrel, you will need a ring wrench or fork wrench
SW 32.
Filter exchange
– Shut down diesel engine.
– Unscrew the filter bowl. Catch the liquid in a suitable container and clean it respec-
tively dispose of it in an environmentally compatible manner.
– Pull the filter element from the element holding pin. Once the filter element is
removed, check if there is a metal end cap at the top. If this is not the case, pull off
the end cap separately from the element holding pin. Inspect the element surface
for dirt residue and larger particles. These might indicate damages of the compo-
nents.
– Clean the bowl.
– Inspect the filter for mechanical damage; check sealing surfaces and threads in
particular.
– Replace O-ring on the filter bowl. Dirt or incomplete pressure relief during disas-
sembly may lead to seizing of the bowl screw thread.
