Changing the Return Filter Element
1
Prepare the Machine
Position the machine on level ground. Stop the engine.
Remove the starter Key.
2
Locate the Return filter.
See
Components Location
Diagram
at the end of this section.
3
Release Tank Pressure.
See
Releasing Tank Pressure
.
4
Removing the Element
a
Remove the retaining bolts
A
and washers
B
and
take off the cover plate
C
complete with its 'O'-ring
seal.
b
Remove the spring
D
, bypass valve
E
and element
F.
5
Fit a New Element
Re-assemble in reverse order, using a new filter element
F
and replace the 'O'-ring with a new one if the one
removed is worn or damaged.
6
Seal the system
Refit the cover plate
C
and secure with bolts
A
and
washers
B.
Flushing Filters
A slave hydraulic flushing element can now be obtained for
the machine. It is a mandatory requirement that the hydraulic
system is flushed when:
1
The hydraulic system has become contaminated with
debris.
2
Major hydraulic components such as pumps, valve
blocks, ram, tanks, motors etc. are changed.
3
An oil sample report indicates that the system needs to
be cleaned.
The slave filter should be fitted in place of the main return
filter
during flushing only
.
1
Vent hydraulic tank pressure (see
Releasing Tank
Pressure
) and then remove tank cover
C
, main
hydraulic filter
F
, relief valve
E
and spring
D
.
2
Fit flushing filter element, relief valve
G
and spring
D
.
3
Refit tank cover
C
, ensuring that the ‘O’ ring is
positioned correctly.
4
Start up machine and test for leaks.
5
Run the machine as described below:
The filter should be left in the machine for a minimum of
4 hours, during which time all hydraulic services must
be operated a minimum of 20 times to ensure complete
system cleanliness.
6
After the required flushing time has elapsed, stop the
engine and vent hydraulic pressure (see
Releasing
Tank Pressure
).
7
Remove flushing filter element and save in a clean
condition until step 10 is completed.
8
Fit new main hydraulic filter and refit tank cover.
9
Take oil sample and send for analysis.
10
If analysis shows that the oil is out of specification the
flushing procedure should be repeated until analysis
confirms that the oil is satisfactory.
