HYDRAULIC PUMP LOAD SENSE FILTERS
The hydraulic pump load sense filters help keep
the hydraulic pump orifices clean.
The hydraulic pump load sense filters are located
inside the end of each hydraulic hose connected
to the load sense port on the top of each hydraulic
pump.
Check the filters for debris after every 800 hours
of operation. Hold each filter up to a light to see
how much of the filter may be blocked with debris.
Replace the filters when over half of the filter
appears to be blocked.
CHECKING THE LOAD SENSE FILTERS
1. Locate the two piston pumps underneath the
hopper. Locate the load sense port on each
pump. The load sense port is the 3/8” size
port coming out of the top of the pump.
2. Remove the hose from the fitting on the load
sense port on the pump.
3. Remove the filter screen from the hose end.
Hold the filter screen up to a light, and
inspect it for debris.
Replace the filters when over half of the filter
appears to be blocked.
4. Slide the new filter screen into the hose end
and reattach the hose to the fitting.
