Hydraulic/Mechanical Components Filters and Strainers
Service Tips
Only hand-tighten the filter. Do not use a filter wrench to tighten.
A light coating of oil on the gasket helps the seal to
seat properly and allows for easier
release at the time of removal.
Use of a filter and strainer is required to ensure warranty
. Units that do not use filters will
commonly experience reduced life of hydraulic components. Use of only strainers for very
cold weather and diesel fuels is acceptable. However, filters must be used when warm
weather returns. The use of only a strainer will not ensure long life of hydraulic
components.
About Strainers
Strainers are installed between the manifold and filter to trap larger particles leaving the fine
filtering to be done by the filter element. The strainer helps to prolong filter life by preventing
premature filter clogging. Strainers can also help reduce the frequency of filter change,
resulting from fungus and slime conditions. Always reinstall or replace the strainer.
DEF Strainer
Filtration is required to protect the nozzles and valves. The earlier versions of the dispenser
relied completely on a filter tank system. The later versions of the dispenser have a strainer.
The 100-micron strainer and assembly is compatible with DEF. The strainer must be cleaned
after the first air purging and calibration to ensure good flow rates. Refer to “Purging Air from
System” on page 6-9.
