5.10 Hydraulic System Cleanliness

Keeping the hydraulic oil clean is a vital factor affecting the service life
of hydraulic components. Oil in hydraulic systems is used not only to
transfer power, but also to lubricate the hydraulic components used in
the system. Keeping the hydraulic system clean will help avoid costly
downtime and repairs.
Major sources of hydraulic system contamination include:
•

Particles of dirt introduced when the hydraulic system is opened 
for maintenance or repair

•

Contaminants generated by the mechanical components of the 
system during operation

•

Improper storage and handling of hydraulic oil

•

Use of the wrong type of hydraulic oil

•

Leakage in lines and fittings

To minimize hydraulic oil contamination:
CLEAN hydraulic connections before opening the lines. When adding
oil, clean the hydraulic tank filler cap and surrounding area before
removing it.
AVOID opening the pumps, motors, or hose connections unless
absolutely necessary.
PLUG or cap all open hydraulic connections while servicing the
system.
CLEAN and cover the containers, funnels, and spouts used to store
and transfer the hydraulic oil.
CHANGE the hydraulic filters and oils at the recommended service
intervals.
