HYDROSTATIC POWER TRAIN

Portable In-Line Filter

See Figure 5-1.

Figure 5-1

When hydraulic components fail internally, debris from 
the failed component can spread throughout the 
hydraulic system, causing additional damage.

This situation can be magnified when dealing with a 
closed loop traction system where oil is not filtered. In the 
event of a traction system component failure, It is 
recommended that all traction system components be 
disassembled and cleaned, or filtered using a portable 
in-line filter available through your Jacobsen Dealer. The 
portable in-line filter should also be used when testing 
hydraulic systems or after replacing a failed component.

IMPORTANT

Always install the in-line filter so oil flows through 
the filter before entering a component. Once filtering 
has begun, never reverse the flow of oil, or debris will 
re-enter the system.
