Traction Circuit Component Failure
The traction circuit on Groundsmaster 5900 and 5910
machines is a closed loop system that includes the pis-
ton (traction) pump and four (4) wheel motors. If a com-
ponent in the traction circuit should fail, debris and
contamination from the failed component will circulate
throughout the traction circuit. This contamination can
damage other components inthe circuit so itmust be re-
moved to prevent additional component failure.
Oncethefilterhasbeenplacedinthecircuit,operatethe
traction circuit toallowoilflowthrough thecircuit. Thefil-
ter will remove contamination from the traction circuit
during circuit operation. The filter can be removed from
the machine after contamination has been removed
from the traction circuit.
IMPORTANT: When operating the traction system with
the high pressure filter installed, make sure that flow is
always directed through the filter before entering a re-
placed component (e.g. do not press the traction pedal
in the reverse direction if the filter is placed for forward
direction flow). If flow is reversed, debris from the filter
will re--enter the traction circuit.
If a component failure occurs in the traction circuit, it is
recommended that the entire traction circuit be disas-
sembled,drainedandthoroughly cleanedtoensurethat
all contamination is removed from the circuit. If any de-
brisremains inthetraction circuitand themachine isop-
erated, the debris can cause additional component
failure.
An alternative method of removing traction circuit con-
tamination would be to temporarily install a high pres-
surehydraulicoilfilter(seeSpecialTools)intothecircuit.
Thefiltershouldbeusedwhenconnectinghydraulictest
gauges in order to test traction circuit components or af-
ter replacing a failed traction circuit component (e.g.
traction (piston) pump or wheel motor). The filter will en-
sure that contaminates are removed from the closed
loop and thus, do not cause additional component dam-
age.
