PROBLEM
CAUSE
SOLUTION
Hydraulic Toe Boards
"Creep" UP without the
valve control handles being
operated.
Can be a result of shock load
caused by improperly using
the toe boards to "cushion"
or break the fall of a cant
onto the bed):
· damaged hoses
· damaged cylinder seals or
cylinder
· damaged valve
INITIAL CHECK
To check, disconnect the toe board
hydraulic hose from its current valve
section and temporarily connect it to
another valve section. Check to see if
the hydraulics operate properly.
If hydraulics operate properly,
hoses
and cylinder seals are good. Perform
further valve inspection, found below.
If up creep still occurs,
check all
hoses for possible pinholes causing
leakage. Replace if applicable. Retest.
If up creep still occurs,
replace cylin-
der seals or cylinder and retest.
Be sure to reconnect the hose to the
proper valve section when done.
FURTHER VALVE INSPECTION
If further inspection of the valve is
required after initial check, remove the
check valve shown below. Flush the
check valve with an air hose or solvent
to remove any dirt from the valve's
seat. Reinstall and test again. Check to
see if the hydraulics operate properly.
If up creep still occurs,
replace the
check valve with a new one. Retest.
If
up creep still occurs,
replace the
hydraulic valve.
