point which can cause the solenoid to quit working. Or it can
even cause the connection point to weld together causing the
motor to run all of the time. In either of these failure modes the
solenoid needs to be replaced.You can jump the solenoid briefly
if needed to get a dump bed to the down position so you can
take it to be repaired.
-2) Oil leaking from power unit
Possible Reason…
When the battery is fully charged (with a power up/power down
pump) the unit is pumping an average of 2 gallons per minute
out. So the reservoir is seeing approximately 2 gallons out
and receiving approximately 2 gallons back from the hydraulic
cylinder, “at the same time”. But when the battery is low the
pump is pumping out less than 2 gallons but 2 gallons is still
coming into the reservoir. When this happens the reservoir can
overfill and the filler/breather cap (which has a filter/felt) can get
saturated (filled with hydraulic oil). Then the reservoir can no
longer breathe and becomes a pressure vessel. Then problems
can occur like the reservoir o-ring pushing out the side causing
a leak point or the reservoir will crack, also causing a leak point.
If you have a reservoir overfill once you can temporally remove
the filler/breather cap felt so the reservoir can continue to
breath. This may help prevent the reservoir from becoming a
pressure vessel. But once the battery is fully charged or replaced
the felt or filler breather cap needs to be replaced. This helps
keep airborne contamination from getting into the reservoir and
into the hydraulic fluid.
