Is your pump remotely mounted or is the pump mounted on the piston? You say it needs
a hose, so I say pump is remotely mounted with a tank cause there are no hoses on the
cylinder mounted pump. Does it go up any amount? probably very low on oil which is
from the bad hose, run of the mill Napa hydraulic fluid is just fine. And yes you may
lose some fluid replacing and hose on hydraulic so catch it in a pan. As said Chelsea is
a major player with PTO's. My bet is it needs more hydraulic oil. Common weepy leak is
the cylinder rod which about all have a gland nut or collar needs tightening. Note If the
pump is on the cylinder and is out of oil you will have to raise the body with jacks or
lift it with a backhoe or something because the oil filler is on the piston = no way to fill
with the body down. We work on a lot of this stuff and most problem are so simple, keep
in mind the dump trucks duty cycle is on the low side, I mean in the trucking world in
general if you made 10 loads a day your doing good even local delivery's. I mean by
'duty cycles being low compared to loader backhoe is working 100% all day with high
hydraulic temps, but a dump truck body cylinder will never get warm. I can tell you in a heartbeat what you have but we need pictures of body, pump not interested in the truck
we have 5 from F6's to F8's. 1949 & 1950's 4 yd to 10yd bodys. just tryin ta help. Oh just remembered our 54 F800 has a frame mounted pump and a big hose to the piston with NO
tank so the oil fill is ON the piston. maybe thats what you have. sam
