Here are some pics that seller sent me. At this point i dont have the
crane at my yard yet, transport company will deliver it some day soon (i hope
).
I've got couple pics about the valves. I asked seller to see if there is any print / text on the model label. In pic we can see he has scracthed scrab out of it to see if there is text, but
as he didnt notice anything and didnt clean it more I assume there werent text left anymore.
On Ebay, these new 4-
spool hydraulic valves doesnt cost much, like 150€ (around 1500Kr) including delivery.
These new valves also has this "Open center system", so all the time hydraulic fluid flows from pump to tank and it only uses small
control pressure.
Only when needed, it takes more
pressure from main line. Not sure does this old, original
valve has the same system.
My Ford 5610 has around 70l/min hydraulic
flow, so i assume it will need this open pump-to-tank line that
oil wont warm too much.
Gladly I have this Deluxe valves on Ford, so i can change flow rate from
switch, but not sure is this slower flowrate enough.
