Can you guys help out an old fossil like me? I have an older Huskee (speedco) 34 Ton with lack of power problem. After searching and reading up on it on this forum I decided to take a part the proportional valve to see if any was wrong with it. Well I took it apart and can't figure out how in the heck the one end goes back together (the end opposite the handle). Four small ball bearings (<1/8"), a spring and a one larger ball bearing (1/4") fell out of the cup/dust cover when I dissassembled it. I've tried several different configurations but none seem to work like the it did, slow return and/or return detent doesn't work. Any body know how this thing goes back together? It's a energy C1271 valve, tried looking on line for a schematic with no luck. BTW, still has low power, everything in the valve looked ok.
Thanks,
Thunder
==============================================
The detent for the valve spool which is designed to hold the valve
spool to divert oil flow uses the 4 steel balls and spring pressure
for a limited distance of travel to hold the spool in one postion
being the work position being forward or return position to the
fully retracted position.
Not knowing who built their valve prohibits me from detailing to you
the complete repair solution- if you are having thse many problems
as you stated you may need a new valve to replace that one.
the removal of the old valve and installing the new one will be easy to do.
==========================================================
If you have the paperwork that came with the splitter the valve should be
fully illustrated.
What has happened is the detent balls-which are the four small ball bearings
you mentioned have fallen out which they will do if the end cap and springs are
allowed to become separated-which is probably what occured due to excessive
wear or poor materials in the valve.
The detent balls hold the spool valve in place in either the forward and reverse
directions in which the cylinder travels.
As the valve is fully automatic the oil flow upon the cylinder stopping pushed the
valve spool back to the neutral open center position.
I would suggest obtaining a new valve simply based on your comments as the
valve spool surfaces will wear sooner than the cylinder packing as a rule and
oil will bypass quickly through a worn spool valve.
