Bobcat backhoe valve question

[RyanL]

Hi, Well i have a Melroe/Bobcat model 911 backhoe attachment, it has sit for a few yrs. The problem i am having is the dipper stick will not extend out unless you do some other function at the same time, it crowds itself back to you and and has power crowding but nothing extending, and the left stabilizer does the same thing by not having any power down unless you do another function at the same time and then it will lift the machine up and works fine. I have removed the valve assembly and cleaned a coulple spools but have not seen anything obvious. What should i look for? Or what is the problem?


Thanks in advance for any help.

I had trouble with the main boom down preesure on my 909 and it turned out to be the relief valves. There are ones for each section on the valve if I remember. Anyway it just eed a few orings changed in the relief and then it worked perfect again
